Abstract
There is disclosed a non-aqueous-electrolyte secondary battery comprising a positive electrode including a material capable of reversibly absorbing and releasing lithium, a negative electrode, a non-aqueous electrolyte containing a lithium salt, and a separator of the secondary battery the negative electrode comprises a material mainly comprising an amorphous chalcogen compound and/or an amorphous oxide including three or more atoms selected from the group consisting of Groups 1, 2, 13, 14, and 15 of the Periodic Table, and the said non-aqueous-electrolyte contains at least one N-containing organic compound. This non-aqueous electrolyte secondary battery has excellent charge and discharge characteristics, and its decrease of discharge capacity due to repeated charging/discharging is small.
