How Long Is The Life Of Lithium Batteries? How Many Years Can Lithium Batteries Generally Be Used?

Lithium batteries are a type of batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are superior to those of lithium-ion batteries.

Lithium-ion batteries are now widely used in electric vehicles, energy storage and digital products.

Previously, the market believed that the service life of lithium batteries was only two to three years, and the number of cycles was around 300-500. Now, the fast-developing lithium batteries have greatly enhanced their lifespan.

For example, some car companies can guarantee lifetime lithium batteries. In terms of cycle life, lithium iron phosphate batteries have been over 3000-4000 times. Some companies are developing automotive-grade batteries with a cycle life of 5000-6000 cycles.

In terms of energy storage batteries, the cycle life is even higher.
