Electric vehicles are dependent upon batteries both for power and for design. That’s why General Motors’ recent announcement was a double break-through. A $20 billion investment in electric cars comes from a new kind of battery. Traditional EV batteries are a certain shape, determining the contours of a car. But GM’s new batteries can be stacked sideways, or even around curves, because the powerhouses are “soft, flat pouches.” (Valdes-Dapena, 2020). Tesla, by contrast, uses a hard cylinder. GM’s Ultium power cells may lead to curvy designs. Another advantage: Ultium uses far less cobalt that traditional EV batteries, significant because cobalt is becoming increasingly scarce. Finally, Ultium hits the desired metric: below $100 per kilowatt hour, the price point where electric cards are competitive with gasoline engines. According to estimates, electric vehicle sales in the USA will grow to 3 million units by 2030. Next-gen batteries enable driving ranges of 400 (and soon 600) miles. Longer range electric power means more highway trips, perhaps causing a redesign of the U.S. Federal Highway System, the Canada/USA Alaska Highway or the Pan-American Highway for a regional vision that could include a sportsway, maglev or hyper loop, in addition to vehicular paths. General Motors is partnering with LG Chem. With flexible batteries, look for different shapes to come.
