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

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
