Claims
- 1. A non-aqueous electrolyte battery comprising:
- a negative electrode of a light metal having an elongated shape elongated in a first direction, said negative electrode having first and second opposed surfaces;
- an elongated separator having first and second opposed surfaces, said first separator surface being disposed on one of said electrode surfaces;
- a positive electrode of elongated shape having first and second opposed surfaces, one of said positive electrode surfaces being disposed against said separator second surface;
- a positive lead extending over at least one of said surfaces of said positive electrode, and being electrically coupled thereto;
- a negative lead being disposed over at least one of said negative electrode surfaces and being electrically coupled thereto;
- first heat resistant insulating member of a material different from said separator disposed over said negative electrode on said second surface opposite substantially only said negative lead and over substantially only said negative lead; and
- second heat resistant insulating member of a material different from said separator disposed substantially only over said positive electrode on said second surface opposite substantially only said positive lead and over said positive lead;
- wherein said positive and negative electrodes, separator, leads, and first and second heat insulating members form an electrode body, said electrode body being spirally wound upon itself, such that said negative and positive leads are disposed opposite said positive and negative electrodes respectively.
- 2. The non-aqueous electrolyte battery according to claim 1 wherein said positive and negative electrode plates have starting ends, said spiral electrode body having a starting portion comprised of said starting ends, at which said electrode plates winding starts, and wherein both surfaces of the starting portion are covered with a second heat resisting insulating member of a material different from said separator.
- 3. The non-aqueous electrolyte battery according to claim 1 wherein said first heat insulating member is comprised of two sheets.
- 4. The non-aqueous electrolyte battery according to claim 1 wherein said first heat insulating member is a folded sheet having a U-shape.
- 5. The non-aqueous electrolyte battery according to claim 2 wherein said second heat insulating member is comprised of two sheets.
- 6. The non-aqueous electrolyte battery according to claim 2 wherein said second heat insulating member is a folded sheet having a U-shape.
- 7. The non-aqueous electrolyte battery according to claim 2 wherein said second heat insulating member has a columnar shape having a side surface and including a groove therein, said starting portion of said winding being disposed within said groove such that said separator and electrodes starting portion are disposed in said groove.
