PURPOSE:To increase charge-discharge capacity, cycle performance, and high temperature stability by using a solution containing dioxolane as a solvent and lithium perchlorate as an electrolyte as an electrolyte of a secondary battery. CONSTITUTION:In a secondary battery having a lithium negative electrode capable of charge-discharge, a positive electrode capable of charge-discharge, and a separator impregnated with an organic electrolyte, a composite obtained by absorbing lithium in a molding of carbon fiber or carbon powder whose lattice facing in X-ray diffraction is 3.38-3.56Angstrom is used as the negative electrode. The organic electrolyte contains lithium perchlorate (LiClO4) as an electrolyte and at least dioxolane as a solvent. Charge-discharge capacity, cycle performance, and high temperature stability are increased. |
