Integrals Power has achieved a remarkable breakthrough in battery technology with their newly developed Lithium Manganese Iron Phosphate (LMFP) cathode active material. This next-generation material boasts an impressive 80% manganese content, elevating the voltage to 4.1V while maintaining a specific capacity of 150 mAh/g. These advancements could potentially increase electric vehicle (EV) range by up to 20%, offering enhanced energy density comparable to more expensive Nickel Cobalt Manganese (NCM) chemistries.
The innovation has been validated by the Graphene Engineering Innovation Centre (GEIC), which tested and assessed battery cells made from Integrals Power’s LMFP material. Produced at the company’s UK facility, this breakthrough demonstrates the scalability of the technology for future series production volumes. This development not only accelerates the creation of high-performance batteries but also contributes to establishing a sustainable domestic supply chain for the UK’s growing battery industry, marking a significant step forward in the development of energy storage solutions.
By resolving this trade-off, the new LMFP cathode material combines the best attributes of Lithium Iron Phosphate (LFP) chemistries—such as low cost, long cycle life, and good low-temperature performance—with an energy density comparable to more expensive Nickel Cobalt Manganese (NCM) chemistries. This advancement could increase the electric vehicle (EV) range by up to 20% or allow battery packs to become smaller and lighter for the same range.
A new LMFP battery material with 80% manganese content—higher than the typical 50–70%—achieves a specific capacity of 150 mAh/g and delivers a voltage of 4.1 V (versus 3.45 V for LFP). The Graphene Engineering Innovation Centre (GEIC) has completed third-party testing on coin cells, and evaluations using EV-representative pouch cells are underway. The material will soon be available for cell suppliers, battery manufacturers, and OEMs to evaluate and benchmark.
Behnam Hormozi, Founder and CEO of Integrals Power, commented, “The challenge that the automotive industry has been trying to overcome for some time is to raise the percentage of manganese in LMFP cells to a high level while retaining the same specific capacity as LFP.
Using traditional methods, the more manganese you add, the more specific capacity drops, which means it can’t deliver a high energy density.
Our proprietary materials and patented production processes have enabled us to overcome this trade-off and increase manganese content to 80 percent, placing us at the cutting edge of LMFP chemistry.
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.”
Nicky Savjani, Applications Manager in Energy at GEIC, stated: “The dedicated team in the GEIC Energy labs provides comprehensive support in battery materials development and evaluation, bridging academic innovations and industry appetite to push next-generation technologies towards commercialization.
Our GEIC Energy facility, combined with its dedicated team of battery engineers, is driving the push for decarbonizing the transport sector and reinforcing the UK’s leadership in developing sustainable battery technologies.
The battery cells we produced using Integral Power’s LMFP materials exhibited competitive specific capacity during testing, highlighting their potential to enhance EV efficiency and reduce costs by increasing range.”
Integrals Power produced the high-performance LMFP cathode materials at its UK facility, showcasing the technology’s scalability for future mass production. Developing such technology domestically is crucial for establishing a sustainable UK battery industry, supporting the 2030 ban on new combustion engine vehicles, and achieving the 2050 net-zero emissions targets.
By sourcing all raw materials from European and North American suppliers, Integrals Power ensures purer, high-performance LFP and LMFP cathode materials with greater energy density compared to Chinese-manufactured materials that currently dominate global production.
