GM tweaks cell electrodes to boost battery output.

GM has announced that the 2020 Chevrolet Bolt EV will offer an EPA-estimated 415 km of range on a full charge (a 34 km increase over previous model years) without actually changing the battery packs.

“The Bolt EV set the benchmark for long-range, affordable electric vehicles, and we’re excited to raise the bar by offering nearly 10 percent more EPA-estimated range for the 2020 model year,” said Tim Grewe, director of Global Battery Cell Engineering and Strategy. “At Chevrolet we’re constantly listening to customer feedback and we heard the desire for more range. The team worked diligently to find ways to improve battery energy, giving customers the confidence to go more than the extra mile.”

To boost range, without changing the actual battery pack, Chevrolet engineers improved the energy of the cell electrodes by making changes to the cell chemistry.
