Lithium iron phosphate (LiFePO) - Battery

Lithium iron phosphate (LiFePO)

Lithium-iron-phosphate batteries are a further development of lithium-ion technology with a cell voltage of 3.2 and 3.3 V. The negative electrode is made of lithium iron phosphate instead of lithium cobalt oxide. The positive electrode is made of graphite or else made of hard plastic with lithium. The basic advantages over lithium-ion batteries are a prolonged service life as well as improved temperature stability.

Characteristics of lithium-iron-phosphate batteries:
  • Proven technology
  • Nominal cell voltage 3.2 V
  • At 80% capacity utilization, around 3000 - 4000 load cycles
  • Gross around 12 kg/kWh, at 80% utilization 15 kg/kWh
  • Charge currents during discharging: 2C (medium loadable)
  • Charge currents during charging: 1C
  • Temperature range during discharging: -25 to +60 °C
  • Temperature range during charging: 0 to +50 °C; with derating at the limits
  • Costs: Life-cycle costs inexpensive to medium, investment medium
Application examples of lithium-iron-phosphate batteries:
  • Robust traction battery, if the required C rates (charge currents) are not too high
Advantages of lithium-iron-phosphate batteries:
  • The power density of 3000 W/kg is higher than that of Li-ion batteries, resulting in a higher loading capacity
  • Electrical efficiency for total cycle > 91%
  • High level of safety: Solid electrolyte and cell chemistry prevent thermal penetration (fire or explosion)
  • High impulse load up to 40 °C
  • Comparatively insensitive to storage temperature
  • Low self-discharge: 3-5%/month
  • Long service life and low operating costs due to high cycle durability
  • Cobalt-free, thereby improving environmental compatibility
  • Flat voltage profile during charging and discharging
Disadvantages of lithium-iron-phosphate batteries:
  • Safety circuits are necessary to ensure safe operation
  • Flat voltage curve makes determination of the charge state more difficult
