UK battery technology company Integrals Power has developed a low-temperature iron phosphate precursor manufacturing process using locally sourced materials. Cell-level testing confirms performance exceeding Chinese benchmarks at competitive cost, offering a pathway for LFP battery production in the UK, Europe, and North America independent of Chinese supply chains.
Milton Keynes-based Integrals Power has developed a manufacturing process for iron phosphate (FP) precursor material that it says can underpin competitive lithium iron phosphate (LFP) battery production in the UK, Europe, and North America without relying on Chinese supply chains.
The company’s low-temperature synthesis route produces high-purity iron phosphate with controlled particle properties while cutting energy consumption and CO2 output compared with conventional methods. Crucially, the process uses locally sourced raw materials and does not depend on steel industry by-products — the feedstock typically used by Chinese producers, which Integrals Power says carries inherently high impurity levels and a larger carbon footprint.
Cell-level testing carried out with a UK university partner confirmed that LFP cathode materials made from the company’s iron phosphate exceeded the performance and quality of benchmark Chinese samples, while remaining cost-competitive on a dollar-per-kilowatt-hour basis.
“Almost every LFP battery in use today traces its supply chain back to China. We’ve spent years developing a way to change that — and now we can show it works, it’s cost-competitive, and it’s ready to scale,” says Behnam Hormozi, founder and chief executive of Integrals Power. “By rethinking the chemistry from first principles, we’ve developed a manufacturing process for the Iron Phosphate precursor that is cleaner, more energy-efficient and — as our testing confirms — produces a better material. It’s a breakthrough that represents the foundations on which a viable Western LFP supply chain can be built, and for EVs, grid energy storage, and the data centres that power AI, this is of paramount importance.”
The timing is notable. China introduced export restrictions last year on LFP cathode active materials, manufacturing technologies, and cells. Meanwhile, the International Energy Agency’s Global EV Outlook 2025 report found that LFP batteries accounted for more than 10% of Europe’s EV battery market in 2024, with year-on-year growth of 90% for two consecutive years — nearly all sourced from China.
Localized production also has trade compliance implications. From 2027, Rules of Origin requirements for EVs traded between the EU and the UK will mandate that 55% of a vehicle’s overall value, 65% of its cells, and 70% of its battery pack are made in the EU or UK to avoid 10% tariffs.
Grid-scale energy storage adds further urgency: IEA figures indicate that more than 90% of stationary storage systems worldwide use LFP chemistry.
Integrals Power has also patented innovations across more than 20 cathode active materials including LFP. Over the coming months, the company will begin supplying FP and LFP samples to OEMs, cell manufacturers, and strategic partners as part of structured validation programs. Subject to successful qualification, the company plans to scale production capacity to support long-term supply agreements and large-volume manufacturing across the UK, Europe, and North America.
