LITHIUM BATTERY SAFETY

Rechargeable lithium batteries are commonly referred to as "lithium-ion" batteries. Single lithium-ion batteries (also referred to as cells) have an operating voltage (V) that ranges from 3.6–4.2V. Lithium ions move from the anode to the cathode during discharge. The ions reverse direction during charging.
