Cobalt-free batteries, which are more ethical and potentially safer, are now dominant in Chinese electric vehicles, but the US has yet to adopt this technology widely, highlighting a shift in battery manufacturing and sourcing strategies.
Scientists at the University of California, Irvine have developed a new way to use nickel in lithium-ion batteries, reducing or eliminating the need for cobalt, which is often mined using child labor. The team spent three years devising a process called "complex concentrated doping" that enables the scientists to alter the key chemical formula in lithium-ion batteries. The doping process eliminates the need for cobalt in commercial components critical for lithium-ion battery functioning and replaces it with nickel, making it a more attractive alternative to cobalt-based batteries.
