Nanjing researchers design new Li-rich layered cathode

Green Car Congress

Researchers at Nanjing University (China) have introduced a new layered C2/m oxide—Li 2 Ni 0.2 Compared with Li 2 MnO 3 (LMO), LNMR displays superior capacity, a more stable capacity retention rate, higher energy density and average discharge voltage. In such materials, 1/3 of the TM sites are occupied by Li phase.

New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. Boyang Li of the University of Pittsburgh is co-lead author of the paper.
