If the amount is less than the above range, it is not enough to suppress the generation of hydrogen gas during overdischarge of the battery.On the other hand, if the amount is more than the above range, the high-rate characteristics, especially the low temperature High rate characteristics in the environment deteriorate, which is not preferable.
- the positive electrode material contains carbon particles.
- carbon particles for example, acetylene black, carbon black, artificial graphite, natural graphite, and the like can be used.
