China's intellectual property authority has invalidated a key LG Chem patent related to cathode technology, intensifying the ...

Synergistic Effects of Surface Coating and Bulk Doping for High-Energy Lithium Ion Batteries For high-energy lithium ion batteries, nickel-rich layered oxides such as lithium nickel cobalt manganese ...

the highly degraded S-NCM can restore the layered structure, and the surface oxygen vacancies and O-TM content can be reduced significantly,” adds Chen. “Additionally, the upcycled cathode ...

These help to break up the spent cathode material from the batteries—lithium-coated nickel cobalt manganese oxide (NCM). The NCM particles are mixed with an iron(II) salt, sodium oxalate ...
