Abstract
In a lithium secondary battery comprising a chargeable and dischargeable positive electrode, a chargeable and dischargeable negative electrode and an electrolyte, wherein at least one of the positive electrode and the negative electrode comprises a lithium-containing halide having a spinel structure or spinel analogous structure, the lithium-containing halide having a spinel structure or spinel analogous structure having a high ion bonding property is dissolved into an electrolyte obtained by dissolving a salt into an organic solvent. In the secondary battery of the present invention, since a lithium ion conductive inorganic solid electrolyte is used as an electrolyte, there can be obtained a chargeable and dischargeable lithium battery in which at least one of a positive electrode and a negative electrode comprises a lithium-containing halide having a spinel structure or a spinel analogous structure.
