High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

This is due to the lack of electrocatalysts that successfully reduce and generate oxygen during the discharging and charging of a battery. Other two amorphous bimetallic, Ni 0.4 O x and Ni 0.33 In contrast, our method produces a family of new high-performance and low-cost catalysts. —Professor Yuan Chen.
