Cathode active material and lithium ion rechargeable battery using the material |
摘要 |
Provided is a lithium ion rechargeable battery less suffering from swelling even when stored at high temperatures. Disclosed are a cathode active material, a cathode for a lithium ion rechargeable battery using the cathode active material, and a lithium ion rechargeable battery using the cathode. The cathode active material includes particles, each of the particles including a cathode material capable of intercalating and deintercalating lithium ions, and a film formed on at least part of surfaces of the particles. The film includes a compound represented by Chemical Formula (1). Examples of the compound represented by Chemical Formula (1) include lithium squarate and dilithium squarate. Preferably, the lithium ion rechargeable battery is a prismatic battery. |
