From an article published 3 years ago in Resource World Magazine:

"GENERAL MOTORS

GM produces two notable electric vehicles, the Chevy BOLT EV, a BEV, and the Chevy VOLT an electric/ICE hybrid. The VOLT uses a blend of LMO and lithium-nickel-manganese-cobalt oxide (NMC) in its battery packs while the BOLT uses just NMC. Like Nissan’s Leaf, the Chevy battery packs get their power from groupings of large format pouch cells packs, but with the added feature of built in battery pack cooling.

As a consequence, the batteries in the GM vehicles have better longevity. GM’s batteries are made by an external supplier, LG Chem of Korea. GM’s electric vehicles are world class in engineering, but take a back seat to GM’s ICE vehicles in marketing. GM only expects to sell about 30,000 BOLTs each year in contrast to 500,000 Teslas. In my opinion, GM wants a horse in the electric vehicle race, but thinks ICE vehicles will continue to be preferred by consumers for the near term future, so it does not aggressively market its electrics."
