Integral Powers presents improved LMFP cell chemistry

The British battery technology company Integrals Power has developed an LMFP material with a high manganese content that could increase the range of electric vehicles by up to 20 per cent.

Integral Powers is a British company based in Milton Keynes, which was founded in 2020. Now the company has announced the successful development of its new cathode active material Lithium Manganese Iron Phosphate for use in batteries, to be used for long-range electric vehicles. The breakthrough could also be applied to reduce battery pack size and weight.

The breakthrough was made by increasing the manganese content to 80 per cent, compared to the 50-70 per cent found in similar batteries on the market. This allowed Integral Powers to achieve a “higher specific capacity of 150mAh/g and operate at a voltage of 4.1V, in contrast to LFP’s 3.45V.”

Third-party verification has been completed for the battery material in coin cells by the Graphene Engineering Innovation Centre, and the process for testing the batteries in an EV-representative pouch cell is already underway.

Behnam Hormozi, Founder and CEO of Integrals Power explained: “With the third-party evaluation from the Energy team at GEIC, we’re proud to have developed a world-class cell material in the UK that can rival the performance of NCM but is more sustainable and more affordable, and will accelerate the transition to e-mobility.”

On LinkedIn, the CEO wrote: “I am pleased to announce that Integrals Power has achieved a significant breakthrough in Lithium Manganese Iron Phosphate (LMFP, 80% Manganese) cathode active materials for battery cells. By leveraging proprietary materials technology and a patented manufacturing process, the company has successfully addressed the typical drop in specific capacity associated with an increase in manganese percentage.”

EV Magazine further points out that the new material may prove a viable competitor for the cathode materials from China: “By sourcing all raw materials from European and North American suppliers, Integrals Power ensures a purer, higher-performing product with greater energy density, providing a competitive alternative to the Chinese-manufactured cathode materials that dominate the global market.”
