How Many Years Is The Lithium Battery Life Cycle?
- Apr 25, 2018 -

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

Lithium batteries can be divided into two types: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation lithium battery of rechargeable battery was born in 1996. Its safety, specific capacity, self-discharge rate and performance-cost ratio,Lithium metal batteries are all superior to lithium-ion batteries. Because of its own high-tech requirements, companies in only a few countries are now producing such lithium metal batteries.
Battery Life

So many suers want to know How many years is the lithium battery life cycle?

Experts feeback :Lithium-ion battery can only charge and discharge 500 times.

Does Lithium-ion battery can only charge and discharge 500 times?

I believe most consumers have heard that lithium battery life is "500 times", 500 times charge and discharge, more than this number, the battery "end of life", and many friends in order to be able to extend the life of the battery, each time Is the battery charged only when it is fully depleted, does this really extend the life of the battery? the answer is negative. Lithium battery life is "500 times", not referring to the number of charges, but a charge and discharge cycle.

A charge cycle means that the battery's full charge to empty, and then empty to full, is not the same as charging a battery. For example, a piece of lithium used only half of the electricity on the first day, and then it was fully charged. If this is the case on the second day, it will be charged in half and charged twice in total. This can only be counted as one charge cycle, not two. Therefore, it may take several times to complete a cycle. Each time a charge cycle is completed, the battery capacity is reduced by a little. However, the amount of power reduction is very small. After a high-quality battery has been charged for many cycles, it will still retain 80% of the original capacity. Many lithium-powered products will still be used after two to three years. Of course, the lithium battery life still needs to be replaced after the end.

The so-called 500 times means that the manufacturer has achieved about 625 times of recharge times at a constant discharge depth (such as 80%) and reached 500 charging cycles.

(80% * 625 = 500) (ignoring lithium battery capacity and other factors)

Due to various effects of actual life, especially the depth of discharge during charging is not constant, "500 charging cycles" can only serve as a reference battery life.A "lithium battery" is a type of battery that uses a lithium metal or a lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution.

A charge cycle means that the battery's full charge to empty, and then empty to full, it is not the same as charging a battery. For example, a piece of lithium battery is used only half of the electricity on the first day, and then it was fully charged. If it is used same on the second day, it will be charged in half and charged twice totally. This can only be counted as one charge cycle, not two. Therefore, it may take several times to complete a cycle. Each time a charge cycle is completed, the battery capacity is reduced by a little. However, the amount of power reduction is very small. After a high-quality battery has been charged for many cycles, it will still retain 80% of the original capacity. Many lithium-powered products will still be used after two to three years. Of course, the lithium battery life still needs to be replaced on the end.

Due to various effects of actual life, especially the depth of discharge during charging is not constant, "500 charging cycles" can only serve as a reference battery life.

And GSLIBATT lithium batteries adopt high density negative electrode material,so our life cycle is high ,and safe.

Our lifepo4 battery life cycle could more than 2500, so it is same meaning.
