NONAQUEOUS-ELECTROLYTE SECONDARY BATTERY |
摘要 |
Provided is a nonaqueous electrolyte secondary battery having improved durability properties in terms of cycling, storage and the like. The nonaqueous electrolyte secondary battery comprises a nonaqueous electrolyte solution that contains a lithium salt and a nonaqueous solvent that dissolves the lithium salt, a negative electrode capable of absorbing and releasing lithium ions, and a positive electrode. The negative electrode contains a negative electrode active material made up of graphite particles having a rhombohedral rate ranging from 0% to 35%, and the nonaqueous electrolyte solution contains a compound represented by formula (1). As a result, a nonaqueous electrolyte secondary battery that achieves the above object is provided. |
