PURPOSE:To can be suppressed from its production to provide low internal resistance with high battery voltage further with an excellent charge/discharge cycle characteristic. CONSTITUTION:In a lithium secondary battery comprising a positive pole 1, negative pole 2 formed of lithium metal and a nonaqueous electrolyte 3, the negative pole has a lithium ion conductive layer in the surface. As the lithium ion conductive layer, it consists of a solid electrolyte layer 21 or any of amorphous layer, refined crystal grain layer, dissimilar element diffusion layer. The solid electrolyte layer 21 consists of the first additional element of one kind or more selected from, for instance, Li and a group of P, S, Cl, I, Fe, Mn, Mg, to suppress dendrite from its production. |
