Descrizione dell’ invenzione industriale dal titolo : “Nuovo sistema industriale per la realizzazione di celle in matrice polimerica termoplastica ad alta porosità per batterie/pile per produzione di energia elettrica attivate con addizione di acqua a ph neutro ” a nome di : Description of the industrial invention entitled: "New industrial system for the production of cells in high porosity thermoplastic polymer matrix for batteries / cells for the production of electricity activated with the addition of water at neutral pH" in the name of:
Descrizione Description
I sistemi tradizionali di produzione di celle per batterie/pile per immaganizamento/produzione di energia elettrica si basano su reazione elettrochimica o su reazioni con “sostanze di alimentazione” (es. fuel celi a idrogeno ), i costi di realizzazione delle stesse sono mediamente elevati e nei processi allo stato dell'arte non vengono utilizzati materiali di riciclo, tantomeno esistono celle di batterie totalmente riciclabili. Traditional systems for the production of cells for batteries / cells for storage / production of electricity are based on electrochemical reactions or reactions with "feed substances" (eg. Hydrogen fuel cells), the costs of making them are on average high and in state-of-the-art processes no recycled materials are used, nor are there fully recyclable battery cells.
Il sistema oggetto della presente invenzione si basa sulla realizzazione di celle in matrice polimerica termoplastica ad alta porosità, realizzate sia con materiali “vergini” che da riciclo caratterizzate da moltepilici cicli di carica eseguiti solo attraverso apporto per assorbimento della cella di acqua a ph neutro. Lo spessore delle celle è compreso tra 0.6 mm e 1.2 mm divisi in tre strati su medesima matrice : The system object of the present invention is based on the realization of cells in high porosity thermoplastic polymeric matrix, made both with "virgin" and recycled materials characterized by multiple charging cycles performed only through the absorption of water at neutral pH by the cell. The thickness of the cells is between 0.6 mm and 1.2 mm divided into three layers on the same matrix:
1 uno strato inferione di spessore compreso tra 0.1 - 0.2 mm di polvere di grafite 1 a lower layer with a thickness of between 0.1 - 0.2 mm of graphite powder
2 uno strato intermedio di polvere fibra di carbonio da riciclo o altro materiale ad altissimo contenuto di carbonio di varia natura e di granulometria compresa tra 10 e 70 micron, di spessore compreso tra 0.4 e 0.8 mm. 2 an intermediate layer of recycled carbon fiber powder or other material with a very high carbon content of various nature and with a particle size between 10 and 70 microns, with a thickness between 0.4 and 0.8 mm.
3 uno strato superiore di polvere di ossidi puri o in miscela e silice micronizzata e/o metalli semi-conduttori e/o ceneri leggere da inceneritori contenenti percentuali di metalli pesanti, ossidi, fosfati, sali, di spessore compreso tra 0.1 e 0.2 mm. 3 an upper layer of powder of pure or mixed oxides and micronized silica and / or semi-conductive metals and / or light ash from incinerators containing percentages of heavy metals, oxides, phosphates, salts, with a thickness between 0.1 and 0.2 mm.
4 Lamine di spessore 2/100 di mm a chiusura inferiore e superiore della cella in alluminio e/o rame e/o argento. con funzione di elettrodi. 4 Laminates 2/100 mm thick with lower and upper closure of the cell in aluminum and / or copper and / or silver. with function of electrodes.
(disegno 1) (drawing 1)
La quantità della matrice legante polimerica termoplastica varia tra il 5% e l'8% dell'intera massa/cella, il/i polimero/i sono di tipologia PS - ABS - SAN - PVDF - PC - PVC e/o lutti i polimeri solubili in chetoni. La percentuale di polveri componenti le cariche sui tre strati variano tra il 95% e il 98%. The quantity of the thermoplastic polymer binder matrix varies between 5% and 8% of the entire mass / cell, the polymer (s) are of type PS - ABS - SAN - PVDF - PC - PVC and / or all polymers soluble in ketones. The percentage of powders composing the fillers on the three layers varies between 95% and 98%.
Il processo di produzione si basa sulla miscelazione delle polveri componenti ogni strato con il polimero o i blends di polimeri della tipologia sopradescritta, con apposito macchinario/impianto che poi attraverso un processo di laminazione e successivo accoppiamento attraverso un sistema di pressione a rulli o pressa realizza una lastra sottile in medesima matrice, a carica differenziata ed altissima porosità, che realizza dei contatti non di superficc, tra i vari elementi, ma tridimensionali tra gli elementi componenti la cella.che vengono imbevuti con acqua a ph neutro. The production process is based on the mixing of the powders that make up each layer with the polymer or polymer blends of the type described above, with a special machinery / plant which then through a lamination process and subsequent coupling through a roller or press pressure system creates a thin plate in the same matrix, with differentiated charge and very high porosity, which creates three-dimensional contacts between the elements that make up the cell, which are soaked with water with a neutral pH.
Le celle così realizzate possono essere utilizzate per realizzare pile/batterie a molteplici cicli di ricarica, ricarica che avviene immediatamente per assorbimento di acqua. The cells thus made can be used to make cells / batteries with multiple recharging cycles, recharging that occurs immediately by absorption of water.
VANTAGGI DELLA PRESENTE INVENZIONE ADVANTAGES OF THIS INVENTION
La presente invenzione e la tecnologia correlata permettono di ottenere i seguenti vantaggi rispetto ai sistemi convenzionali finora utilizzati: The present invention and the related technology allow to obtain the following advantages with respect to the conventional systems used up to now:
• Celle completamente riciclabili a fine vita essendo in matrice termoplastica. • Completely recyclable cells at the end of their life being in thermoplastic matrix.
• Semplificazione dell’ impianto ed abbattimento significativo della gestione dei costi se paragonati a sistemi tradizionali per la produzione di celle per pile/batterie. • Simplification of the system and significant reduction in cost management when compared to traditional systems for the production of cells for cells / batteries.
• Possibilità di riutilizzare materiali ad altissimo costo di smaltimento (ceneri leggere da termovalorizzatori o altro tipo di inceneritori), inertizzandoli nella matrice polimerica termoplastica e realizzando recupero/produzione di energia, e quindi ammortizzando i costi di smaltimento/inertizzazione. • Possibility of reusing materials with a very high disposal cost (fly ash from waste-to-energy plants or other type of incinerators), inerting them in the thermoplastic polymer matrix and realizing energy recovery / production, and therefore amortising disposal / inertization costs.
• Ottenimento di balterie/pile con ciclo vita molto lungo e tempi di ricarica pressoché immediati. • Obtaining of balterias / batteries with a very long life cycle and almost immediate recharging times.
• Possibilità di utilizzare materiali termoplastici da riciclo anche molto poveri e difficili da riciclare (EPS polistirolo espanso da imballaggi) come matrice polimerica della cella. • Possibility of using recycled thermoplastic materials, even very poor and difficult to recycle (EPS expanded polystyrene from packaging) as the polymeric matrix of the cell.
ESEMPI EXAMPLES
Esempio 1 - Preparazione di una cella composta da ceneri leggere da elettrofiltro di termovalorizzalore alimentato a CDR - polvere di fibra di carbonio da riciclo - polvere di grafite in matrice EPS (polistirolo espanso) da riciclo. Example 1 - Preparation of a cell composed of light ash from a waste-to-energy electrofilter fed with RDF - recycled carbon fiber powder - recycled graphite powder in EPS matrix (expanded polystyrene).
Secondo il presente esempio, vengono realizzate delle miscele separate di EPS polisterolo espanso (da riciclo) con ceneri leggere da elettrofiltro di termovalorizzatore alimentato a CDR, di EPS polisterolo espanso (da riciclo) con polvere di fibra di carbonio da riciclo e di EPS polisterolo espanso (da riciclo) con polvere polvere di grafite in percentuali variabli dei rispettivi componenti in intervalli da 0 a 100%. Tale miscela , su base 100, c costituita da 5 parti di EPS (da riciclo), 10 parli di acetone e 85 parti come valore complessivo delle varie polveri. Dette polveri subiscono una prima miscelazione con macchinario adeguato. Nella prima fase il EPS viene disciolto nel chetone (acetone) nel rapporto 1 :2 parti, successivamente la resina così ottenuta viene miscelata, con l'ausilio di macchinario adeguato con sistema a sigma o a coclea miscelante, singolarmente con le varie polveri ottenendo in pochi minuti tre bulk (masse) che poi con ausilio di cilindri contrapposti (calandre/laminatoio) o pressa a compressione vengono prima ridotti in lamine e poi accoppiati ottenendo una lastra di dimensione 40 mm x 40 mm c spessore di 1 mm a cariche differenziate, dove sui lati inferiore e superiore vengono apposte delle lamine di rame con funzione di elettrodi di dimensioni 40 mm x 40 mm e spessore 0.02 mm. Il peso della cella è pari a 3 gr. E viene fatta assorbire acqua a PI I neutro per 1.5 gr. According to the present example, separate mixtures of EPS polystyrol foam (from recycle) with fly ash from an electro-filter of waste-to-energy plant powered by RDF, EPS polystyrol foam (from recycle) with carbon fiber powder from recycle and EPS polystyrol foam are made (from recycle) with graphite powder in varying percentages of the respective components in ranges from 0 to 100%. This mixture, based on 100, is made up of 5 parts of EPS (from recycle), 10 parts of acetone and 85 parts as a total value of the various powders. Said powders undergo a first mixing with suitable machinery. In the first phase, the EPS is dissolved in the ketone (acetone) in the ratio of 1: 2 parts, then the resin thus obtained is mixed, with the aid of suitable machinery with a sigma system or a mixing screw, individually with the various powders, obtaining in a few minutes three bulk (masses) which then with the aid of opposing cylinders (calenders / rolling mill) or compression press are first reduced into sheets and then coupled to obtain a sheet of size 40 mm x 40 mm with a thickness of 1 mm with different loads, where on the lower and upper sides are affixed copper sheets with the function of electrodes of dimensions 40 mm x 40 mm and thickness 0.02 mm. The weight of the cell is equal to 3 gr. And it is made to absorb water at neutral PI I for 1.5 gr.
Procedendo poi alla misurazione dei valori in volts e mA otteniamo rispettivamente 1.2 volts e 5 mA per cm2 come valori assoluti. Proceeding then to the measurement of the values in volts and mA we obtain respectively 1.2 volts and 5 mA per cm2 as absolute values.
La cella viene poi messa sotto carico con resistenza a 12 Ohm 1 watt ottenendo fesaurimento della stessa in cerca 10 ore e riattivandola in pochi secondi per apporto di acqua riportandola ai valori iniziali. 11 processo di scarica con stessa durata e riattivazione viene ripetuto per 20 cicli ottenedo sempre la riattivazione della cella pressoché ai valori iniziali. The cell is then put under load with a resistance of 12 Ohm 1 watt, obtaining its breakdown in search of 10 hours and reactivating it in a few seconds by adding water, bringing it back to the initial values. The discharge process with the same duration and reactivation is repeated for 20 cycles, always obtaining the reactivation of the cell almost to the initial values.
Esempio 2 - Preparazione di una cella composta da miscela di biossido di titanio, silice micronizzata, ossido di zinco - polvere di fibra di carbonio da riciclo - polvere di grafite in matrice SMMA Example 2 - Preparation of a cell composed of a mixture of titanium dioxide, micronized silica, zinc oxide - recycled carbon fiber powder - SMMA matrix graphite powder
Secondo il presente esempio, vengono realizzate delle miscele separate di SMMA (Stirolo metilmetacrilato). con miscela di biossido di titanio - silice micronizzata - ossido di zinco, di SMMA (Stirolo metilmetacrilato)con polvere di fibra di carbonio da riciclo, di SMMA (Stirolo metilmetacrilato) con polvere polvere di grafite in percentuali variabli dei rispettivi componenti in intervalli da 0 a 100%. Tale miscela , su base 100, è costituita da 5 parti di SMMA, 10 parti di acetone e 85 parti come valore complessivo delle varie polveri. Dette polveri subiscono una prima miscelazione con macchinario adeguato. Nella prima fase lo SMMA viene disciolto nel chetone (acetone) nel rapporto 1 :2 parti, successivamente la resina così ottenuta viene miscelata, con l'ausilio di macchinario adeguato con sistema a sigma o a coclea miscelante, singolarmente con le varie polveri ottenendo in pochi minuti tre bulk (masse) che poi con ausilio di cilindri contrapposti (calandre/laminatoio) o pressa a compressione vengono prima ridotti in lamine e poi accoppiati ottenendo una lastra di dimensione 40 mm x 40 mm e spessore di 1 mm a cariche differenziate, dove sui lati inferiore c superiore vengono apposte delle lamine di rame con funzione di elettrodi di dimensioni 40 mm x 40 mm e spessore 0.02 mm. Il peso della cella è pari a 3.4 gr. E viene fatta assorbire acqua a PH neutro per 1.1 gr. According to the present example, separate mixtures of SMMA (Styrene methylmethacrylate) are made. with a mixture of titanium dioxide - micronized silica - zinc oxide, of SMMA (Styrene methyl methacrylate) with recycled carbon fiber powder, of SMMA (Styrene methyl methacrylate) with powder of graphite powder in varying percentages of the respective components in intervals of 0 at 100%. This mixture, based on 100, is made up of 5 parts of SMMA, 10 parts of acetone and 85 parts as a total value of the various powders. Said powders undergo a first mixing with suitable machinery. In the first phase, the SMMA is dissolved in the ketone (acetone) in the ratio of 1: 2 parts, then the resin thus obtained is mixed, with the aid of suitable machinery with a sigma system or a mixing screw, individually with the various powders, obtaining in a few minutes three bulk (masses) which then with the aid of opposing cylinders (calenders / rolling mill) or compression press are first reduced into sheets and then coupled to obtain a sheet with a size of 40 mm x 40 mm and a thickness of 1 mm with different loads, where on the lower and upper sides are affixed copper sheets with the function of electrodes of dimensions 40 mm x 40 mm and thickness 0.02 mm. The weight of the cell is equal to 3.4 gr. And it is made to absorb water at neutral PH for 1.1 gr.
Procedendo poi alla misurazione dei valori in volts e mA otteniamo rispettivamente 1.5 volts e 7 mA per cm2 come valori assoluti. Proceeding then to the measurement of the values in volts and mA we obtain respectively 1.5 volts and 7 mA per cm2 as absolute values.
La cella viene poi messa sotto carico con resistenza a 12 Ohm 1 watt ottenendo l'esaurimento della stessa in cerca 11 ore e riattivandola in pochi secondi per apporto di acqua riportandola ai valori iniziali. Il processo di scarica con stessa durata e riattivazione viene ripetuto per 20 cicli ottenedo sempre la riattivazione della cella pressoché ai valori iniziali. The cell is then put under load with a resistance of 12 Ohm 1 watt obtaining the exhaustion of the same in search of 11 hours and reactivating it in a few seconds by adding water, bringing it back to the initial values. The discharge process with the same duration and reactivation is repeated for 20 cycles, always obtaining the reactivation of the cell almost to the initial values.
Esempio 3 - Preparazione di una cella composta da miscela di biossido di titanio, nanopolveri di silice , polvere di zinco da riciclo - polvere di fibra di carbonio da riciclo -polvere di grafite - in matrice SMMA Example 3 - Preparation of a cell composed of a mixture of titanium dioxide, silica nanopowders, recycled zinc powder - recycled carbon fiber powder - graphite powder - in SMMA matrix
Secondo il presente esempio, vengono realizzate delle miscele separale di SMMA (Stirolo metilmetacrilato). con miscela di biossido di titanio - nanopolveri di silice - polvere di zinco da riciclo, di SMMA (Stirolo melilmetacrilato)con polvere di fibra di carbonio da riciclo, di SMMA (Stirolo metilmetacrilato) con polvere polvere di grafite in percentuali variabli dei rispettivi componenti in intervalli da 0 a 100%. Tale miscela , su base 100, è costituita da 5 parti di SMMA , 10 parti di acetone e 85 parli come valore complessivo delle varie polveri. Dette polveri subiscono una prima miscelazione con macchinario adeguato. Nella prima fase lo SMMA viene disciolto nel chetone (acetone) nel rapporto 1 :2 parti, successivamente la resina così ottenuta viene miscelata, con l'ausilio di macchinario adeguato con sistema a sigma o a coclea miscelante, singolarmente con le varie polveri ottenendo in pochi minuti tre bulk (masse) che poi con ausilio di cilindri contrapposti (calandre/laminatoio) o pressa a compressione vengono prima ridotti in lamine e poi accoppiati ottenendo una lastra di dimensione 40 mm x 40 mm e spessore di 1 mm a cariche differenziate, dove sui lati inferiore e superiore vengono apposte delle lamine di rame con funzione di elettrodi di dimensioni 40 mm x 40 mm e spessore 0.02 mm. Il peso della cella è pari a 4.2 gr. E viene fatta assorbire acqua a PH neutro per 1.3 gr. According to the present example, separal mixtures of SMMA (Styrene methylmethacrylate) are made. with a mixture of titanium dioxide - silica nanopowders - recycled zinc powder, of SMMA (Styrol melylmethacrylate) with recycled carbon fiber powder, of SMMA (Styrene methylmethacrylate) with powder of graphite powder in varying percentages of the respective components in ranges from 0 to 100%. This mixture, on a 100 basis, is made up of 5 parts of SMMA, 10 parts of acetone and 85 parts as a total value of the various powders. Said powders undergo a first mixing with suitable machinery. In the first phase, the SMMA is dissolved in the ketone (acetone) in the ratio of 1: 2 parts, then the resin thus obtained is mixed, with the aid of suitable machinery with a sigma system or a mixing screw, individually with the various powders, obtaining in a few minutes three bulk (masses) which then with the aid of opposing cylinders (calenders / rolling mill) or compression press are first reduced into sheets and then coupled to obtain a sheet with a size of 40 mm x 40 mm and a thickness of 1 mm with different loads, where on the lower and upper sides are affixed copper sheets with the function of electrodes of dimensions 40 mm x 40 mm and thickness 0.02 mm. The weight of the cell is equal to 4.2 gr. And it is made to absorb water at neutral PH for 1.3 gr.
Procedendo poi alla misurazione dei valori in volts e mA otteniamo rispettivamente 1.5 volts e 10 mA per cm2 come valori assoluti. Proceeding then to the measurement of the values in volts and mA we obtain respectively 1.5 volts and 10 mA per cm2 as absolute values.
La cella viene poi messa sotto carico con resistenza a 12 Ohm 1 watt ottenendo l'esaurimento della stessa in cerca 13 ore e riattivandola in pochi secondi per apporto di acqua riportandola ai valori iniziali. Il processo di scarica con stessa durata e riattivazione viene ripetuto per 20 cicli ottenedo sempre la riattivazione della cella pressoché ai valori iniziali. The cell is then put under load with a resistance of 12 Ohm 1 watt obtaining the exhaustion of the same in search of 13 hours and reactivating it in a few seconds by adding water, bringing it back to the initial values. The discharge process with the same duration and reactivation is repeated for 20 cycles, always obtaining the reactivation of the cell almost to the initial values.
