Definitions
- Lithium metal with a phosphorus-containing passivating agent in an organic solvent Lithium metal with a phosphorus-containing passivating agent in an organic solvent.
- Lithium belongs to the alkali metals. Like the heavier element homologue, it is characterized by a strong reactivity to a variety of substances. So it reacts violently, often with inflammation with water,
- Alcohols and other substances containing protic hydrogen It is unstable in air and it reacts with oxygen, nitrogen and carbon dioxide. It is therefore normally handled under inert gas (noble gases such as argon) and stored under a protective layer of paraffin oil.
- Coating typically becomes liquid lithium in an inert
- Another method of stabilizing lithium metal is to heat it above its melting point, stir the molten lithium, and contact it with a fluorinating agent, such as perfluoropentylamine (WO 2007/005983 A2).
- a fluorinating agent such as perfluoropentylamine
- Lithium metal powders relatively much coating agent is spent. In the examples of said patent application about 1%.
- US 2008 / 0283155A1 describes a process for stabilizing lithium metal characterized by the steps of: a) heating lithium metal powder above the melting point to produce molten lithium metal, b)
- Lithium powder must first be melted and the coating is carried out at temperatures above the lithium melting point. On the one hand, the relatively high temperatures require a corresponding expenditure of energy, on the other hand, molten lithium has an extremely corrosive effect on various materials such as glasses, sealants and many metallic materials such as
- the polymer may be selected from the group of polyurethanes, PTFE, PVC, polystyrene and the like.
- a disadvantage of this method is that the protected lithium metal gets an undefined surface coating of organic substances that can interfere with its use, for example, for the prelithiation of electrode materials.
- a process is proposed for coating lithium metal with a passivating topcoat
- Lithium surface causes.
- the surface-passivated lithium metal has a composite topcoat containing or consisting of at least two sparingly soluble lithium-containing components.
- the composite topcoat preferably contains or consists of the sparingly soluble components lithium carbonate, lithium fluoride and lithium metaphosphate.
- the composite top layer particularly preferably contains or consists of the sparingly soluble components lithium carbonate and lithium metaphosphate.
- the phosphorus content is 0.01 to 2 mass%, preferably 0.03 to 1 mass% of the surface-passivated lithium metal.
- the preparation of the surface-passivated lithium metal is carried out in such a way that lithium chloride is below 180 ° C., ie in the solid state with a passivating agent of the general formula
- the passivating agent used is preferably lithium fr / s (oxalato) phosphate. That lithium metal is treated in the temperature range between 100 and 175 ° C with the passivating agent.
- aprotic solvents are hydrocarbons, ethers or
- the solvents used are preferably aromatic hydrocarbons, preferably toluene, xylenes, cumene or tetralin.
- the passivating agent is used in dissolved form.
- ethers are preferably THF, THP; Esters, preferably ethyl acetate, butyl butyrate; Lactones preferably ⁇ -butyrolactone (GBL) or carbonic acid ester, preferably ethylene carbonate, propylene carbonate, dimethyl carbonate or mixtures of the solvents mentioned used.
- the lithium metal is used as a powder with a particle size ⁇ 0.5 mm, granules with a particle size in the range of 0.5 mm to 10 mm or foil with a thickness of up to 1 mm.
- the powder has an average particle size (D50) of ⁇ 200 ⁇ , preferably ⁇ 100 ⁇ and particularly preferably ⁇ 50 ⁇ on.
- D50 average particle size
- the contact time between the passivating agent and the lithium metal is at least 5 minutes, preferably at least 10 minutes.
- the passivating agent is in a molar ratio of 0.2 to 20: 1000
- 1000 preferably 0.05 to 0.5: 1000 based on granules or film used.
- the passivating agent is a phosphorus-containing substance of the general formula
- Li [P (C 2 O 4 ) 3 - x / 2 FJ with x 0, 2 or 4 used.
- x 0, ie, the passivating agent is fluorine-free, with particular preference being given to lithium fr / s (oxalato) phosphate (“LiTOP”) as the passivating agent.
- LiTOP lithium fr / s (oxalato) phosphate
- LiTOP decomposes at temperatures above about 140 ° C according to the following reaction equation: n LiP (C 2 O 4 ) 3 - -> (LiPO 3 ) n + 3 n CO 2 + 3 n CO
- Passivating agent as a solution in a non-inert, polar aprotic
- the protective film may additionally contain degradation products of this solvent.
- the method according to the invention has the following advantages:
- Reaction can be prepared with phosphoric acid.
- the passivation active ingredients are formed by decomposition of the
- Phosphorus (P) -containing passivation agent in homogeneous phase, i. All lithium particles are uniformly contacted and coated with the passivating agent.
- the surface-passivated lithium metal according to the invention is suitable for the chemical lithiation of electrochemically active materials, preferably graphite,
- Fig. 1 Thermal behavior of the LiTOP-coated Li powder from Example 1 at 40 ° C storage
- Fig. 2a Thermal behavior of the uncoated Li powder
- Metal content 98.5% by mass (determined by gas volumetric method)
- Coated lithium metal powder, prepared as in Example 1 is subjected to the official UN test N.2, the test for pyrophoric properties of solids. In none of the individual experiments was an ignition of the powder observed. The product can therefore be classified as non-pyrophoric. Comparative Example 1
