SMM5, March 22: recently, it has been reported that General Motors will start construction of a battery plant at LG Chemical in Loddstown, Ohio, USA. The plant, with an investment of US $2.3 billion, will use batteries from the 2022 GMC HUMMER EV electric full-size pickup to the new Chevrolet Bolt.
It is reported that the new factory, named Ultium Cells LLC, covers an area of about 30 football fields and will be able to provide 1100 new jobs a month when it is officially completed. It is expected to start production in 2022, and the planned annual production capacity is 30GWh.After 2023, the production capacity will reach its peak.
General Motors and LG Chemical also signed a joint research and development agreement to jointly promote the development and application of advanced battery technology and further reduce battery costs, which is the power battery Ultium jointly developed by the two sides.
Ultium is an NCMA quaternary lithium battery that reduces the amount of cobalt in the battery by about 70 per cent by adding aluminum. GM demonstrated the battery at Electric EV Night in March. Battery capacity ranges from 50kWh to 200kWh, and battery costs will be reduced to $100 per kWh,. Mileage is expected to reach nearly 644km. It is worth mentioning that because cobalt metal is very expensive, this will effectively reduce the production cost of power batteries.
