Definitions
- LiPON polymeric lithium phosphorus oxynitride
- the present invention relates to wet-chemically produced polymeric lithium phosphorus oxynitride (LiPON), a method for its production, uses thereof and a battery which contains a solid-state electrolyte produced from the LiPON according to the invention.
- the present invention also relates to a method for producing a corresponding battery.
- lithium-ion batteries consist of a graphite anode, a transition metal cathode and a liquid electrolyte.
- the next generation of lithium-ion batteries should be able to store significantly more energy than before, which requires the use of new electrode materials.
- metallic lithium reacts with practically all known electrolytes, which is what the im Electrolytes used commercially at the moment lead to gas and heat release and thus to the destruction of the battery.
- these electrodes show strong changes in volume during the charge and discharge cycles, which among other things leads to the formation of dendrites.
- Solid-state electrolytes therefore have to have a high Li + conductivity in order to ensure the functionality of the battery, but at the same time also form an advantageous SEI.
- This must be chemically, electrochemically and mechanically stable in order to withstand both the reactivity of the lithium metal and the changes in volume of the anode. Otherwise you will encounter the problems described in the first chapter.
- LiPON vitreous lithium phosphorus oxynitride
- the LiPON known in the literature is a material from the class of glasses. Glasses are amorphous, non-metallic, inorganic materials in which the individual atoms are connected to one another by covalent and / or ionic bonds (according to literature, these include Li 2 0, P 2 0 5 and PON (Dudney, NJ (2000), Addition of a thin-film inorganic solid electrolyte (LiPON) as a protective film in lithium batteries with a liquid electrolyte, Journal of Power Sources, 89 (2), 176-179)). Glasses are traditionally manufactured using a melting process. The starting materials (z. B.
- Si0 2 and metal oxides (CaO, Na 2 O, MgO, etc.) as additives) are mixed, melted and shaped in the molten state.
- Thin layers with a vitreous structure can be produced using gas-phase deposition processes (e.g. sputtering).
- LiPON is typically deposited on surfaces by sputtering Li 3 P0 4 in a nitrogen atmosphere (Schwöbei, A., Hausbrand, R., & Jaggermann, W. Interface reactions between LiPON and lithium studied by in situ X-ray photoemission, Solid State lonics (2015) 273, 51-54).
- the starting material in this case is ceramic (crystalline) Li 3 P0 4 in monolithic form, which serves as a target. Bombardment with ions removes fragments from the target. These react with nitrogen and are deposited on a selected carrier medium (substrate).
- the stoichiometry is controlled via process parameters (such as sputter rate and nitrogen pressure). This manufacturing process requires a high vacuum, which is therefore very complex and limits the application scale.
- a LiPON layer cannot be created free-standing, but only deposited on a substrate.
- the task of the present invention is the production of a solid electrolyte which has a high Li + conductivity and good processability as well as a stable SEI in contact with lithium metal anodes.
- the solid electrolyte should be able to be produced in a way other than PVD or CVD processes, in particular sputtering, which in the case of conventional solid electrolytes requires a high level of equipment and is associated with significant cost disadvantages.
- LiPON polymeric lithium phosphorus oxynitride
- Claim 4 specifies a method for its production.
- Claim 12 describes uses of the LiPON according to the invention, while claim 13 describes a battery that contains a solid electrolyte formed from the LiPON according to the invention.
- claim 17 a method for producing the battery according to the invention is specified.
- the present invention thus relates to a wet-chemically produced polymer lithium phosphorus oxynitride (LiPON), containing a repeat unit according to the general formula I,
- LiPON is soluble in solvents selected from the group consisting of dimethyl sulfoxide (DMSO), tetrahydrofuran (THF), toluene and N-methylpyrrolidone (NMP).
- solvents selected from the group consisting of dimethyl sulfoxide (DMSO), tetrahydrofuran (THF), toluene and N-methylpyrrolidone (NMP).
- the LiPON according to the invention differs from the previously known sputtered or crystalline LiPON in that it is based on wet chemical white se, ie in a solvent, was prepared. The time-consuming process of sputtering is no longer necessary.
- the LiPON according to the invention is therefore not a ceramic, but an amorphous, polymeric material that - unlike the sputtered or high-temperature synthesis ceramic variants of LiPON - in polar solvents such as dimethyl sulfoxide, tetrahydrofuran, toluene or N-methylpyrrolidone - can be solved.
- the LiPON according to the invention thus opens up completely new possibilities for use and processing. For example, it is possible to isolate the LiPON and handle it as such. It is also possible to separate the LiPON from solutions, for example by film casting or knife coating, etc.
- the complex application processes known from the prior art such as PVD (sputtering) or CVD processes, which must be carried out in a vacuum or under a protective gas atmosphere with high energy expenditure, can be avoided.
- the electrolyte Since the reactivity of metallic lithium cannot be bypassed, the electrolyte must be such that it breaks down into precisely defined products and forms a specific, stable SEI.
- the SEI from LiPON mentioned at the beginning serves as a template.
- the formation of the lithium salts Li 3 N, Li 3 P and Li 2 O requires that the new solid electrolyte has a chemical molecular formula similar to that of the vitreous LiPON.
- a suitable class of material for this approach are polyphosphazenes, which have a phosphorus-nitrogen main chain. Through certain chemical modification, so-called polymeric LiPON with the empirical formula [Li 2 P0 2 N] n can be produced, which is almost identical to the empirical formula of vitreous LiPONs.
- polyphosphazenes are known solid electrolytes that can achieve Li + conductivities of up to 10 3 sem 1 , which is comparable to the liquid electrolytes currently in use.
- this solid-state electrolyte offers the previously unattained combination of stable SEI and high Li + conductivity.
- the polymer LiPON according to the invention is a thermoplastic and thus meltable, which makes it can also be processed on a large technical scale by means of known processes such as the roll-to-roll method.
- the LiPON according to the invention can in particular be converted into a poly (metaphosphinic acid) according to the general formula II

- the poly (metaphosphinic acid) is preferably prepared immediately before it is converted into the LiPON according to the invention. It is particularly preferred here if the two-stage reaction is carried out as a one-pot synthesis.
- the poly (dichlorophosphazene) is reacted with dimethyl sulfoxide to form poly (metaphosphinic acid), the resulting solution of poly (metaphosphinic acid) in DMSO is immediately further reacted with the organolithium compound to form the polymeric LiPON according to the invention.

- the conversion to LiPON can advantageously take place over a period of 10 minutes to 7 days, preferably from 12 hours to 5 days, at a temperature from -20.degree. C. to + 60.degree. C., preferably at 0.degree. C. to 40.degree preferably at 10 to 30 ° C, and / or a concentration of poly (metaphosphinic acid) according to Formula II from 1 to 200 g / l, preferably 10 to 100 g / l, can be carried out.
- the polymeric lithium phosphorus oxynitride is preferably solidified, in particular by precipitation, crystallization, extraction and / or removal of the solvent.
- LiPON according to the invention is precipitated, this is done in particular by adding a nitrile-containing solvent, in particular acetonitrile.
- the present invention relates to the use of the LiPON according to the invention as a solid electrolyte.

- the solid electrolyte is produced only from the LiPON according to the invention, for example by means of doctor blades, film casting and / or pressing.
- the solid electrolyte presented here is suitable for large-scale industrial production of high-energy lithium-ion bulk batteries with lithium metal anodes.
- the most important advantage of the LiPON according to the invention is that the reactivity of the metallic lithium is not viewed as a problem to be avoided, but is used to generate targeted decomposition products and thus a stable protective boundary layer on the lithium metal anode. This approach is currently in research not described.
- polymeric LiPON is usually based on the polymeric polyphosphazene precursor [NPCI 2 ] n .
