The improved process, a low-temperature synthesis route, doesn’t rely on high temperatures, which reduces energy consumption and therefore enhances sustainability, while also reducing the the total carbon footprint. It will enable LFP material and cell production in the UK, Europe, and North America at costs competitive with China.
The process has no by-product dependency and delivers high-purity iron phosphate with tightly controlled particle properties.
This represents a real breakthrough because Iron Phosphate is the main precursor used in the production of Lithium Iron Phosphate (LFP) battery materials, and most of the world’s supply of both Iron Phosphate and LFP comes from China, where it is made from by-products from the steel industry and therefore has inherently high levels of impurities. It also has a high carbon footprint, and last year, China introduced export restrictions on key battery cathode active materials including LFP, manufacturing technologies, and cells subject to export licensing and restrictions.
LFP is strategically important because it is widely used in stationary energy storage systems and is taking an increasing share of the global EV battery market.
The wide range of different Iron Phosphate material specifications were successfully manufactured by Integrals Power and subsequently used to develop low-cost Lithium Iron Phosphate cathode materials. All of these have been tested at cell level in partnership with a leading UK university and the results confirm that performance and quality both exceed those of benchmark material samples from China and do so at a cost that is competitive with incumbent Chinese supply on a $/kWh level.
Proving that high-quality, cost-effective manufacturing of Iron Phosphate using raw materials sourced from localised supply chains is key to establishing mass production of LFP cells in the UK, Europe, and North America.
“Almost every LFP battery in use today traces its supply chain back to China” said Integrals Power Founder and CEO, Behnam Hormozi. “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. 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 International Energy Agency’s Global EV Outlook 2025 report stated that in 2024, LFP batteries accounted for more than 10 percent of Europe’s EV battery market, representing a year-on-year growth of 90 percent for two years running. Of these, the IEA said that nearly all were made in China. The IEA highlighted the risk posed by this situation, noting that OEMs in Europe see LFP as a means of reducing cost, yet the Chinese government’s export restrictions on battery materials and technology pose a threat to manufacturing in Europe as long as reliance on China continues unchanged.
Localised supply chains will also become increasingly advantageous to meeting the requirements of EU battery regulations, and compliance with the Rules of Origin requirements that apply to electric vehicles (EV) exported between the EU and the UK from 2027: 55 percent of an EV’s overall value, and 65 percent and 70 percent of the cells and battery pack respectively must be made in the EU or UK in order to avoid 10 percent tariffs.
Grid-scale energy storage systems are even more reliant on LFP: IEA figures show that more than 90 percent of all those made worldwide use this cell chemistry2, making energy security and independence an even more strategically important factor behind the urgent establishment of localised supply chains to supply the batteries that are needed in the smart grids that buffer increasingly large quantities of renewable energy and provide back-up power to high-demand and fast-growing industries including data centres and artificial intelligence.
Integrals Power has also patented a number of innovations for over 20 cathode active materials including LFP, highlighting that far from being a commodity product, this cell chemistry still holds considerable development potential in applications where cost and safety are the most important attributes. Successfully demonstrating that the Iron Phosphate precursors needed to manufacture it can be made and commercialised in the UK further highlights the role that it can play in establishing and growing sovereign capability in this strategically important sector.
Over the coming months, Integrals Power will commence the supply of FP and Lithium Iron Phosphate samples to major OEMs, battery cell manufacturers, and strategic partners as part of structured validation programmes.
These samples will support performance benchmarking across many applications. This validation phase represents a critical step toward broader industrial adoption. Subject to successful customer qualification, Integrals Power will proceed with the next stage of commercial scale-up, expanding precursor and cathode production capacity to support long-term supply agreements and large-volume manufacturing in the UK, Europe, and North America.
