SVOLT announced the start of mass production of the cobalt-free cathode material for its NMX battery cells

18 April 2021, 07:18:28

SVOLT announced the start of mass production of the cobalt-free cathode material for its NMX battery cellsSVOLT announced that it has started mass production of the cobalt-free cathode material for its NMX battery cells in Jintan, in eastern China. In January 2021, the pilot production of 10 tonnes of cobalt-free cathode material was successfully completed in the battery cell factory in Jintan. In its current development stage, the cell factory now produces 5,000 tonnes of the main material for cobalt-free battery production per year.

Nickel manganese battery cells (NMX) completely dispense with the heavy metal cobalt, which is otherwise used for stabilisation of high-nickel battery cells. SVOLT is thus the only company currently on the market that has managed to bring high-nickel cell chemistry without cobalt to mass production readiness.

For cobalt-free NMX battery cells, SVOLT has developed a new cathode material that consists of 75 percent nickel and 25 percent manganese and is completely cobalt-free. The cathode is stabilised by means of specially developed doping and coating processes. NMX cells – even without cobalt – therefore achieve higher thermal stability and overall safety than NCM811 cells.

The first cobalt-free battery cells, which are more sustainable and cheaper than comparable NCM811 battery cells, will leave the production line as of June 2021. The first two SVOLT NMX cell variants have been available to order worldwide since mid-December 2020.
