PROBLEM TO BE SOLVED: To provide a lithium secondary battery using a polymer electrolyte, which has high potential and high energy density, and is superior in a cycle characteristic. SOLUTION: This battery is a lithium secondary battery provided with a positive electrode, a negative electrode and an electrolyte. An active material layer containing a compound for storing and eliminate a lithium ion is arranged on a current collector in the positive electrode, an active material layer containing graphite is arranged on a current collector in the negative electrode, the positive active material layer, the negative active material layer and an electrolyte layer are constituted of a gelled polymer holding the electrolyte, and an electron-conductive material of 1-15 pts.wt. with respect to 100 pts.wt. of the active material is contained in the negative active material layer. |
