Ilika plc, which trades on the London Stock Exchange’s AIM market under the ticker AIM: IKA, has officially commissioned its 1.5 megawatt-hour Goliath pilot production line, marking a critical milestone in the scale-up trajectory of its large-format solid-state battery platform. This newly operational, fully automated production facility will support the delivery of first-generation 10 amp-hour P1.5 prototypes and initial quantities of 50 amp-hour P2 battery cells, allowing customers to begin validation testing ahead of full-scale commercialisation.
The announcement, made on October 21, 2025, underscores Ilika plc’s commitment to meeting the rigorous demands of automotive original equipment manufacturers and consumer appliance sectors. The commissioning of the Goliath pilot line was highlighted as part of the company’s long-term plan to transition from prototype development to full licensing revenue streams by establishing a reliable and scalable manufacturing base.
This automated production line enhances Ilika plc’s ability to produce uniform, high-quality battery cells at higher volumes, a key requirement for original equipment manufacturers seeking consistency in performance during testing and qualification stages. By controlling the pilot-scale production internally, Ilika plc has significantly de-risked its roadmap and improved its attractiveness as a technology licensor.
Why is the Goliath pilot line critical for scaling 10Ah and 50Ah solid-state battery prototypes?
The new pilot line solves a long-standing bottleneck for Ilika plc. Before this commissioning, the production of solid-state battery cells was constrained by manual processes that limited volume, consistency, and repeatability. The automated line is designed to address these issues head-on by enabling repeatable manufacturing of 10 amp-hour P1.5 battery prototypes while also supporting early-phase production of 50 amp-hour P2 samples.
This upgrade is critical because commercial customers, particularly in automotive and heavy-duty sectors, typically demand large sample sizes of identical cells for testing across safety, longevity, charge-rate, and temperature-tolerance parameters. Ilika plc can now fulfil these demands, boosting its credibility with potential licensees and industrial partners.
Moreover, this pilot line sets the stage for future large-scale production by allowing Ilika plc to work out process refinements, quality assurance protocols, and supply chain alignment before engaging in industrial-scale outsourcing. By controlling these parameters early, the company ensures that when licensing or partnering with external manufacturers, the transition will be smoother and involve fewer engineering and operational risks.
The milestone also validates Ilika plc’s differentiated go-to-market strategy, which prioritises intellectual property licensing over vertically integrated gigafactory investments. The company aims to scale through partners by licensing its solid-state battery architecture and manufacturing know-how while reserving in-house capacity for R&D, prototype delivery, and process control refinement.
How is Ilika leveraging UKBIC and the PRIMED programme to accelerate A-sample and B-sample readiness?
Ilika plc is not scaling in isolation. Its partnership with the UK Battery Industrialisation Centre (UKBIC) and its participation in the PRIMED programme provide critical external infrastructure and funding support. The PRIMED initiative is a government-backed effort involving stakeholders such as Jaguar Land Rover and the High Speed Sustainable Manufacturing Institute to fast-track commercial viability of emerging propulsion technologies.
As part of this collaborative framework, Ilika plc will begin producing A-samples of its 50 amp-hour solid-state battery cells using UKBIC’s flexible pilot production line. These pre-production volumes will undergo rigorous performance and safety validation by automotive partners. Subject to feedback, B-samples will be manufactured using industrial-scale equipment by licensees aligned with Ilika plc’s intellectual property roadmap.
This external support significantly accelerates Ilika plc’s ability to meet automotive-grade sampling thresholds without overextending capital expenditure. UKBIC Chief Executive Officer Sean Gilgun described Ilika plc as one of the first companies to fully utilise the new pilot line infrastructure, calling the milestone a “confirmation that Ilika has successfully completed the bridge between its own capability and full-scale production.”
This endorsement from UKBIC reinforces Ilika plc’s ability to deliver at scale and underlines the strategic importance of public-private manufacturing partnerships in the United Kingdom’s net-zero battery strategy.
What are the institutional and investor signals following Ilika’s commissioning update?
Investor response to the announcement has so far been cautious but stable. As of market close on October 21, 2025, shares of Ilika plc were trading at GBX 45.00, compared to the previous close of GBX 45.50. The intraday range spanned a high of GBX 45.00 and a low of GBX 45.00, with a bid-offer spread recorded at GBX 44.00 / 46.00.
The flat price movement suggests that the market had partially priced in the pilot line commissioning based on earlier updates in Ilika plc’s fiscal year 2025 guidance and September 2025 PRIMED programme disclosure. That said, the consolidation of support around the GBX 45 mark after previous volatility signals renewed investor confidence as milestones are executed as planned.
Looking at the broader 12-month chart, Ilika plc’s stock performance has followed a pattern of sharp rallies followed by consolidations. A notable spike in February 2025 saw shares briefly touch GBX 52 before correcting in the months that followed. Subsequent recoveries in July and October were largely driven by news flow around prototype development and partner engagement.
Analyst upgrades have yet to surface post-commissioning, but coverage sentiment in recent quarters has generally pointed to a “wait and validate” stance. Many institutional investors appear to be positioning for further upside upon customer feedback from the 10 amp-hour prototype deliveries scheduled for December 2025.
What is Ilika’s dual-product battery strategy and how does Goliath fit into the larger portfolio?
Ilika plc operates a bifurcated product strategy that spans both miniature and large-format energy storage segments. The company’s Stereax product line focuses on microbatteries for medical implants, wireless sensors, and Internet of Things applications. These batteries are prized for their size, longevity, and ability to operate in niche environments such as inside the human body.
The Goliath platform, by contrast, is Ilika plc’s flagship offering for the electric vehicle and cordless consumer appliance markets. It leverages solid-state battery chemistry with ceramic electrolytes to enable safer, higher-energy-density storage with superior thermal stability. The Goliath platform is at the centre of the company’s licensing strategy, targeting Tier-1 automotive suppliers, consumer electronics giants, and industrial device manufacturers.
The dual focus allows Ilika plc to monetise across segments, from low-volume, high-margin medical applications to high-volume, license-led automotive partnerships. The commissioning of the Goliath pilot line brings the large-format arm of the business to parity with Stereax in terms of technical readiness and customer engagement potential.
What is the market outlook for Ilika’s solid-state battery platform heading into 2026?
The rest of the 2025 calendar year represents a pivotal period for Ilika plc. The company is expected to begin deliveries of 10 amp-hour P1.5 prototypes to customers starting December 2025. These units will be used in internal test programmes to assess consistency, performance, and safety. Based on this feedback, 50 amp-hour P2 cells will be released in early 2026, with a view to begin A-sample production soon thereafter.
At a macro level, solid-state battery adoption is picking up momentum globally. Automotive manufacturers such as Toyota Motor Corporation, Volkswagen AG, and Stellantis N.V. have announced plans to integrate solid-state batteries into their vehicles by the late 2020s. Ilika plc, with an operational pilot line, credible partnerships, and a licensing-ready technology stack, is well-positioned to capitalise on this tailwind.
However, challenges remain. The ability to convert prototype deliveries into revenue-generating license agreements is crucial for long-term valuation. Investors will be closely watching Ilika plc’s traction with original equipment manufacturers and the pace at which it can translate technical milestones into commercial contracts.
