LFP・LTO・Sodium Batteries
Electronic Materials
LFP Battery (Lithium Iron Phosphate)
A type of lithium battery that uses iron phosphate as the cathode material. Commonly used in electric vehicles (EVs), solar energy storage, and power tools due to its safety, long life, and stability.
LTO Battery (Titanate Lithium Battery)
A lithium battery that uses lithium titanate as the anode material. Known for very fast charging and long cycle life. Used in applications like electric buses, energy storage systems, and specific high-performance devices.
Sodium Battery
A battery that uses sodium ions instead of lithium ions for energy storage. Still in development for large-scale applications like grid energy storage, as it is often cheaper and more abundant than lithium.
Each type of battery has its strengths and is suited for different applications based on energy needs, cost, and safety.
