Cylindrical nonaqueous electrolyte battery |
摘要 |
A cylindrical nonaqueous electrolyte secondary battery includes: a wound electrode unit as a wound electrode laminate of belt-like positive and negative electrodes laminated via a separator, the positive electrode including a positive electrode collector and a positive electrode active material layer, and the negative electrode including a negative electrode collector and a negative electrode active material layer; an adhesive member provided to cover the wound electrode laminate at a terminating end portion lying on an outer side of the wound electrode unit; and a battery canister housing the wound electrode unit, the adhesive member including a base material, and an adhesive layer provided on a whole surface or on at least a part of the surface on one side of the base material, and the base material being a mixture of a resin material of high swellability and a resin material of high melting point. |

1. A cylindrical nonaqueous electrolyte secondary battery comprising:
a wound electrode unit as a wound electrode laminate of a belt shaped positive electrode and a belt shaped negative electrode laminated via a separator, the positive electrode including a positive electrode collector and a positive electrode active material layer formed on the positive electrode collector, and the negative electrode including a negative electrode collector and a negative electrode active material layer formed on the negative electrode collector; an adhesive member provided to cover the wound electrode laminate at a terminating end portion that lies on an outer side of the wound electrode unit; and a battery canister that houses the wound electrode unit, the adhesive member including a base material, and an adhesive layer provided on a whole surface or on at least a part of the surface on one side of the base material, and the base material being a mixture of a resin material of high swellability and a resin material of high melting point, wherein of the base material the resin material of high swellability is tetrafluoroethylene-ethylene copolymer and included at 90 wt %, and the resin material of high melting point is polyethylene included at 10 wt %. |
