Lithium Ferro Phosphate LiFePO4 batteries

The rechargeable LiFe battery employs lithium iron phosphate as its cathode and carbon as its anode. The electrolyte salt dissolves in organic compound solvent and the electrolyte system is absorbed by the separators and the plates. All batteries of this type have a special one-way valve to allow the disaggregate-tire solvent gases to escape.


Each individual cell is spiral wound and formed to a prismatic cell. The nominal cell voltage is 3.2V. Four cells are placed in series in order to create 12.8V.To protect the battery from over charging and over discharging the battery is equipped with an internal battery management system (BMS). The BMS also takes care of the balance between the internal cells. To avoid overheating of the battery, a special insertion, called PTC, is added to the electrolyte. This additive neutralizes the electrolyte and disables the battery permanently if the internal temperature exceeds 80C.
