About lithium batteries

Lithium battery is the most common type of rechargeable battery, with the advantages of high energy density, low self-discharge rate and long life, so it is widely used in mobile devices, electric vehicles, solar energy storage and other fields. There are various types of lithium batteries, including lithium-ion batteries, lithium polymer batteries, lithium-iron batteries and so on. Lithium-ion battery is currently the most widely used one, and its cathode materials commonly used are ternary materials, lithium cobaltate, lithium iron phosphate, etc. Lithium polymer batteries have higher safety than lithium ion batteries, but lower energy density, mainly used in mobile power, power tools and other fields. Lithium-iron batteries are suitable for electric vehicles, energy storage systems and other fields due to their high safety and high temperature resistance.
