摘要:
A battery in which a cathode and an anode are arranged so as to face each other an having a separator in between is provided. The separator is formed from a plurality of laminated microporous membranes and has a film thickness of 10x μm and a piercing strength of 150x gf or more, where 1≦x≦2. The air permeability of one layer among the plurality of microporous membranes is equal to or larger than 10% of the air permeability of the whole separator.
