How Long Is The Life Of Lithium Batteries?


A lithium battery is a battery that uses lithium metal or lithium alloy as the cathode material and uses a non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, Ms. S. Whittingham proposed and began to research lithium-ion batteries. Because lithium metal has very active chemical properties, the processing, storage and use of lithium metal have high environmental requirements. As a result, lithium batteries have not been used for a long time. With the development of science and technology, the lithium battery has 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 lithium metal and are rechargeable. The fifth generation of rechargeable battery, lithium metal battery, was born in 1996. Its safety, specific capacity, self-discharge rate, performance and price ratio are better than lithium ion battery.

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

Previously, lithium-ion batteries were thought to last only two to three years with 300-500 cycles. Now, the rapid development of lithium-ion batteries has greatly increased their life span.

For example, some car companies can guarantee lifetime lithium batteries. In terms of cycle life, lithium iron phosphate batteries have exceeded 3000-4000 times. Some companies are developing car-grade batteries with a cycle life of 5,000-6,000 cycles.

In the case of energy-storing batteries, cycle life is even higher. Rip Energy, for example, has achieved more than 6,000 times battery life in the energy storage market. In addition, Rip Energy aims to launch batteries with a cycle life of 8,000 this year and 12,000 in the future.
