Ilika

What Ilika does

Ilika plc is a UK-based solid-state battery technology company founded in 2004 as a spin-out from the University of Southampton and listed on the London AIM market under ticker IKA. The company develops two distinct product platforms: Stereax, millimetre-scale miniature solid-state batteries targeting active implantable medical devices, IoT sensors, and wearables; and Goliath, large-format solid-state pouch cells targeting electric vehicles, defence, and industrial applications. Both platforms are built on proprietary oxide electrolyte and silicon anode chemistry with a dendrite-prevention capability that the company claims distinguishes it from competitors including BYD, Toyota, and Samsung. Ilika's Goliath cells target 350 Wh/kg energy density with intrinsic safety validated through nail penetration testing (cells remaining below 80°C).

The company operates an ARM-style IP licensing business model: it designs new solid-state battery concepts, develops market-driven product roadmaps, exemplifies volume manufacturing at pilot level via a 1.5MWh automated line achieving 93% yield, and licenses the technology to manufacturers for high-volume production. Stereax is manufactured under a 10-year licence by Cirtec Medical at its Lowell, Massachusetts facility, with Ilika supplying cathodes from its UK site. Goliath is positioned for licensing to automotive OEMs and tier-1 suppliers, with partnerships including Agratas (Tata Group), UKBIC, Mpac Group, and Comau (Stellantis). Revenue is at an early commercial stage at approximately £1.1 million for FY ending April 2026, with the first commercial Stereax electrode order received in January 2026 and a £214k joint development programme signed with Brompton Bicycles in April 2026 to expand into the e-bike vertical.

Emerging players

• Amprius Technologies: US-listed silicon anode battery manufacturer focused on aviation, defense, and light EV applications. Comparable to Ilika's silicon-anode Goliath chemistry and adjacent in defence applications, though Amprius ships conventional Li-ion cells rather than solid-state.
• StoreDot: Israel-based developer of fast-charging silicon-dominant battery cells targeting EV OEMs. Comparable to Ilika's Goliath on the silicon-anode chemistry angle and EV OEM licensing model, though StoreDot's chemistry is liquid-electrolyte based.
• Enovix Corporation: US-listed 3D silicon-anode lithium-ion battery manufacturer targeting consumer electronics and IoT. Comparable to Ilika's Stereax on the miniature/IoT battery application side and both pursue advanced silicon-anode chemistries, though Enovix uses conventional Li-ion.

Broad incumbents

• CATL: World's largest battery manufacturer and a major competitor pursuing both conventional Li-ion and condensed-matter/solid-state battery development. Relevant as the dominant incumbent whose internal solid-state programme (targeting 2027 production) could materially outpace independent licensors like Ilika.
• Microvast Holdings: US-listed commercial battery manufacturer producing Li-ion cells and packs for commercial vehicles and energy storage. Comparable to Ilika as a broader battery manufacturer with established commercial revenue, though Microvast operates a vertically integrated manufacturing model rather than licensing.
