PROBLEM TO BE SOLVED: To provide a lithium secondary battery excellent in charge / discharge characteristics under a high temperature environment and having high safety and reliability. In a secondary power source comprising at least a non-aqueous electrolyte containing a lithium salt, a positive electrode, and a negative electrode, The negative electrode includes a negative electrode active material in which an operating potential of the negative electrode is nobler than 1 V with respect to the potential of metallic lithium, a conductive agent containing coke, and a binder that binds the negative electrode active material and the conductive agent. It is characterized by including. [Selection] Figure 1 |
