Abstract
A gelled polymer electrolyte having a high mechanical strength and a high ion conductivity and a lithium polymer battery using the same electrolyte are disclosed. The gelled polymer electrolyte comprises a polymer alloy and an organic electrolyte solution, wherein the polymer alloy includes a polymer which is hardly soluble in the organic electrolyte solution and another polymer which is soluble in the organic electrolyte solution. The lithium polymer battery comprises a negative electrode including metallic lithium, a lithium alloy, carbon or an inorganic compound, and a positive electrode including an active material of a metal oxide capable of intercalating and deintercalating lithium in a reversible manner, such as LiCoO.sub.2, LiNiO.sub.2 or the like, and the gelled polymer electrolyte placed between both electrodes.
