Non-aqueous electrolyte battery and method for producing the same

A method for producing a non-aqueous electrolyte battery comprising:

• a positive electrode including a positive collector, a positive active material containing layer formed on the positive collector, and a positive collector exposed portion at a part of the positive collector, on which the positive active material containing layer is not formed;
• a negative electrode including a negative collector and a negative active material containing layer formed on the negative collector;
• and
• a separator provided between the positive electrode and the negative electrode, the method comprising:
• dissolving a heat resistant resin having a heat resistant temperature of 150° C. or more in a solvent to form a solution of said heat resistant resin in said solvent;
• dispersing a thermoplastic resin in said solution in which the heat resistant resin is dissolved to form a slurry;
• and
• applying the slurry to at least one of the positive collector exposed portion, the negative electrode, and the separator, followed by drying,
• wherein an insulating resin film formed of a base substance of a heat resistant resin having a heat resistant temperature of 150° C. or more, the resin film containing a thermoplastic resin therein, is provided at a portion where the positive collector exposed portion and the negative active material containing layer are opposed to each other with the separator positioned therebetween.
