LITHIUM-ION BATTERY

A lithium-ion battery, comprising a positive electrode, a negative electrode and a non-aqueous electrolyte. The negative electrode comprises a negative electrode material layer containing a silicon-based material, and a phosphorus-containing inactive material layer is formed on the surface of the negative electrode material layer. The non-aqueous electrolyte includes a lithium salt, an organic solvent and an additive of the compound represented by structural formula 1, where n is 0 or 1, X is selected from formula 2 or formula 3, Rand Rare each independently selected from H, halogen, an unsubstituted or halogen-substituted hydrocarbon group with 1-5 carbon atoms, formula 4, formula 5, and formula 6, and at least one sulfur atom is present in X, Ror R.
