Electric vehicle makers and battery
manufacturers are making progress in developing new lithium-ion designs, amid
persistent concerns over the supply of key materials.
Concerns over cobalt,
in particular, are forcing battery makers to move toward cobalt-light
lithium-ion formulations, said Hans Eric Melin, founder of Circular Energy
Storage, a consultancy focused on battery end-of-life management.
Foremost among these formulations is a lithium nickel-manganese-cobalt
(NMC) cathode chemistry with eight parts of nickel for each part of cobalt.
This mix, known as 811, is the latest in a line of NMC cathode chemistries
where the ratio of cobalt is being reduced in favor of other materials,
particularly nickel, which is cheaper and easier to source.
