(Reuters) – Common Motors Co is testing quite a lot of battery chemistries, applied sciences and manufacturing processes aimed toward slashing the price of future electrical automobile batteries and decreasing its dependence on such price-sensitive metals as cobalt, President Mark Reuss mentioned on Wednesday.
Reuss, talking at an investor convention, mentioned GM is experimenting with silicon-rich and lithium metallic anodes, stable state and excessive voltage electrolytes, and dry processing of electrodes for its subsequent era of Ultium batteries, due round 2025.
The competitors to fine-tune proprietary know-how to chop electrical automobile battery prices is changing horsepower wars because the battleground for deciding the business’s winners and losers.
GM has mentioned it goals to cut back battery cell price to nicely beneath $100 per kilowatt-hour by 2025, in contrast with greater than $150/kW right now. GM executives even have mentioned the corporate expects its future EV batteries to final for 1,000,000 miles or extra, with driving ranges of 500-600 miles (805 to 965 km) between costs.
The automaker’s $2.3-billion three way partnership with Korea’s LG Vitality Resolution is because of begin producing Ultium battery cells in Lordstown, Ohio, in 2022.
That battery, which might be utilized in new GM electrical autos such because the Hummer EV and Cadillac Lyriq, makes use of graphite-based anodes, nickel-cobalt-manganese-aluminum (NCMA) cathodes and liquid electrolyte.
GM and LG are anticipated shortly to announce a second EV battery plant in Tennessee, to additional help GM’s manufacturing goal of 1 million electrical autos a yr by 2025.
Citing GM’s funding in and know-how partnership with Massachusetts-based battery startup SES, Reuss mentioned GM is “open to totally different partnerships and totally different applied sciences” in its ongoing efforts to cut back battery price and enhance power density to increase electrical automobile vary.
He mentioned “the provision chain goes to blow up” with demand for cobalt, nickel and different metals as GM and opponents ramp up EV manufacturing over the following 5 years.
Reuss mentioned the corporate is “on the lookout for breakthroughs” with the intention to “cut back dependency on a few of these metals.”
