The dual-role Ni–N/rGO catalyst offers a scalable and versatile solution to longstanding bottlenecks in Li–O 2 battery design ...

Ex situ testing indicated that repeated redox cycling accelerates catalyst dissolution, due to near-surface reduction and the higher dissolution kinetics of metals when cycling to high potentials.

In acidic media, the molybdenum disulfide/cobalt diselenide catalyst exhibits fast hydrogen evolution kinetics with onset potential of −11 mV and Tafel slope of 36 mV per decade, which is ...
