SOLVIONIC

Their core work

SOLVIONIC is a French SME specializing in ionic liquids and advanced electrolyte materials, headquartered in Toulouse. They supply and develop ionic liquid-based components for next-generation batteries — including solid-state, lithium-sulphur, and lithium-ion chemistries — as well as for thermoelectric and recycling applications. Their core contribution across EU projects is providing specialized electrolyte formulations (ionogels, solid composite electrolytes, deep eutectic solvents) that enable safer, higher-performance energy storage and materials recovery.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), SOLVIONIC focused on exploratory battery chemistries — lithium-sulphur (HELIS, ALISE), aluminium-ion (ALION), and process techniques like sputtering, plasma treatment, and electrospinning. From 2019 onward, they shifted decisively toward solid-state batteries, EV-grade lithium-ion systems, and critical-raw-material-free designs (SOLiDIFY, COBRA, SeNSE, Hydra), while also branching into thermoelectrics and circular economy applications. The trend is clear: from alternative chemistry exploration to industrially relevant, EV-focused solid-state and sustainable battery technology.

SOLVIONIC is converging on solid-state electrolytes for electric vehicle batteries and expanding their ionic liquid platform into circular economy applications — expect them to be a key materials supplier for European solid-state battery scale-up efforts.

How they like to work

SOLVIONIC operates exclusively as a specialist partner, never as coordinator — consistent with their role as a materials supplier contributing deep ionic liquid expertise to larger research consortia. With 114 unique partners across 22 countries in 11 projects, they work in large, diverse consortia (averaging ~10 partners per project) and appear to be a trusted go-to supplier rather than a project leader. This makes them easy to integrate into new consortia: they know how to deliver a defined work package without needing to drive the overall agenda.

SOLVIONIC has built a wide European network spanning 114 partners in 22 countries, heavily weighted toward battery and materials research groups. Their Toulouse base places them in France's aerospace and advanced materials ecosystem, but their collaboration footprint is pan-European.

What sets them apart

SOLVIONIC occupies a rare niche: they are one of very few European SMEs that can both manufacture ionic liquids at scale and contribute as research partners in cutting-edge battery projects. Their ability to bridge materials supply and R&D makes them valuable to any consortium needing custom electrolyte formulations. With 11 H2020 battery and energy projects, they bring a track record few competing ionic liquid suppliers can match.

Highlights from their portfolio

• SeNSE
  Their largest single project (EUR 652,500), focused on silicon anode Li-ion batteries with in-cell sensors for EVs — indicates high trust from the consortium.
• SOLiDIFY
  Directly targets solid-state Li-metal battery scale-up using their core ionogel and solid composite electrolyte technology — represents the convergence of their entire expertise.
• Sol-Rec2
  Their most recent and most unexpected project — applies ionic liquid expertise to packaging recycling and circular economy, signaling diversification beyond batteries.
