Abstract
A lithium secondary battery 100 provided by this invention has electrodes 30 and 40 configured in a structure in which active material layers 34 and 44, including active materials and binders, are held by collectors 32 and 42. The active material of at least one of the positive electrode 30 and the negative electrode 40 of the electrodes is formed from a metal compound which stores and releases lithium ions through conversion reactions. The lithium secondary battery 100 includes a polyimide-base resin as a binder.
