摘要:
A non-aqueous electrolyte secondary battery is composed of a positive electrode containing a positive electrode active material capable of storing and releasing lithium ion, a negative electrode containing a negative electrode active material capable of storing and releasing lithium ion, and a non-aqueous electrolyte. The negative electrode active material contains a first material of a graphite material and a second material of a complex in which graphite material and silicon or silicon composite are coated with amorphous carbon material, and a cyclic carbonic acid ester derivative having fluoride atom and a sulfur-containing composite having cyclic structure are added to the non-aqueous electrolyte.
