The global race to lower electric vehicle (EV) costs and decarbonize the battery supply chain has centered on a single, critical manufacturing breakthrough: dry electrode coating for Lithium Iron Phosphate (LFP) batteries. UK-based technology firm Anaphite is now positioned to solve this challenge, securing £1.4 million via an Innovate UK Investor Partnership.
The strategic funding—comprising a £700,000 grant and matching investment from climate VCs Elbow Beach and World Fund—will finance a program dedicated to applying Anaphite’s proprietary Dry Coating Precursor (DCP®) technology to LFP cathodes and graphite anodes.
Success in this endeavor is non-negotiable for the automotive industry, as LFP batteries are forecast to dominate the mass market, commanding over 55% of global cathode demand by 2030. Unlocking efficient LFP manufacturing is critical to meeting ambitious legislative deadlines, including the UK and European bans on new combustion engine vehicles by 2030 and 2035, respectively.
Why Dry Coating is the Battery Industry’s ‘Holy Grail’
The manufacturing process for battery cells is notoriously energy-intensive, with material mixing and electrode coating stages consuming 30% to 40% of the total energy and cost of production.
The Conventional (Wet) Process vs. Dry Coating
| Process | Key Energy Input | Environmental Impact | Cost Efficiency |
|---|---|---|---|
| Wet Coating | Solvent drying (high heat) | Significant CO2 emissions | High material waste |
| Dry Coating | Mechanical/Chemical Pre-mixing | Near-zero solvent emissions | Up to 40% cost reduction |
The Dry Coating approach eliminates the costly and time-consuming solvent-drying step, offering a direct route to transformational cost savings and a reduced carbon footprint for major cell makers and EV Original Equipment Manufacturers (OEMs).
The LFP Challenge: A Nano-Scale Problem
Anaphite has already validated its DCP® technology on Nickel Manganese Cobalt (NMC) cathodes. However, LFP presents unique and highly complex obstacles:
- Particle Size Difference: LFP materials use particles as small as 0.7–3 microns. In contrast, traditional NMC cathodes use larger particles, typically ranging from 3–20 microns.
- Mixing Complexity: The much higher surface area of these micro-fine LFP particles makes homogeneous mixing of conductive carbon and binder materials extremely challenging.
- Unproven at Scale: While the demand for LFP dry coating is high, no commercial-scale technology has yet been proven to overcome these fundamental material science hurdles.
“We’re thrilled to have secured this grant support… This enables us to attack one of the toughest technical challenges in dry coating—successfully manufacturing LFP electrodes,” said Joe Stevenson, CEO of Anaphite. “Once achieved at scale, it will be enormously valuable to the industry.“
Anaphite’s DCP® Technology: The Precursor Solution
Anaphite is leveraging its deep expertise in nanomaterials and dry coating to solve this problem using its proprietary DCP® technology.
Unlike conventional mixing techniques that fail to uniformly distribute the components, Anaphite uses proprietary chemical compositing techniques. This involves:
- Chemical Attachment: Key materials (binders, conductive carbons) are chemically dispersed and attached directly to the active LFP particles.
- Homogeneous Powder: This creates a perfectly engineered, dry composite powder ready for high-throughput roll-to-roll electrode coating.
The project’s successful completion—demonstrating maximum first cycle efficiency and cycle life in a full cell build—will not only validate Anaphite’s approach but also unlock dry coating for a far broader range of mass-market electrode materials.
Strategic Implications for the UK and Global Energy Storage
This investment supports the UK’s burgeoning advanced manufacturing sector, reinforcing the country’s position in the global battery technology landscape.
The benefits extend beyond the automotive sector, significantly impacting the Battery Energy Storage System (BESS) market. LFP is expected to be the most widely used chemistry for BESS capacity added in the UK by 2030.
“The future of driving is electric, so scaling up affordable, low-carbon battery manufacturing is essential,” said Jonathan Pollock, CEO of Elbow Beach, highlighting the macro necessity of the breakthrough. “Anaphite’s technology has the potential to significantly cut both costs and carbon footprint for battery makers and EV manufacturers.”
