A Lithium-ion battery is a rechargeable battery type in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. The three primary functional components of a Lithium-ion battery are the positive & negative electrodes and electrolyte.
Lithium-ion offers the highest energy storage to smallest weight/volume ratio of any kind of today’s commercially available battery. Very fast recharge and longer life are also very compelling arguments for this battery type.
Exide Li-Ion battery uses lithium iron phosphate (or LiFePO4), the best choice for top safety & life span with good power density (CCA).
LiFePO4 batteries benefits include:
- Very constant discharge voltage. Voltage stays close to 3.2V during discharge until the cell is exhausted. This allows the cell to deliver virtually full power until it is discharged
- Longer cycle life than other lithium-ion approaches
- Higher current or peak-power ratings than other lithium-ion types
- Very low self-discharge
- High thermal and chemical stability, which improves battery safety
