摘要:
There are provided a nonaqueous-type electrolyte solution having high flame retardancy and a good capacity retention rate, and a device comprising the nonaqueous-type electrolyte solution. The nonaqueous-type electrolyte solution is used in a device comprising a positive electrode, a negative electrode and the nonaqueous-type electrolyte solution, and contains a lithium salt and a compound having a phosphazene structure, and further contains 0.05% by mass or more and 12.0% by mass or less of at least one disulfonate ester selected from a cyclic disulfonate ester and a chain disulfonate ester based on the total of the nonaqueous-type electrolyte solution.
