How the Battery Sector Is Looking to Improve Lithium-Ion

Cobalt is mostly sourced from the politically volatile Democratic Republic of Congo.

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.
