Who makes Chevy Volt batteries?
The lithium-ion battery cells for the Chevrolet Volt are supplied by LG Chem, now LG Energy Solution, with General Motors handling the final pack assembly at its facilities in Michigan.
Cell supply and manufacture
To understand who makes the Volt’s batteries, it helps to separate the cell supplier from the pack assembly. The cells themselves come from LG Chem, a South Korean company that has produced automotive lithium-ion cells for GM and other automakers for years.
- LG Chem (South Korea), now LG Energy Solution, provides the lithium-ion battery cells used in the Volt’s packs under contract with General Motors.
In short, LG Chem supplies the essential cells, and GM integrates them into complete packs at its own manufacturing sites.
Pack assembly and production sites
The cells are manufactured by LG Chem at its facilities in Asia, with the final battery packs assembled by GM at a Michigan facility to meet GM's integration standards.
- Brownstown Township, Michigan: GM's battery-pack assembly plant for the Volt, where modules were put into the final pack.
This arrangement meant a hybrid approach: cells from LG Chem, assembled into complete packs at GM's own manufacturing sites in the United States.
Generation details
Gen 1 (2010–2015): 16 kWh pack
The first-generation Volt used a 16 kWh lithium-ion battery pack designed for plug-in hybrid operation, with an all-electric range in the mid-30s miles on the EPA cycle.
Gen 2 (2015–2019): 18.4 kWh pack
The second generation expanded to an 18.4 kWh pack, improving the all-electric range to about 53 miles on the EPA cycle, while retaining a gasoline engine for extended-range capability.
Note: The Volt was discontinued after the 2019 model year, as GM shifted its focus to the broader Chevrolet electric-vehicle lineup. LG Energy Solution remains a major supplier for GM’s newer EV programs.
Summary
In brief, the Chevy Volt’s batteries are made from cells supplied by LG Chem (now LG Energy Solution), with the final packs assembled by General Motors at its Michigan facilities. The Gen 1 and Gen 2 Volt used 16 kWh and 18.4 kWh packs, respectively, before the model was retired in favor of GM’s newer electric-vehicle lineup.
Where are Chevy Volt batteries made?

Who supplies the batteries for the Chevy EV?
CATL
The automaker will source low-cost LFP batteries from CATL for about two years to support its next-gen Chevrolet Bolt production. The new model will be GM's most affordable EV, which can be expected to start around $30,000 and hit dealerships in 2026.
