The present invention provides an electrode material and production method thereof. The electrode material comprises: an electrode active material; and an elastic layer coated on the electrode active material, wherein the elastic layer comprises the elements of C, H, O, N, S and the electrode material has the characteristic peaks at mass-to-charge ratio (m/z) 261±0.5, (m/z) 155±0.5, (m/z) 80±0.5, (m/z) 32±0.5, and (m/z) 14±0.5 using TOF-SIMS with the primary ion of Bi.

Electrode material and production method and application thereof

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.
