In 2021, LG Energy Solution will begin manufacturing batteries with nickel, cobalt, manganese, and aluminum (NCMA) anode materials, and will supply them to Tesla, industry sources said.
LG's new battery business is set to become the first company to make NCMA batteries for electric vehicles. LG Energy Solution said it will manufacture batteries, 90 percent of which will be nickel, starting in the second half of 2021.
An official representative of LG Energy Solution said that he could not confirm that the company will supply batteries to Tesla because they cannot divulge the names of their customers. However, the company is ramping up production capacity at its plant in Nanjing, China, which makes cylindrical battery cells used in Tesla vehicles. The company is reported to be supplying NCMA batteries for Tesla Model Y.
The cathode of an NCMA battery is 90 percent nickel, and the cobalt percentage is less than 5 percent. The high percentage of nickel increases energy density and allows electric vehicles to travel up to 373 miles (600 kilometers) on a single charge. Existing batteries only allowed vehicles to travel 310 miles (500 kilometers) on a single charge.
LG Energy Solution has lowered the cost of batteries by cutting down on cobalt use and replacing it with aluminum. Aluminum is known to counterbalance instability that can occur in a cathode with a high energy density.
