Volkswagen Group’s push to control more of its electric future has taken a tangible step forward. PowerCo, the battery company created within the Group, has officially put its Salzgitter gigafactory into operation, producing the first unified battery cells proudly labeled “Made in Europe.” For an industry still heavily dependent on Asian supply chains, this is more than a symbolic milestone—it’s a strategic statement.
PowerCo’s approach is clear and ambitious: design, develop, and manufacture battery cells entirely in Europe. By doing so, Volkswagen aims to strengthen technological sovereignty while reducing exposure to geopolitical and supply-chain risks that have become painfully visible over the last few years. The first cells rolling out of Salzgitter are now headed to Volkswagen Group brands for final road testing, with their market debut scheduled for next year in electric models from Volkswagen, Škoda, and Seat/Cupra.
At the heart of this strategy is standardization. PowerCo’s “unified cell” concept is designed to work across multiple brands, platforms, and global regions. Within the Group, PowerCo is expected to cover around 50 percent of demand for these standardized cells, with the remainder sourced from external suppliers. The payoff is scale: a single cell architecture that can be produced in large volumes, adapted to different chemistries, and deployed worldwide.
That flexibility is one of the unified cell’s strongest cards. The architecture supports multiple battery chemistries, ranging from cost-focused lithium iron phosphate (LFP) to higher-performance nickel manganese cobalt (NMC), and eventually solid-state technology. This allows Volkswagen to tailor batteries to different vehicle segments and markets without reinventing the wheel each time.
The first production-ready unified cell is based on NMC chemistry and targets the mass market—without sacrificing performance. Compared to previous generations, it delivers around 10 percent higher energy density, a meaningful gain in an era where every kilometer of range counts. Crucially, the cell has been developed in parallel with Volkswagen’s new “cell-to-block” battery system. This tighter integration improves packaging efficiency, reduces weight, and translates into tangible benefits in range, efficiency, and overall performance.
Salzgitter isn’t just another factory; it’s the blueprint. Initial capacity is set at up to 20 GWh annually, enough to supply batteries for approximately 250,000 electric vehicles. If demand requires it, the site can be expanded to 40 GWh. More importantly, Salzgitter will serve as the lead plant for future PowerCo gigafactories, including planned sites in Valencia, Spain, and St. Thomas, Canada.
From an automotive perspective, this move signals a shift in how legacy manufacturers approach electrification. Instead of relying almost entirely on suppliers, Volkswagen is vertically integrating one of the most critical components of an EV. Batteries are no longer just parts; they define cost structures, vehicle architecture, and brand competitiveness.
For customers, the implications should be equally significant. Standardized cells promise more predictable pricing, faster development cycles, and quicker rollout of new technologies across multiple models. The arrival of LFP-based unified cells in the future could also open the door to more affordable electric vehicles, while solid-state development keeps the long-term performance race alive.
PowerCo’s Salzgitter launch won’t grab headlines like a new sports car or concept vehicle, but its importance may ultimately outweigh both. In the electric era, batteries are the new engines—and Volkswagen has just started building its own at scale, right in the heart of Europe.
