Title: Separator for secondary battery
Inventor: TOYOSHIMA SETSUO
IPC: H01M2/16
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent inner short circuit from being spread to the surrounding, even in the case an inner short circuit occurs by making a thin porous sheet of nonwoven cloth which is made of heat resistant fibers and impregnated with heat resistant resin have a break temperature at a specified temperature or higher and a tensile strength a specified value or higher. SOLUTION: While sandwiching separators 8 between them, sheet-like positive electrodes 2 and sheet-like negative electrodes 3 are reciprocally layered to give a layered body 1 in a battery case. Each positive electrode 2 is produced by applying a positive electrode active material 4 to the both sides of a positive electrode collector 5, and each negative electrode 3 is produced by applying a negative electrode active material 6 to the both sides of a negative electrode collector 7. The separator 8 is made to have 250 deg.C higher or break temperature and 1.0 kg /15 mm width or higher tensile strength. The separator 8 is produced by producing a thin sheet from an ultra thin heat resistant fiber through a paper manufacturing process by a wet-type paper manufacturing machine, impregnating the thin sheet with 10% of higher concentration of heat resistant resin with 100 cp or lower viscosity, and then pressurizing and heating the resultant thin sheet. Consequently, damage of the battery itself and spread of the damage to the peripheral part are suppressed.
