How long is the service life of lithium batteries or how many times are they charged or discharged?

Small current charging and discharging, or not to recharge the electricity, can extend the life of lithium batteries, good or bad, life is long or short. Generally, the capacity is 80% of the initial capacity after 500 times of full charge.

Lithium-ion battery: It is a secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive and negative electrodes. In the process of charging and discharging, Li + is intercalated and de-embedded between the two electrodes: Li + is de-embedded from the positive electrode while charging, and the negative electrode is in the lithium-rich state after electrolyte intercalation; in the case of discharging, the opposite is true. Batteries generally use materials containing lithium as electrodes, which is the representative of modern high performance batteries.

Lithium batteries are divided into lithium batteries and lithium ion batteries. Mobile phones and laptops use lithium-ion batteries, commonly known as lithium batteries, while real lithium batteries are rarely used in daily electronic products because of their high risk.
