Integrals Power’s latest rich‑manganese Lithium Manganese Iron Phosphate (LMFP) technology has achieved a significant milestone, with independent testing confirming impressive durability and cold‑weather performance.
The company’s UK‑developed cathode active material, produced using an 80% manganese formulation, has now surpassed 1,500 charge–discharge cycles in ongoing assessments carried out by QinetiQ. At this stage, the pouch cell retains close to 80% of its original capacity, reinforcing the material’s suitability for long‑life battery applications across demanding sectors.
Further evaluation by Cranfield University has demonstrated the LMFP’s resilience in extreme low temperatures. Cells from the same production batch retained 85% capacity at –25ºC and 68% at –30ºC, outperforming typical LFP and LMFP chemistries, which often fall to around 50% and 40% respectively. This level of cold‑weather capability is particularly valuable for electric vehicles, maritime systems, aerospace platforms and defence equipment operating in harsh environments.
Alongside durability and temperature stability, the material offers a lower‑cost, lower‑toxicity alternative to NMC chemistries, while reducing reliance on critical minerals and delivering a smaller carbon footprint. Its higher energy density compared with LFP further strengthens its commercial potential.
Founder and CEO Behnam Hormozi said: “Independent, third-party testing by industry experts is a cornerstone of our business, and these latest results from QinetiQ and the University of Cranfield are invaluable in providing trusted and credible data to our customers around the world. The results prove that batteries made from our LMFP material can last longer, and perform better in sub-zero conditions.”
