There was an article in my newspaper today regarding the new GM "Ultium Battery Technology". Here are three quotes from the article written by Peter Douglas:
"Pioneered in conjunction with LG Chem, Ultiums will compete with the incredible batteries made by Tesla. They are fashioned from interlocking cells that are encased in a polymer instead of metal, and they use 70% less cobalt, a problematic metal. GM will mass-produce them at a new plant in Lordstown, Ohio. They hope to drive battery costs below $100 per KWh, reducing the price of their EVs considerably."
"The Ultium battery cells can be stacked vertically or horizontally to produce lighter batteries in an endless variety of sizes and shapes. The flexibility will allow GM to customize battery configurations for a wide variety of vehicles. Battery capacities will theoretically range from 50 to a whopping 200 KWh. GM claims that their largest arrays will deliver 400 miles on a single charge."
"Most Ultium vehicles will run on 400 volts and accept rapid supercharging at 200 KW. GM's electric trucks will crank the voltage up to 800 and supercharge at a blazing 350 KW!"
