French company VoltR has raised €22 million, combining €16 million in equity and €6 million in grants, to expand battery remanufacturing. It plans to double its Verrières-en-Anjou factory footprint, increase production capacity sixfold within two years and add about 40 jobs.

French battery remanufacturer VoltR has raised €22 million to expand its factory in Verrières-en-Anjou and increase production capacity sixfold within two years, the company said. The financing is intended to scale its process for reusing suitable cells from used lithium batteries and support its expansion in Europe.

The financing includes €16 million in equity from the SPI 2 fund, managed by Bpifrance on behalf of the French state under the France 2030 program, and Decathlon Pulse, the sporting goods retailer’s investment and innovation arm. A further €6 million comes from grants awarded under the Première Usine program.

VoltR said it will use the funds to double the footprint of its Verrières-en-Anjou factory in western France. It also plans to double its workforce and create about 40 jobs as production scales. The company has not provided a detailed construction schedule or a breakdown of how the funding will be divided among the expansion, equipment and hiring.

VoltR collects used lithium batteries, assesses their individual cells and uses cells it considers suitable to make new battery systems. The company said it has put more than 20,000 remanufactured batteries on the market over the past four years. It lists several potential applications for its products, including energy storage systems, but the financing announcement did not specify customer orders or volumes by application.

The developmentVoltR announced €22 million in financing to scale its battery remanufacturing operations and expand production in France.

Scaling Reuse Beyond the Factory

The planned expansion would increase the scale at which VoltR can process and reuse cells that have reached the end of their first use. Remanufacturing can keep suitable battery cells in service for other applications, rather than directing every used battery immediately toward material recovery or disposal. The company says its approach is intended to extend the industrial life of existing cells.

VoltR also frames the project as a contribution to Europe’s battery value chain, with the aim of reducing demand for newly sourced raw materials. That is a company goal, not a reported measurement of material savings: the announcement gives no forecast for tonnes of raw materials avoided, emissions reduced or the share of cells that can be reused. The planned sixfold capacity increase would expand the operation, but its effect on European supply will depend on production, sourcing and customer demand.

The funding brings together public support and private investment. Bpifrance is managing the SPI 2 fund on behalf of the French state, while Decathlon Pulse is participating as an investor. VoltR said the investors bring industrialization expertise and knowledge of battery applications and markets. Their participation provides funding for the expansion, but the announcement does not describe an exclusive supply or purchasing agreement with Decathlon.

How VoltR Remanufactures Cells

Battery remanufacturing differs from making battery systems entirely from new cells. VoltR’s stated process begins with collecting used batteries, then assessing cells individually and selecting suitable ones for new systems. Cells that are not selected do not become remanufactured products through this process; the company’s announcement does not explain their subsequent treatment.

The company says it has marketed more than 20,000 remanufactured batteries during the past four years. That figure provides a record of prior sales or market placements as reported by VoltR, but it does not state how many batteries the firm currently produces annually, how much capacity it has today or what unit of capacity its sixfold target uses.

The funding’s French public component is tied to the France 2030 program: €16 million in equity is coming through SPI 2, and €6 million in grants was awarded under Première Usine. VoltR says the new investment will help establish remanufacturing within Europe’s battery industry. Its plans for European expansion are not accompanied by named new sites, countries or dates in the report.

Production Targets Still Need Detail

The announcement does not state VoltR’s current annual production capacity, the baseline against which the sixfold increase will be measured, or the specific output expected after two years. It also gives no timetable for construction or equipment installation, so the pace of the factory expansion is not yet clear.

Other details remain unreported, including the types and quantities of batteries VoltR expects to source, the proportion of collected cells that pass its assessment, and which products or customers will account for increased output. The company’s stated aim to reduce demand for new raw materials is not accompanied by an estimate of the savings or an independent impact assessment.

The report identifies energy storage systems as one possible application, but does not confirm a new product launch, customer contract or European site outside France. The company’s planned hiring of about 40 people is also a target; the announcement does not provide a recruitment schedule.

Factory Expansion Over Two Years

The next stated milestones are the planned factory-footprint expansion in Verrières-en-Anjou and the effort to reach six times current production capacity within two years. VoltR also plans to double its workforce, with about 40 jobs expected as it scales. The company has not announced specific dates for construction phases or when additional production lines will begin operating.

Further updates will be needed to establish whether the company meets those targets and how the added capacity is used. Relevant details would include annual output, customer and application mix, cell sourcing and how many collected cells can be remanufactured. VoltR has not named a schedule for announcing those figures or for any expansion beyond its French factory.
