Anaphite, a Bristol-based battery know-how firm, has secured €1.6 million (£1.4 million) in a Sequence A follow-on spherical by the Innovate UK Investor Partnership Programme.
Half of the funding comes from Innovate UK’s Clear Power and Local weather Applied sciences competitors, with the opposite half offered by aligned funding from climate-focused enterprise capital funds Elbow Seaside and World Fund. The capital will help the growth of Anaphite’s Dry Coating Precursor (DCP®) know-how platform past NMC cathodes to allow high-throughput dry coating of lithium iron phosphate (LFP) cathodes and graphite anodes.
LFP cathodes have change into more and more aggressive in mainstream electrical autos in recent times, regardless of having decrease power density than NMC supplies. Nonetheless, manufacturing LFP cathodes stays considerably extra energy-intensive, requiring greater than twice the power per kWh of battery cells produced in contrast with NMC cathodes utilizing medium-to-high nickel content material. Materials mixing and electrode coating account for 30–40% of whole cell manufacturing power and price, making course of optimisation a key lever for lowering each price and carbon depth.
With LFP forecast to account for greater than 55% of worldwide cathode demand by 2030, demand for applied sciences that allow dependable, high-yield dry coating is rising. But dry coating LFP cathodes is more difficult than NMC, with no commercial-scale answer confirmed to this point. To satisfy rising EV demand, in addition to regulatory milestones together with the 2030 and 2035 bans on new combustion engine autos within the UK and EU, scalable manufacturing processes are urgently wanted.
Anaphite goals to handle these challenges by making use of its dry coating experience and nanomaterials functionality to LFP electrode formulations. The corporate has already demonstrated the efficiency of its dry coating know-how on NMC cathodes. Its DCP® platform makes use of proprietary chemical compositing methods to disperse difficult-to-mix supplies similar to binders and conductive carbons, attaching them to energetic materials particles to create homogenous dry composite powders. This method is meant to beat the constraints of present mixing strategies, which have confirmed insufficient for LFP dry coating.
Anaphite’s CEO Joe Stevenson says: “We’re thrilled to have secured this grant help from Innovate UK and the matching funding from Elbow Seaside, World Fund and different Anaphite traders. This permits us to assault one of many hardest technical challenges in dry coating – efficiently manufacturing LFP electrodes. As soon as achieved at scale, it will likely be enormously invaluable to the trade. Anaphite’s DCP® know-how has been profitable with NMC dry coating formulations, and we’re assured it may be utilized to LFP, to additional increase the fee and carbon emission financial savings for OEMs.”
One of many main hurdles with LFP formulations is particle measurement. The newest technology of LFP (Gen IV) has particles ranging between 0.7 and three microns, in contrast with 3 to twenty microns for NMC. The considerably increased floor space of LFP particles introduces challenges in reaching uniform mixing and constant dry movie formation.
Craig Douglas, Accomplice, World Fund, feedback: “Anaphite’s know-how is broadly relevant throughout next-generation and established battery applied sciences alike. This funding will allow the corporate to considerably develop its business capabilities, accelerating the scale-up of its manufacturing processes and driving down manufacturing prices for the worldwide battery trade.”
Key outcomes anticipated from the venture embrace profitable roll-to-roll manufacturing of dry-coated LFP cathodes and graphite anodes, adopted by full cell builds for testing. Demonstrating excessive first-cycle effectivity and robust cycle life will validate the applicability of Anaphite’s know-how to LFP and graphite formulations. This might open the door to dry coating throughout a wider vary of mass-market electrode supplies and strengthen ongoing collaborations with world OEMs searching for to scale back each price and environmental impression in battery cell manufacturing.
The venture aligns with the UK Authorities’s Superior Manufacturing Plan, which identifies batteries and automotive as precedence sectors for industrial progress. Additionally it is anticipated to help additional growth of the BESS sector, which is forecast to account for many new power storage capability added within the UK by 2030, with LFP anticipated to change into the dominant chemistry.
