The Race for Longer Battery Life
July 24, 2020—Researchers have developed a new type of battery that could allow for longer use in electric vehicles. The battery has the potential to increase travel distances by hundreds of miles for cars and planes.
According to Science Daily, the researchers are replacing the graphite anodes that are currently used in EVs, with lithium metal anodes. Lithium metal extends an EV's driving range by 30 to 50 percent, but it comes at a cost.
Lithium dendrites are tiny, treelike defects that appear on the anode after many charges, and can shorten the battery's life. Researchers at the Berkeley Lab are collaborating with Carnegie Mellon University to develop a third material to suppress the dendrites.
