Current lithium-ion batteries are comprised of cathode material, anode material, electrolytes and separators. The cathode material includes nickel, cobalt and manganese, whose proportion is currently at a 6:2:2 ratio. But the three firms are developing new batteries to change the ratio to 8:1:1.
Improving the proportion of nickel could allow EVs to run farther on a single charge.
"The new batteries with the reduced portion of cobalt could be developed in three to four years, although it would be difficult to get rid of cobalt completely anytime soon," said a source from LG Chem.
