RESIN COMPOSITION FOR LITHIUM ION CELL POSITIVE ELECTRODE |
| 摘要 |
Disclosed is a resin composition for positive electrodes of lithium ion cells, which imparts strong adhesiveness and electrolyte injectability and shows good discharge and charge characteristics and input-output characteristics with smaller amount of a binder. The resin composition for positive electrodes of lithium ion cells is a resin composition for positive electrodes of lithium ion cells, which comprises a polyimide precursor whose average thermal linear expansion coefficient in the range of 20° C. to 200° C. after being imidized is 3 to 50 ppm, and/or a polyimide whose average thermal linear expansion coefficient in the range of 20° C. to 200° C. is 3 to 50 ppm, and a positive electrode active compound, wherein the positive electrode active compound is one obtained by coating the surface of a composite oxide containing lithium with a lithium ion conductive material. |
