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.

Here we adopted a hybrid technique coupled with template-directed heteroepitaxial growth method to fabricate single-crystal-like, nanotwinned (nt) Ni. The nt Ni primarily contains hierarchical twin structures that consist of coherent and incoherent twin boundary segments with few conventional grain boundaries. —Li et al.

Bar chart showing the specific activities of Pt/C, Pt poly-crystal electrode, IL-encapsulated Pt 3 Ni nanoframes/C, PtNi-Meso-TF, and Pt 3 Ni(111)-Skin electrode, and the corresponding improvement factors vs. Pt/C. Annealing these dodecahedron nanoframes in argon gas creates a platinum skin on the nanoframe surfaces.

Water splitting with electricity—electrolysis—is a simple and old idea: a power source connects to two electrodes placed in water. The nickel foam acts as a conductor—transporting electricity from the power source—and the nickel-iron hydroxide sparks the electrolysis, separating water into oxygen and hydrogen.

As an example, the military’s BB-2590 Li-ion battery used in a range of portable systems calls for a cycle life of ≥224 and ≥ 3 years.). LIB capacity is limited in part by the intercalation of Li ions by the anode material—i.e., Envia is targeting its high energy density Li-ion cells at plug-in hybrid and electric vehicles.
