Tech trends, promising startups

Vehicle sales in 2020 and 2021 showed widespread adoption of battery electric vehicles (BEVs). Typical BEVs currently use lithium-ion batteries, which are unstable and require expensive rare minerals, notably cobalt. Because it is crucial to refine these minerals, China controls several key chemicals even though it does not contain deposits of the ores from which these chemicals originate. Other countries, including Portugal, Sweden, Germany, France, and the USA, are seeking to localize their supply chains to resist China’s market dominance. As cobalt has been subjected to increasing criticism, many electric car enthusiasts have begun to favor lithium ferro-phosphate (LiFePO4 or LFP) batteries. Elon Musk, who founded Tesla, has promoted LFP batteries in Tesla cars.

Several startup companies are developing disruptive battery technologies. Some batteries are more stable than current offerings. Some batteries use earth-abundant minerals. Solid Power offers a battery with a solid electrolyte for superior stability. Our Next Energy has demonstrated a high-capacity battery that avoids use of nickel and cobalt.

CATL has a battery pack that combines lithium and sodium to provide reliable power in cold temperatures that would impair ordinary lithium-ion batteries. Sparkz had received subsidies for a cobalt-free lithium battery. PJPEye has a proven small-scale carbon-based battery that is adequate for ebikes but has not been scaled up for automobiles. ElecJet has a graphene-based battery but has not yet proven that it can deliver graphene products at an affordable price.

Despite the momentum of the electric car trend, the transition already has been costly and will continue to force difficult decisions on car companies. In December 2021, Stellantis CEO Carlos Tevares warned that if the transition goes too fast, vehicle quality may suffer, jobs may be lost, and corporate profits could suffer. But still, the EV trend seems unstoppable.
