Lithium secondary battery |
摘要 |
A lithium secondary battery free from problems encountered with a positive electrode active material exhibiting an electrode potential of not lower than 4.5 volts versus Li - a deterioration in performances because of self-discharge with decomposition of the electrolyte. The lithium secondary battery uses a sulfide based lithium ion conductive solid electrolyte as the electrolyte. Thus, a lithium secondary battery with a very low self-discharge tendency, that is, with the decomposition of electrolyte highly controlled, can be obtained even using the positive electrode active material generating a high voltage. |
