The South Korean manufacturer SK Innovation has begun construction on a new battery cell factory in the Chinese province of Jiangsu. The Changzhou factory is planned to have an annual capacity of 7.5 GWh.
Together with another currently-under-construction 7.5 GWh battery cell factory in Hungary and the production capacity boost in Seosan to 4.7 GWh, the manufacturer plans to reach an annual capacity of 20 GWh.
Next to SK Innovation, South Korean rivals LG Chem and Samsung SDI are also producing battery cells in China. The three companies are not limiting themselves to the production of battery cells, however, and are planning to develop batteries with less cobalt dependency in the next 3 to 4 years, as well as diversifying their resource suppliers. The manufacturers aim to change the current 6:2:2 nickel, cobalt and manganese ratio to a 8:1:1 relation, specifically.
