How long is the life span of a lithium battery?How many years can lithium-ion batteries usually last?

Lithium battery is a type of lithium metal or lithium alloy as the cathode material, using non-aqueous electrolyte solution battery.Lithium metal batteries were first proposed and studied by GilbertN.Lewis.In the 1970s, M.S.Whittingham proposed and began working on lithium-ion batteries.Because the chemical characteristics of lithium metal are very lively, the processing, preservation 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 battery has 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 they can be charged.The lithium metal battery, the fifth generation of rechargeable batteries, was born in 1996, with better safety, specific capacity, self-discharge rate and performance price ratio than 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 is only two to three years, with about 300-500 cycles.Now, the rapid development of lithium battery, the life span has been greatly enhanced.

For example, some car companies can achieve the lifetime warranty of lithium batteries, cycle life, lithium iron phosphate battery has been in more than 3000-4000 times.Some companies are developing standard batteries with 5,000 to 6,000 cycles.

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