Description
2 * t * « t * der består af to stive, mikroporøse, elektrisk isolerende plader, der er modstandsdygtige over for elektrolytten og er udformet med indvendige og udvendige noter til fri cirkulation af elektrolytten. Kanterne af de stive plader rager uden for akkumulatorpladernes kanter og presses mod hinanden, hvorpå de fastklemmes og sammensvejses. Ulempen ved denne udformning er, at lommen over hele omkredsen får en tyk og pladskrævende kantvulst.2 * t * «t * consisting of two rigid, microporous, electrically insulating plates resistant to the electrolyte and formed with inner and outer grooves for free circulation of the electrolyte. The edges of the rigid plates extend beyond the edges of the accumulator plates and are pressed against each other, whereupon they are clamped and welded together. The disadvantage of this design is that the pocket over the entire perimeter gets a thick and space-intensive edge bump.
Opfindelsen tager sigte på at afhjælpe disse ulemper, og med henblik herpå er fremgangsmåden ifølge opfindelsen ejendommelig ved, at der anvendes separator-plader af polyesterindeholdende fenolharpiks eller af polyvinylklorid, og at der langs pladernes kanter påføres i pastaagtig tilstand et hurtigt hærdende bånd af polyethylenkopolymer tilsat syntetisk akrylgummi.SUMMARY OF THE INVENTION The present invention aims to alleviate these disadvantages, and for this purpose the method according to the invention is characterized by the use of polyester-containing phenol resin or polyvinyl chloride separator plates and a fast-curing band of polyethylene copolymer is applied along the edges of the plates. synthetic acrylic rubber.
Ved at fremstille separatoren som ovenfor angivet undgår man støbeoperationer og de dermed forbundne vanskeligheder. Det hurtigt hærdende bånd giver en fast og stiv forbindelse, og fremstillingen er væsentligt enklere.By manufacturing the separator as stated above, it avoids molding operations and the associated difficulties. The fast curing band provides a firm and rigid connection, and manufacturing is significantly simpler.
Opfindelsen forklares nærmere i det følgende under henvisning til den skematiske tegning, hvor fig. 1 viser et perspektivisk, delvis skåret billede af en separator ifølge opfindelsen med indsat akkumulatorplade, og fig, 2 et snit langs linien A-A i fig. 1.The invention is explained in more detail below with reference to the schematic drawing, in which fig. 1 shows a perspective, partially cut view of a separator according to the invention with inserted accumulator plate, and fig. 2 is a section along the line A-A in fig. First
Tegningen viser en akkumulatorplade 1 med tilhørende pladefane 7.The drawing shows an accumulator plate 1 with associated plate tab 7.
Akkumnlatorpladen er indsat i en lomme, der danner separatoren ifølge opfindelsen, og som består af to stive, elektrisk isolerende plader 2 og 3, der er modstandsdygtige overfor elektrolyten 4, De mod akkumulatorpladen 1 vendende sider af disse to plader er udformet med ribber 10 og noter til bedre fjernelse af de gasser, der opstår som følge af den elektrokemiske reaktion. På ydersiden har pladerne 2 og 3 noter 11, som fremmer cirkulationen af elektrolyten mellem to ved siden af hinanden beliggende plader.The accumulator plate is inserted into a pocket forming the separator according to the invention, which consists of two rigid, electrically insulating plates 2 and 3 which are resistant to the electrolyte 4, the sides of the two plates facing the accumulator plate are formed with ribs 10 and notes for better removal of the gases generated by the electrochemical reaction. On the outside, plates 2 and 3 have grooves 11 which promote the circulation of the electrolyte between two adjacent plates.
Langs siderne og forneden er pladerne 2 og 3 forbundet med hinanden ved hjælp af et bånd 5 af plastmateriale. Foroven er pladernes kanter forbundet med hinanden ved hjælp af et bånd 6 af sanmte art som båndet 5, efter at akkumulatorpladen 1 er blevet anbragt inden i lommen.Along the sides and bottom, the plates 2 and 3 are connected to each other by means of a band 5 of plastic material. Above, the edges of the plates are connected to each other by means of a band 6 of the same kind as the band 5, after the accumulator plate 1 has been placed inside the pocket.
I en anden udførelsesform for opfindelsen behøver separatorlommen ikke at være lukket over hele sin omkreds.In another embodiment of the invention, the separator pocket need not be closed over its entire circumference.
Pladerne 2 og 3 kan bestå af en polyesterindeholdende phenolharpiks eller af mikroporøst PVC-skum med åbne porer med en radius mellem ca. 1 og ca. 7 μ, således at den samlede porøsitet for separatoren ifølge opfindelsen ligger mellem 75 og 80 %.Plates 2 and 3 may consist of a polyester-containing phenolic resin or of open-pore microporous PVC foam having a radius of between approx. 1 and approx. 7 µ so that the total porosity of the separator according to the invention is between 75 and 80%.
Til fremstilling af pladerne 2 og 3 kan man også anvende en blanding af PVC, pulverformet siliciumoxyd, vand og cyklohexanol til opnåelse af en porøsitetFor the preparation of plates 2 and 3, a mixture of PVC, powdered silica, water and cyclohexanol can also be used to obtain a porosity.
