Positive electrode for lithium ion secondary battery and lithium ion secondary battery including same |
摘要 |
A rechargeable lithium ion battery including a positive electrode a positive active material and including a negative electrode having a negative active material. The positive active material includes a lithium-manganese-based compound core and a heat resistant polymer disposed on the lithium-manganese-based compound core. The heat resistant polymer has a glass transition temperature (Tg) ranging from about 80 to about 400° C. Alternatively, the positive active material may include a lithium-manganese-based compound core and an inorganic metal compound as well as the heat resistant polymer with a glass transition temperature (Tg) ranging from about 80 to about 400° C. disposed on the lithium-manganese-based compound core. |
