Who makes batteries for Chevy?
Chevrolet’s electric-vehicle batteries are primarily manufactured by LG Energy Solution through General Motors’ Ultium Cells joint venture.
General Motors and LG Energy Solution formed Ultium Cells LLC to produce the nickel-rich Ultium battery cells used across Chevrolet’s EV lineup. This partnership is central to GM’s strategy to standardize its battery technology, secure domestic manufacturing, and accelerate the rollout of Chevy electric vehicles such as the Blazer EV, Equinox EV, and Silverado EV, while evolving from the earlier Bolt’s LG-supplied cells.
How the Ultium system powers Chevy's lineup
The following overview explains the main battery supplier, the technology, and its role in Chevrolet's electric-vehicle lineup.
- Ultium Cells LLC is a joint venture between General Motors and LG Energy Solution that produces GM’s Ultium battery cells in the United States.
- LG Energy Solution supplies the cell chemistry and modules that GM assembles into complete battery packs for Chevrolet EVs.
- Chevrolet models using Ultium-based architecture include the Blazer EV, Equinox EV, and Silverado EV, with earlier Bolt models having used LG cells in their packs.
- The Ultium platform uses a nickel-rich NCMA chemistry with a focus on low cobalt and flexible cell formats to support multiple vehicle sizes and ranges.
In practice, the partnership enables GM to scale North American battery production and align its EV rollout with a domestic supply chain, while LG Energy Solution benefits from a strong, vehicle-specific platform for Chevrolet models.
What this means for Chevy customers
For consumers, the arrangement translates into more US-built EV options, potential effects on price and range, and ongoing investments in charging infrastructure and software to optimize battery performance and longevity.
In summary, Chevrolet’s battery supply is led by LG Energy Solution through the Ultium Cells joint venture with GM, forming the backbone of the company’s current and upcoming electric vehicles.
Summary
Chevy relies on LG Energy Solution’s battery cells via the Ultium Cells LLC partnership with General Motors, underpinning the automaker’s Ultium-based EV lineup and future electric trucks while GM continues to pursue diversification and domestic manufacturing resilience.
