A new collaboration between a Taiwanese battery maker and a French research agency is designing electric vehicle battery packs with one goal in mind: make them simple to take apart. The result could change how batteries are repaired, recycled, and remanufactured, while giving Europe more control over its battery supply chain.

Taiwan and France team up on removable, serviceable battery packs

ProLogium, a battery company based in Taipei, has joined forces with CEA, France’s Alternative Energies and Atomic Energy Commission. Together they are developing a modular pack built around a clear plan for disassembly.

The partners say the architecture lets technicians remove modules from the pack and access cells without cutting, crushing, or destroying components. That design choice aims to make end-of-life work simpler and less risky.

What “design-for-disassembly” actually means for batteries

The concept flips standard manufacturing logic. Instead of gluing and welding cells into hard-to-service enclosures, the pack is assembled so parts can be separated again.

• Modular units slide or unbolt from the main pack.
• Modules are arranged for fast access to cells and sensors.
• Fasteners and connectors are chosen to avoid destructive removal.

Technical backbone: solid-state chemistry and a rigid electrolyte

The project centers on a solid-state design that uses a firm electrolyte. That contrasts with typical lithium-ion packs, which rely on a liquid electrolyte that can catch fire under some conditions.

Solid-state cells route ions through a solid medium. The chemistry reduces flammability and can improve energy density, cycle life, and charging speed.

Real advantages: repairs, recycling, reuse

The immediate wins are practical. Easier repairs, recycling, and reuse become feasible when parts are recoverable in good condition.

• Repair shops can replace only damaged modules instead of entire packs.
• Cells that still hold capacity can be repurposed for second-life applications.
• Recyclers receive cleaner streams of materials, cutting processing costs.

Those improvements reduce the need to extract fresh raw materials. Mining for battery metals is expensive and environmentally damaging. Extending component life helps lower demand for newly mined resources.

How this supports regional industry and a circular economy

ProLogium and CEA argue the design offers more than technical gains. It helps build a localized, resilient battery ecosystem in Europe.

• Industrial autonomy: easier maintenance and recycling keep value within regions.
• Scalability: standardized modules make it easier to deploy local repair and recycling capacity.
• Circular economy: recovered materials flow back into manufacturing, shrinking waste.

By reducing dependence on long supply chains, the approach can strengthen national and regional strategies for energy transition.

Where solid-state batteries shine — and where they still stumble

Solid-state cells promise safety and performance benefits over liquid-electrolyte lithium-ion packs. They are generally lighter, less prone to thermal runaway, and can support higher charging rates.

Yet cost-effective mass production remains a hurdle. Manufacturers are racing to close that gap. Several automakers and startups have reported progress, but scaling to car-level volumes is still a major engineering and industrial challenge.

Environmental and consumer impacts: lower emissions, lower costs

Making batteries more serviceable can feed directly into lower lifecycle emissions. Reusing and recycling parts reduces the extraction and processing footprint tied to new batteries.

For drivers, that can translate to cheaper electric vehicles over time. If pack costs fall and recycling supplies recycled materials back into production, vehicle prices could drop.

• Each EV removes thousands of pounds of tailpipe greenhouse gases compared with a gasoline car.
• Owners often save on fuel and maintenance, sometimes more than $1,000 per year.
• Government incentives and tax credits can further lower purchase costs.

Companies that help pair EV purchases with home solar systems argue that solar charging can further reduce operating costs and emissions.

Prototype stage and the path to production

ProLogium says it has built a prototype demonstrating the modular, removable pack. CEA has contributed engineering know-how for testing and validation.

The partners position the project as a lever for strategic objectives: carbon neutrality, industrial resilience, and circular practices. They aim to prove that disassembly-friendly packs can be manufactured and serviced at scale.

Next steps include refining manufacturing methods, validating long-term durability, and integrating the design into vehicle platforms. If successful, the approach could accelerate the shift to safer, more sustainable battery systems.
