Electrolyte storage

With its materials chemistry expertise, EQUANS France manages the electrolyte distribution and storage chain. A process that calls for real expertise given the extreme instability of this solvent on contact with air.

EQUANS masters the distribution process from start to finish

The success of electric vehicles is massively dependent on their batteries. These batteries are composed of an anode, a cathode and… an electrolyte. Its role? To ensure conductivity of the lithium-ion between the anode and the cathode to create an electrolysis reaction. A step that is one of the most difficult because of the highly explosive and flammable potential of the electrolyte. Highly unstable and hazardous, this solvent calls for full mastery of its distribution and must be stored in controlled atmosphere (ATEX) buildings.

From the drum storage cabinet to management of distribution (through PLCs) to production equipment... EQUANS France coordinates the distribution process from end to end, which calls for extraordinary expertise. To ensure effective sealing of the circuit, the electrolyte circulates in stainless steel, double wall pipes, with circulation of nitrogen in the double envelope to detect leaks. A configuration that protects not only the equipment but also the user, because the electrolyte must never come into contact with the air at the risk of exploding.

Spotlight on electrolyte storage

Working alongside manufacturers, the EQUANS France teams advise their clients in the choice of materials to guarantee the perfect “containment” and storage of the electrolyte. EQUANS France offers tailored solutions that meet the needs, challenges and requirements of every client.
