Why is current important when charging a lithium ion battery?

When charging and discharging lithium-ion batteries, the current is an important factor to consider. The current flowing into the battery during the charging process determines how quickly the battery charges. A higher current means a faster charge time, while a lower current means a slower charge time.

When does a lithium ion battery charge end?

Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging

What happens if you charge a lithium ion battery below voltage?

Going below this voltage can damage the battery.
