PURPOSE: To concurrently obtain high energy density, high charging/discharging efficiency and a long life by using a mix dispersed with Li or Li alloy or Li- mixed metal in an ion conducting polymer material for a negative electrode. n CONSTITUTION: When lithium or lithium alloy or lithium-mixed metal is dispersed in an ion conducting polymer material, the surface of a negative electrode is not deteriorated, the active material of the negative electrode is dispersed, and the specific surface area is increased. The energy density, cycle life, and charging/discharging efficiency are improved, the negative electrode surface is not deteriorated, a large current can be extracted, and the generation of moss-shaped lithium or dendrites can be prevented. n COPYRIGHT: (C)1991,JPO&Japio |
