- Lithium batteries are a type of rechargeable battery that uses lithium ions as the charge carriers. Common lithium battery chemistries ueses lithium iron phosphate (LiFePO4).
- Compared to older rechargeable battery technologies like nickel-cadmium and nickel-metal hydride, lithium-ion batteries have a higher energy density, higher voltage, lower self-discharge rate, and lower maintenance requirements.
- Advantages of lithium-ion batteries include high energy density, low self-discharge, high cell voltage, and low maintenance.
