What is the cutoff voltage for lithium-ion batteries?

In this comprehensive guide, we will explore the specifics of cut off voltage for lithium-ion batteries, its implications, and the best practices for managing this vital aspect of battery technology. The cutoff voltage for lithium-ion batteries is typically set between 2.5V and 3.0V per cell.

Do lithium batteries need a safety protection function?

Lithium battery applications are ubiquitous, but they require good management to ensure safe and reliable use, especially to prevent the voltage from dropping below the safety line, which we call over-discharge. This requires all batteries to have a safety protection function, which is low voltage cut-off protection, abbreviated as LVC.

How does a lithium ion battery charge?

During charging, lithium-ion batteries exhibit distinct voltage characteristics that reflect their electrochemical processes. The charging cycle typically follows a constant current-constant voltage (CC-CV) protocol. Initially, the battery voltage rises steadily as current flows into the cell.

Can a lithium ion battery be overcharged?

For most lithium-ion batteries, the charging voltage peaks at 4.2V, while the cutoff voltage during discharge is typically 3.0V. Exceeding these limits can lead to overheating, capacity loss, or even thermal runaway. To avoid overcharging, use chargers specifically designed for your battery type.
