A lithium battery including an anode having an active anode material, a cathode having an active cathode material. The cathode material includes lithium nickel cobalt manganese cobalt oxide (NCM). An electrolyte separates the anode and cathode. The electrolyte includes a solvent or solvent mixture and lithium hexafluorophosphate, and a germanium organyl-based electrolyte additive. Also disclosed are uses of the germanium organyl-based electrolyte additive in the lithium battery for enhancing one characteristic selected from the group consisting of reversible capacity, Coulombic efficiency, cyclic stability and combinations thereof.

Lithium battery and use of a germanium organyl-based electrolyte additive as an electrolyte additive therein

A method is provided for operating a lithium ion battery having at least one lithium ion cell and a heating device, the method includes a step of operating the lithium ion battery in a temperature range between 5 and 90° C. The heating device is designed to operate the lithium ion battery in a temperature range between 5 and 90° C. The lithium ion cell includes an anode, a cathode, a separator, a current collector and an electrolyte. The electrolyte can contain LiBOB as the conducting salt and at least one solvent selected from propylene carbonate and ethylene carbonate; or having LiFSI and/or LiDFOB as the conducting salt and at least one solvent selected from glycol ether and/or DMC; or having LiFSI and/or LiTFSI and/or LiDFOB and/or LiTDI as the conducting salt and at least one solvent selected from imidazolium compounds, pyrrolidinium compounds and piperidinium compounds.

Method for operating a lithium ion battery, lithium ion battery, and motor vehicle

A lithium-air battery is provided, which includes a cathode having a gas diffusion layer containing a solid electronically conductive material coated with carbon black, the gas diffusion layer being at least partially filled with gaseous air, a separator having an electronically nonconducting filter material arranged between the anode and the cathode, the filter material being at least partially impregnated with a liquid electrolyte, and an anode containing a material selected from lithium metal, material alloyable with lithium, metal oxide, and mixtures thereof. Methods for making such battery and the use of such battery in a motor vehicle are also provided.

Low-polarization lithium oxygen battery

A lithium-sulfur battery which includes an electrolyte containing lithium-ions, an anode and a cathode containing sulfur. The lithium-sulfur battery also contains a surface layer which is arranged between the anode and the cathode. The lithium-sulfur battery further includes areas on the cathode side which contain polysulfides. The surface layer of the lithium-sulfur battery contains at least one graphene layer which is permeable to lithium ions and impermeable to polysulfides.
