Abstract
A lithium secondary battery provided by this invention has electrodes and configured in a structure in which active material layers, including active materials and binders, are held by collectors. The active material of at least one of the positive electrode and the negative electrode of the electrodes is formed from a metal compound which stores and releases lithium ions through conversion reactions. The lithium secondary battery includes a polyimide-base resin as a binder.
