NON-AQUEOUS ELECTROLYTE BATTERY

摘要

A non-aqueous electrolyte battery includes an outer package container, a positive electrode housed in the outer package container and having a positive electrode layer containing an active material, a negative electrode housed in the outer package container and having a negative electrode layer containing lithium-titanium oxide, a separator housed in the outer package container and interposed at least between the positive electrode and the negative electrode, and a non-aqueous electrolyte housed in the outer package container. The separator comprises a porous layer made of cellulose, a polyolefin, or a polyamide and an inorganic oxide filler dispersed in the porous layer, and has a porosity of 60 to 80% by volume.
