Lithium-ion: Li-ion batteries are rechargeable batteries often used in portable applications, such as smartphones and laptops. Because they have a high energy density and low self-discharge rates, Li-ion batteries have a long shelf life and charge quickly.
As lithium-ion batteries are used, their lifespan gradually decreases, and performance may become noticeable. For example, after extended use of a smartphone, you may observe that the battery no longer lasts as long as it once did, indicating a decline in battery life.
Lithium-ion batteries have specific operating temperature ranges (commonly between -20°C and 60°C) due to the characteristics of their internal chemical materials. Operating outside this range can significantly affect performance.
