Projet R&D HYDRA

Hybrid power-energy electrodes for next generation lithium-ion batteries

Personal electronic devices, electric vehicles… The lithium-ion (Li-ion) battery is a technology already used in a wide range of products. In addition to these uses, it also represents a key technology for a number of emerging markets, such as the integration of renewable energies into the national electricity grid and for the aerospace industry.

To ensure the development of these markets, new technological innovations in Li-ion batteries are required. Technological changes are needed to improve performance and reduce dependence on critical raw materials.
The Hydra project, funded by the European Union, aims to develop a new generation of Li-ion battery technology using sustainable materials, with improved capacity and energy output, while keeping production costs under control. It will result in a pilot-scale cell production line capable of producing high-energy, long-life batteries. In addition, through the investments made by the project’s industrial partners, Hydra will encourage the strategic battery market to take root in Europe.



The Future Battery Industries Cooperative Research Centre fosters the growth of the battery industries to power Australia’s future. We bring together industry, researchers, government and the community to ensure Australia plays a leading role in the global battery revolution.

Electrode for ionic-liquid batteries

méthode de préparation d'une électrode pour batterie à base de liquide ionique

Method for preparing an electrode with high load per unit of mass filled with electrolyte for a battery with high energy density

The present invention relates to a method for preparing batteries with high energy density. more particularly, it relates to an improved method for preparing an electrode with high load per unit of mass for a metal-ion battery with high energy density. This method involves preparing an electrolyte-filled solid electrode by mixing a salt, a solvent, a binder and an active material in order to produce a mechanically stable paste.



AXELERA is the Chemistry-Environment competitiveness cluster based in Auvergne-Rhône-Alpes. It brings together, in France and internationally, the players involved in the controlled management of matter and resources (water, air, soil, energy) for the sustainable development of territories.

The AXELERA cluster was created in 2005 by 6 founding members: ARKEMA, CNRS, ENGIE, IFP Energies nouvelles, SOLVAY and SUEZ. These players are heavily involved in the cluster’s governance, alongside start-ups, an ETI, a higher education college and MICHELIN as a premium member. The cluster is supported by 6 funding partners: the Auvergne-Rhône-Alpes Region, the Metropole of Lyon, Grenoble-Alpes Métropole, Clermont-Auvergne Métropole, the French State (DGE) and the European Union. Solvionic is one of the partner companies, contributing to the cluster through projects such as EPSILON.

Process for manufacturing and use of a gel polymer electrolyte

Illustration processus de fabrication d’un électrolyte polymère gélifié

The invention relates to a process for manufacturing a gelled polymer electrolyte (GPE), comprising the steps of:

  1. solubilizing a polymer in a solvent, leading to the formation of a first homogeneous solution;
  2. mixing said solution with an electrolyte consisting of aluminum chloride with a predetermined weight ratio of electrolyte to polymer;
  3. mixing said mixture until a second homogeneous solution is obtained;- pouring said second homogeneous solution onto a substrate;
  4. removing/evaporating the solvent to obtain a homogeneous GPE membrane: polymer;- mixing said mixture until a second homogeneous solution is obtained;
  5. pouring said second homogeneous solution onto a substrate;
  6. removing/evaporating the solvent to obtain a homogeneous, mechanically stable GPE membrane;
  7. activating the polymer membrane, to further etch/deposit aluminum on the GPE membrane.
