Europe is reaching a critical stage in solid-state battery development, creating a clearer strategic backdrop for Ilika as the region looks for ways to reduce its dependence on Asian battery technology.
The collapse of Northvolt in 2025 highlighted the difficulty Europe faces in building competitive battery manufacturing capacity. Asian groups remain dominant across much of the supply chain, while several European gigafactory projects rely on Asian technology, ownership or joint-venture structures.
That leaves European automakers with a challenge. Scaling current battery technology may help close the manufacturing gap, but it does little to create meaningful differentiation. Solid-state batteries could provide an alternative route.
Ilika is developing solid-state battery technology at a time when European manufacturers are assessing how next-generation batteries could improve energy density, charging capability and supply-chain flexibility.
Solid-state batteries can use lithium metal or silicon anodes instead of conventional graphite. This matters because graphite supply is heavily concentrated in Asia. Reducing reliance on graphite could therefore improve supply-chain resilience while opening the door to higher energy density.
The technology also supports a wider range of cathode materials, including high-nickel and high-manganese chemistries. This gives manufacturers more flexibility than relying heavily on lithium iron phosphate batteries, an area where Chinese producers have already built substantial scale and expertise.
Europe needs a stronger domestic battery technology base, and solid-state development offers one potential way to build that position without simply replicating existing Asian manufacturing models.
European gigafactories first need to prove that they can operate profitably. Once that happens, later phases of factory development could begin incorporating solid-state products. That means commercial adoption will depend not only on battery performance but also on factory economics, capital investment and the pace of automotive qualification.
Ilika is positioned in a technology area that could become more important as European carmakers rethink battery strategy, but large-scale adoption remains tied to manufacturing readiness.
The potential attraction of solid-state technology is clear. Higher energy density could support longer driving ranges or smaller battery packs. Faster charging could improve vehicle usability. Greater flexibility around battery materials could also reduce exposure to concentrated supply chains.
Those factors help explain why solid-state development is becoming strategically important for Europe.
