Separator and non-aqueous electrolyte battery
View Patent ↗A separator having a structure in which a resin layer is formed at least on one principal plane of a base material layer, wherein the resin layer has an inorganic substance is provided. A non-aqueous electrolyte battery in which a cathode and an anode are arranged through the separator so as to face each other is also provided.
1. A non-aqueous electrolyte battery in which a cathode and an anode are arranged through a separator so as to face each other,
wherein said separator includes a resin layer formed at least on one principal plane of a base material layer of the separator,
wherein said base material layer of the separator is microporous,
wherein a piercing strength of said separator ranges from 100 to 1000 gf, and
wherein said resin layer includes an inorganic substance, wherein an open circuit voltage in a fully charged state per pair of said cathode and said anode ranges from 4.2 to 4.6 V.
2. The battery according to claim 1 , wherein a particle size of said inorganic substance ranges from 1 nm to 10 μm.
3. The battery according to claim 1 , wherein an air permeability of said separator ranges from 30 sec/100 cc to 1000 sec/100 cc.
4. The battery according to claim 1 , wherein an open circuit voltage in a fully charged state per pair of said cathode and said anode ranges from 4:25 to 4.6 V.
5. The battery according to claim 1 , wherein said base material layer of the separator includes a plurality of layers.
6. The battery according to claim 1 , wherein said resin layer is microporous.
