GM offers clues to technology aimed at slashing EV battery costs

General Motors Co is testing a variety of battery chemistries, technologies and manufacturing processes aimed at slashing the cost of future electric vehicle batteries and reducing its dependence on such price-sensitive metals as cobalt, President Mark Reuss said on Wednesday. Reuss, speaking at an investor conference, said GM is experimenting with silicon-rich and lithium metal anodes, solid state and high voltage electrolytes, and dry processing of electrodes for its next generation of Ultium batteries, due around 2025. The competition to fine-tune proprietary technology to cut electric vehicle battery costs is replacing horsepower wars as the battleground for deciding the industry’s winners and losers.
