Cathode Materials

Cathode materials are the key substances used in batteries’ positive terminals, where they accept electrons during charging and release them during use. They determine a battery’s capacity, voltage, and overall performance. Common cathode materials include lithium cobalt oxide, lithium iron phosphate, and lithium nickel manganese cobalt oxide, each offering different balances of energy density, safety, and lifespan. Advances in cathode materials are crucial for developing better batteries with higher energy storage, longer life, and improved safety for devices like smartphones, electric vehicles, and renewable energy storage systems.
