GM partners with Peak Energy to develop sodium ion battery cells for grid storage
By Eve
GM Ventures has made a strategic investment in Peak Energy to develop sodium ion battery cells for stationary energy storage, not electric vehicles. Under the partnership announced 10 June 2026, GM will develop the cells in its Michigan battery labs and retain exclusive manufacturing rights, while Peak Energy will integrate them into its battery storage systems. Peak Energy claims its passively cooled sodium ion platform can reduce energy storage costs by 20% compared with conventional lithium iron phosphate systems while delivering more than 99% uptime.
Why it matters
The partnership targets the rapidly growing stationary storage market driven by renewable energy integration, data centres and AI infrastructure, potentially creating new manufacturing and supply opportunities in the United States. For charging point operators, lower cost grid storage could improve the economics of depot charging sites and help manage electricity demand peaks.

Stellantis begins Leapmotor B10 production in Spain to sidestep EU tariffs on Chinese EVs
Leapmotor B10 electric vehicles started rolling off the Stellantis plant in Zaragoza, Spain on 16 October 2025, with a second model, the B05 compact hatchback, due in the first quarter of 2027. Stellantis holds 51% of Leapmotor International, granting it rights to manufacture and sell Leapmotor models outside China. Local assembly allows Leapmotor to avoid EU tariffs of 21% on Chinese EV imports, on top of the standard 10% duty, enabling more competitive pricing in Europe.
Why it matters
European production of Chinese EVs without new factory investment signals a route for brands to undercut tariff barriers and price aggressively, intensifying competition for charging infrastructure operators as lower cost vehicles accelerate fleet electrification and demand for public charging.
Subaru unveils in-house EV platform and powertrain, stepping away from Toyota partnership
Subaru has revealed a fully in-house electric vehicle platform, batteries, motors and control systems at a test centre north of Tokyo, marking a shift from its Toyota collaboration that produced the Solterra (sibling to the bZ4X) and a 2024 partnership targeting four electric SUVs per brand by end 2026. The prototype, disguised in an Outback body, features an all-wheel-drive system delivering 509 horsepower (380 kW) and a 0 to 100 km/h time under 4 seconds. Subaru stated the next generation will gain greater design autonomy with less Toyota involvement.
Why it matters
Automakers developing proprietary EV platforms signal potential new supply chain opportunities for charging infrastructure providers and component suppliers outside existing joint venture arrangements. Subaru's emphasis on all-wheel-drive performance may drive demand for higher power charging solutions at dealerships and fleet depots serving markets where the brand is strong.
Sodium ion batteries enter EV and home storage markets without lithium or cobalt
Sodium ion batteries are beginning to reach commercial markets for electric vehicles and home energy storage, according to a TikTok video by @thegarbagequeen. The batteries contain neither lithium nor cobalt and can be made with sodium from existing industrial byproducts. Sodium ion batteries are described as more stable than lithium and use materials that are more abundant and less detrimental to human health and the environment, with prices expected to become competitive with lithium ion batteries.
Why it matters
The emergence of sodium ion batteries offers procurement teams an alternative chemistry for EV charging infrastructure and energy storage projects, potentially reducing supply chain risks tied to lithium and cobalt sourcing. The technology's competitive pricing trajectory and lower environmental impact may influence future specifications for grid scale storage supporting charging networks.
