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.

General features

  • More than 2000 deep cycles, LiFePO4 offers the lowest life-cycle costs, using a graphite anode.
  • The battery may be installed in any direction, (upside down is not recommended)
  • Excellent high-rate discharge and recharge capabilities
  • One third the weight of an equivalent lead acid battery
  • Long service life in floating application
  • Maintenance free operation
  • Excellent safety
  • Environmental friendly due to the absence of heavy metals
