Abstract
A non-aqueous electrolyte battery has a laminate housing encapsulating therein a battery body including an anode, a cathode and an electrolyte. The laminate housing is made of two laminated films which are thermally fused together at the edge portions thereof. The thermally fused edge portions encapsulate therein moisture absorbent, which is separated from the battery body for effectively preventing the ingress of water.
Claims12
A non-aqueous electrolyte battery comprising a battery body having a cathode, an anode and a non-aqueous electrolyte for passing electric current between said cathode and anode, a laminate housing having a thermally fused periphery for encapsulating said battery body within said laminate housing, and a moisture absorbing member disposed along said thermally fused periphery in a spaced relationship with said battery body.
A method for manufacturing a non-aqueous electrolyte battery comprising the steps of:
- sandwiching a battery body including a cathode, an anode and an electrolyte between a pair of laminated films;
- overlapping edge portions of said laminated films together while sandwiching a moisture absorbing member between said overlapped edge portions;
- and
- fusing said overlapped edge portions to form a sealing structure encapsulating therein said moisture member and sealing a laminate housing encapsulating therein said battery body.
A method for manufacturing a non-aqueous electrolyte battery comprising the steps of:
- sandwiching a battery body including a cathode, an anode and an electrolyte between folded parts of a laminated film;
- overlapping edge potions of said folded parts at three sides thereof while sandwiching a moisture absorbing member between said overlapped edge portions of at least one of said three sides;
- and
- fusing said overlapped edge portions to form a sealing structure encapsulating therein said moisture member and sealing a laminate housing encapsulating therein said battery body.
A method for manufacturing a non-aqueous electrolyte battery comprising the steps of:
- sandwiching a battery body including a cathode, an anode and an electrolyte between a pair of laminated films;
- overlapping edge portions of said laminated films together and fusing said overlapped edge portions to form a laminate housing encapsulating therein said battery body;
- extending a moisture absorbing member along said fused overlapped edge portions;
- and
- covering said moisture absorbing member by using a stripe film.
