THIN BATTERY AND BATTERY-MOUNTED DEVICE

摘要

A thin battery including a sheet-like electrode assembly; a non-aqueous electrolyte with which the electrode assembly is impregnated; and a housing in a sealed manner. The electrode assembly includes a pair of first electrodes disposed at outermost sides of the electrode assembly, at least one second electrode disposed between the pair of first electrodes, and a first separator disposed therebetween. The first and second electrodes respectively include first and second current collector sheets and first and second active material layers attached to one surface of the first and second current collector sheets. The first separator is bonded to the first active and second active material layers. Sliding resistance R11 between the first separator and each first active material layer and sliding resistance R12 between the first separator and each second active material layers satisfy:;0.5 N/cm2≦R11
