FIELD: electrical engineering.
SUBSTANCE: invention relates to a storage battery with non-aqueous electrolyte. According to the invention, the storage battery with non-aqueous electrolyte includes a positive electrode, a negative electrode and a solution of a non-aqueous electrolyte. Positive electrode comprises a layer of active material of the positive electrode. This layer of active material of positive electrode contains trilithium phosphate and as active material of positive electrode complex oxide of lithium and transition metal, which contains at least lithium, nickel, manganese and cobalt. Negative electrode has a coating film on its surface. Nonaqueous electrolyte solution contains lithium fluorosulphonate. Content of trilithyphosphate relative to the active material of the positive electrode is not less than 0.9 wt% and not more than 4.25 wt%. Content of lithium fluorosulphonate in solution of non-aqueous electrolyte is not less than 0.135 wt% and not more than 0.850 wt%.
EFFECT: excellent low-temperature input characteristics after long-term storage at high temperatures.
