Title: NONAQUEOUS ELECTROLYTE SECONDARY CELL
Abstract:
The purpose of the present disclosure is to improve discharge capacity, during low-temperature use, of a nonaqueous electrolyte secondary cell which uses fluoroethylene carbonate. According to one embodiment, a nonaqueous electrolyte secondary cell is provided with a positive electrode which has a positive current collector and a positive combined material layer formed on the positive current collector, a negative electrode which has a negative current collector and a negative combined material layer formed on the negative current collector, and a nonaqueous electrolyte which contains fluoroethylene carbonate. The negative current collector is constituted by an iron-containing copper alloy.
