Ilika plc Announces Positive Feedback on Safety Testing of Goliath Cells by UK Defence Agency Ilika plc announced it has received positive feedback from a UK defence agency on safety tests of its batteries under battlefield conditions, highlighting the potential of the technology for use in high-risk, mission-critical environments where safety is paramount. In December 2025, Ilika delivered prototypes to customers across multiple industries, including an agency which advises the UK Ministry of Defence. The prototypes were subjected to firing range tests, which showed that: A Goliath 10Ah cell could survive a single shot before a thermal event was triggered by a second one; Low state-of-charge 10Ah Goliath cells did not show a thermal event; A Goliath cell showed a delayed reaction before entering thermal runaway; A Goliath cell reached a lower thermal runaway temperature than conventional Nickel Cobalt Aluminium ("NCA") lithium-ion cells; Despite Goliath 10Ah cells storing 3x the energy of conventional NCA cells being tested under equivalent conditions in the same trial, the Goliath cells had a similar thermal response. This independent validation follows the delivery of Goliath prototypes to multiple customers in December 2025 and supports Ilika's ongoing engagement with partners evaluating safety-critical applications. Under certain abuse conditions, conventional lithium-ion batteries can enter a state of thermal runaway, which is a chain reaction in which the battery temperature rises uncontrollably, leading to a fire or explosion.

Ilika plc Announces Goliath Battery Achieves Scale-Up Milestone Ilika plc confirmed superior performance of its Goliath batteries manufactured via an industrially scaled process at The UK Battery Industrialisation Centre. This further underpins confidence that the battery is on track on its route to market, reducing costs, increasing range and reducing charging time of electric vehicles. This follows Ilika's 5 February 2025 announcement reporting large-scale preparation of the Goliath electrolyte and successful coating of its proprietary composite electrolyte-electrode. Ilika has used these materials to build a batch of solid state 10Ah prototype cells. After analysis of the performance of these cells, Ilika can verify that the scaled manufacturing process at UKBIC resulted in a higher manufacturing yield and has delivered cells superior in performance to those made with similar starting materials on Ilika's pilot line. This confirms that the tolerances of industrial equipment will unlock further improvements to Goliath SSB technology. The increase in manufacturing yield resulted from enhanced handling robustness after coating and fewer defects from the drying process. The superior performance was measured as higher battery capacity under rapid charging protocols. Ilika announced in October 2023 receipt of grant support from the Automotive Transformation Fund ('ATF') through an 18-month, £2.7 million collaboration programme, codenamed Project SiSTEM, to scale up Ilika's Goliath solid-state battery production capability. Via the programme, Ilika partnered with Mpac Group plc ('Mpac') global supplier of packaging and assembly automation, UKBIC and Agratas, Tata Group's global battery business. Through this collaboration, UKBIC and Ilika have carried out physical trials to demonstrate preparation and roll-to-roll coating of its proprietary solid state materials. The planned trials are now complete and the cell test data announced provide evidence that Ilika's approach to large format solid-state battery manufacture can be carried out with the types of mixing and coating equipment widely used in existing gigafactories. In addition, the trials show that the quality of product made on large scale equipment actually improves with scale. Project SiSTEM has now successfully completed, with the associated delivery of the 1.5MWh solid-state battery assembly line from Mpac planned for second half Current Year 2025. The assembly line will be capable of producing Ilika's Goliath prototype large-format pouch cells to automotive original equipment manufacturers and Tier 1 suppliers, in line with planned delivery timeline.

Ilika plc Announces Goliath Development Progress Ilika announced it has successfully prototyped a 50Ah Goliath electric vehicle (EV) battery, which is a key targeted outcome of the Faraday Battery Challenge HISTORY programme. The 50Ah prototype is the capacity of battery Ilika will now optimise for its minimum viable product for EVs. The battery is expected to reduce costs, increase the range of EVs and reduce their charging time. This successful prototype build follows the recently announced demonstration of manufacturing in a giga-scale factory setting, using industry standard equipment at the UK Battery Industrialisation Centre, marking the latest step towards commercialisation. It builds on the progress made in 2024 which included the start of commercial testing, shipping of the first batch of prototype Goliath batteries to customers, and the release of validated safety data. Ilika will now undertake further optimisation based on the initial test results, before commencing a build and test programme in H2 CY 2025. The Company is targeting an initial release of batteries of this capacity for partner evaluation from the end of CY 2025. Tillkännagivande • Jan 09
Ilika plc Announces the Production of Stereax Batteries for Process Qualification Now Commence Ilika announced that the production of Stereax batteries for process qualification has now commenced. In July 2024, Ilika confirmed that installation of its key equipment had been substantially completed in Cirtec Medical's facility in Lowell, MA, USA. Ilika can now confirm its equipment has been commissioned and successfully passed its User Acceptance Tests (UATs). These production tools include layer deposition machines as well as alignment and patterning machines. This final stage in the commissioning of Stereax new manufacturing facilities means that both Cirtec and Ilika are now satisfied that the equipment meets its requirement for the start of production transfer. To support equipment commissioning, since June 2024, Ilika has delivered a series of batches of cathode-coated wafers to Cirtec, for further processing and verification of subsequent process steps. Process qualification has the aim of refining and tuning the process equipment to achieve specified product performance in preparation for the start of product manufacturing. Ilika currently retains and will operate part of the production equipment in the UK, including that for cathode deposition and cell formation and testing. In August 2023, Ilika and Cirtec Medical announced that they had concluded contractual negotiations by signing a ten-year manufacturing licence to produce the Stereax range of mm-scale batteries at Cirtec's facility in Lowell. This partnership will reinforce Cirtec's ongoing activities in system level miniaturisation for the medical device industry, whilst Ilika will focus on advanced technology development and IP licensing in support of Cirtec's manufacturing and commercialisation activities.

Ilika plc Announces Goliath D6 Milestone Reaches Ramping Up Ev Battery Capacity Ilika announced that it has successfully reached its D6 milestone by testing 10Ah cells in its Goliath solid state batteries for electric vehicles. The systematic testing to industry standards demonstrates the increased capacity of its cells as it systematically moves along its development roadmap for customers. Building and successfully testing these larger 10Ah cells follows on from the announcement last month on 3 October 2024 of compelling safety data from the testing of its Goliath D5 prototypes. Ilika is now progressing with development towards a D7 design freeze, which it expects to achieve in first quarter 2025. The D7 design freeze will form the basis of a release of 10Ah prototype cells to customers, called the P1.5 prototypes, which will be an upgrade on the 2Ah P1 prototypes released in July 2024. This intermediate P1.5 prototype will address automotive OEM requests for a further proof-point of the technology, as Goliath scales up beyond the capacity of cells released by some competitors. The timing of the P1.5 release will be driven by completion of testing of a batch of batteries based on the D7 design, by second quarter 2025. The 2025 development roadmap will then extend to D8 design freeze, which is also expected in first quarter 2025, and then to the crucial Minimum Viable Product ("MVP") stage, targeted for the end of 2025. Ilika's Goliath MVP, or 50Ah P2 prototypes, will underpin revenue generating licensing opportunities. The modelling of a Goliath-based battery pack for EVs is underway by UK company Balance Batteries, that capitalises on the superior safety, high energy density and fast charging features of the Goliath cells. Early results show that the weight of the battery pack can be reduced materially by up to 100 kg on the basis of Goliath's benefits, compared to a current SUV lithium-ion model of the same energy. This reduction in weight translates into increased driving range on the same level of battery charge and reduced vehicle cost. Tillkännagivande • Nov 15

Ilika plc Completes Testing of Its Goliath D5 Prototypes Ilika announces it has completed testing of its Goliath D5 prototypes, thereby further confirming the safety characteristics of Ilika's batteries. The testing reconfirmed the benefits of Goliath relative to lithium-ion equivalent across a number of key variables - reinforcing the fact that Ilika's cells have the potential to provide electric vehicles (EV) with lighter, safer, cheaper batteries with longer ranges and faster charging capabilities. The D5 prototype is designed to build on the characteristics of the D4 data point achieved in 2023. This was achieved by optimising the cell architecture to increase Goliath's unique safety value proposition without compromising cell energy density. The key findings from the testing programme provide further validation along the development curve to D8 and MVP samples during calendar year 2025: Exceptional results from the nail penetration test carried out by University College London as part of the Faraday Institution funded Safebatt Industrial Sprint programme. The results classify puncturing the D5 prototypes as a EUCAR 3 hazard event, with no leakage, no venting, no fire or flame, no rupture and no explosion. In contrast, puncturing the benchmark lithium-ion battery resulted in a higher EUCAR 6 event, i.e. a rupture accompanied by flying parts of the active mass, fire and flame. Components confirmed to be non-flammable by DEKRA, the world's largest independent, non-listed expert organisation in testing, certification and inspection. Temperatures during failure approximately 300°C lower than comparable Li-ion cells shown in Accelerated Rate Calorimetry testing carried out as part the Industrial Sprint, by the University of Oxford. Improved capacity at higher discharge rates. o D5 prototypes can be discharged at twice the rate of P1 prototypes without impacting their capacity. Improved safety performance of Goliath batteries relative to conventional lithium ion means that EV designers can reduce the mechanical protection and reinforcement that would otherwise be required to protect the battery pack. In turn, this enables lighter and less expensive EV designs that have a longer range for the same amount of energy. The D5 data point makes this improved safety performance clear.

Ilika plc Announces Goliath Safety Test Results Ilika plc announced that safety tests undertaken by independent expert assessors have demonstrated the superior safety of Goliath solid state cell battery prototypes relative to lithium-ion equivalent batteries. University College London carried out the nail penetration test, a standard battery safety assessment, on Ilika's Goliath P1 prototype cells. This destructive test creates an internal electrical short-circuit inside a cell by piercing the cell with a metal nail. The test simulates a catastrophic incident that would typically cause energy-dense lithium-ion cells with lithium nickel manganese cobalt oxide ("NMC") cathode chemistry (, to dangerously swell, rupture, explode, and catch fire in a process known as thermal runaway, often leading to temperatures above 600°C. Goliath P1 cells also use high-energy NMC cathode chemistry, however in the nail penetration tests the P1 cells neither exploded nor caught fire, with external temperatures remaining below 80°C. With electric vehicles ("EVs") expected to play a key role in the NetZero transition, solid state batteries are anticipated to provide a safer battery solution for next-generation EVs. It is expected that a combination of improved safety performance and high energy density will reduce the complexity of battery packs. The reduction of parasitic packaging is, in turn, expected to lead to lighter and safer vehicles with longer driving range. Testing was carried out as part of a short collaborative study, in association with the Faraday Institution SafeBatt project,which aims to develop an improved understanding of safety in next generation battery technologies. The study involves Ilika alongside researchers from the University of Oxford and University College London. The core Safebatt project explores the science of battery safety and works closely with UK battery developers and manufacturers like Ilika to inform industrial design and deployment.
