Battery materials

Battery materials are the components that store and transfer electrical energy in batteries. Key materials include cathodes (positive electrodes) typically made from lithium, cobalt, or nickel, and anodes (negative electrodes) usually made from graphite or lithium compounds. Electrolytes, which can be liquid, gel, or solid, facilitate the movement of ions between the electrodes during charging and discharging. These materials determine a battery's capacity, energy efficiency, lifespan, and safety. Advances in battery materials are crucial for improving technologies like electric vehicles and renewable energy storage, making them more efficient and sustainable.
