Abstract
A main object of the invention is to provide a lithium secondary cell which experiences minimal capacity deterioration upon repetitive charge-discharge cycles. The lithium secondary cell of the invention is characterized in that a negative and/or positive electrode material is bonded to a current collector surface by a binder containing a crosslinked polymer or formed by coating to a current collector a composition comprising an active material and a polymer binder containing a fluorinated polymer which is curable upon exposure to radiation, followed by radiation curing treatment.
