Why does the lithium battery decay?

Why is the capacity of lithium-ion batteries attenuated?

From pure electric vehicles to electronic products such as computers and mobile phones, the battery life has always been highly concerned by consumers. Even the recent Samsung note7 explosion incident has been blamed by some experts for the developer's excessive pursuit of battery life and neglected the safety risks of the battery. The company that suffers from the battery is not only Samsung. Recently, the battery of the Microsoft SurfacePro3 has also had problems. Some users have reported that the SurfacePro3 equipped with the LGC battery has been seriously shrunk in the follow-up time of the upgrade.

Why is the capacity of lithium-ion batteries attenuated?

Lithium-ion battery is the fastest growing secondary battery after cadmium-nickel battery and hydrogen-nickel battery. The application of lithium-ion battery depends largely on the stability of its charge-discharge cycle. Like other secondary batteries, lithium-ion battery capacity decay is inevitable during the cycle.
