China is well advanced in switching to the NCM 811 type of lithium-ion cathode for EV batteries.
The new NCM 811 lithium-ion battery chemistry takes the Chinese passenger xEV (BEV, PHEV, HEV) market like a storm.
According to Adamas Intelligence, In September, NCM 811 was responsible for 18% of passenger xEV battery deployment (by capacity).
The NCM 811 is a low cobalt-content cathode (nickel:cobalt:manganese at a ratio of 8:1:1).
The expansion is tremendous compared to 1% in January, 4% in June and 13% in August.
NCM 811 cells combines high-energy density with affordability (lower content of expensive cobalt), which probably is enough for most manufacturers to make the switch from NCM 523 and LFP (often bypassing NCM 622).
"In China, for the second month in a row, NCM 811 was second-only to NCM 523 by capacity deployed, while the once-popular NCM 622 now finds itself in fifth spot with a mere 5% of the market.
In the pursuit of lower costs and higher energy density, a growing number of automakers in China have seemingly opted to bypass NCM 622, shifting instead straight from LFP or NCM 523 cathode chemistries into high-nickel NCM 811.
Since January 2019, the market share of NCM 811 in China’s passenger EV market has rapidly increased from less than 1% to 18% and shows little signs of slowing its ingress. Outside of China, however, automakers have been slow to adopt NCM 811 to-date but we expect to see the chemistry make inroads in Europe and North America by as early as next year."
NCM 811 share globally is also growing and in September it was at 7%.
The other leading low cobalt chemistry is Tesla/Panasonic's NCA.
