Lithium Manganese Iron Phosphate

Abbreviated as LMFP, Lithium Manganese Iron Phosphate brings a lot of the advantages of LFP and improves on the energy density.

  • LiMnxFe1−xPO4
  • 15 to 20% higher energy density than LFP
    • Approximately 0.5V increase over LFP and hence energy increase
  • Maximum theoretical cell level energy density ~230Wh/kg
  • manganese is not a rare metal, global manganese ore resources are very rich
  • Cell voltages with Graphite Anode
    • 4.25V maximum, 3.75V nominal, 2.5V minimum
  • Electrodes
    • Cathode is aluminium
    • Anode is copper


  • low electronic conductivity
  • LMFP sees a 5 to 10% cost increase over LFP
  • low rate performance

Gotion L600 Astroinno

The Gotion L600 Astroinno is an Lithium Manganese Iron Phosphate (LMFP) based cell chemistry.

  • 5% lower cost than a conventional LFP
  • 20-25% less expensive than cells NMC
  • 240Wh/kg and 525Wh/litre
