Positive electrode active material for lithium ion secondary battery |
摘要 |
A positive electrode active material for a lithium ion secondary battery, including lithium-transition metal composite oxide of a layer crystal structure, in which the lithium-transition metal composite oxide contains an element that improves conductivity of electrons in the lithium-transition metal composite oxide. Use of this positive electrode active material can improve cycle characteristics, high rate characteristics and thermal stability of lithium ion secondary batteries. Furthermore, by use of this positive electrode active material, gas generation in batteries can be decreased. |
