TOKYO — Tesla's battery cell supplier Panasonic said on Wednesday it is aiming to develop automotive batteries without using cobalt in the near future, amid soaring prices of the key battery ingredient.
Top battery makers are scrambling to reduce cobalt content in lithium-ion batteries as prices of the mineral have multiplied over the recent years and the spread of electric vehicles is expected to result in cobalt shortages eventually.
"We have already cut down cobalt usage substantially," Kenji Tamura, who is in charge of Panasonic's automotive battery business, said at a meeting with analysts.
"We are aiming to achieve zero usage in the near future, and development is underway. . . ."
