of unusual stacking sequences in other 2D nanostructures. Notably, the electronic structure of some non bulk stacked bilayers presents characteristics which are uncommon to either the bulk phase or the single monolayer, for instance, a spin-split conduction band bottom. Our main characterization technique was annular dark-field scanning transmission electron microscopy, which offers direct and reliable imaging of atomic columns. The stacking characterization approach employed here can be readily applied toward other few-layer transition metal chalcogenides and oxides.

“…Another two dimensionally structured cathode material, molybdenum disulfide, has also attracted wide attention owing to its layered structure (Figure 16e) 191. Especially, a cell comprising a graphene‐like MoS 2 cathode and ultrasmall Mg nanoparticle based anode exhibited a high initial capacity of 170 mAh g −1 and high operating voltage of 1.8 V 192. In this experiment, the larger surface area possessed by the nanosized metallic Mg compared with that of bulk Mg anodes led to the formation of a thinner and porous passivating film.…”

Secondary batteries have become important for smart grid and electric vehicle applications, and massive effort has been dedicated to optimizing the current generation and improving their energy density. Multi‐electron chemistry has paved a new path for the breaking of the barriers that exist in traditional battery research and applications, and provided new ideas for developing new battery systems that meet energy density requirements. An in‐depth understanding of multi‐electron chemistries in terms of the charge transfer mechanisms occuring during their electrochemical processes is necessary and urgent for the modification of secondary battery materials and development of secondary battery systems. In this Review, multi‐electron chemistry for high energy density electrode materials and the corresponding secondary battery systems are discussed. Specifically, four battery systems based on multi‐electron reactions are classified in this review: lithium‐ and sodium‐ion batteries based on monovalent cations; rechargeable batteries based on the insertion of polyvalent cations beyond those of alkali metals; metal–air batteries, and Li–S batteries. It is noted that challenges still exist in the development of multi‐electron chemistries that must be overcome to meet the energy density requirements of different battery systems, and much effort has more effort to be devoted to this.

“…Chen and his group investigated the performance of highly exfoliated graphene-like MoS 2 (G-MoS 2 ) composed single-and several-layer of highly exfoliated MoS 2 . 62 To enhance the kinetics of the anode, Mg nanoparticle (N-Mg) anode was also prepared. The as-prepared samples were spread into Cu (cathode) or Al (anode) foam and the electrochemical test was carried out using CR2032 coin-type cells with a THF solution of Mg(AlCl 3 Bu) 2 Chen et al carried out a fi rst-principles DFT study focusing on key issues relating to magnesium adsorption sites, theoretical capacity, and diffusion kinetics.…”

Current performance of Mg battery cathode is reviewed. Perspective for research in this fi eld is provided and discussed.Mg battery has recently gathered more and more interest as a high energy density replacement of current Li-ion battery. Signifi cant progress has been made in developing sustainable anode and novel electrolyte. However, the success of Mg battery still high demands the search of cathode material with high energy density, good rate capability, and nice cyclability. This current review focuses on the development of Mg battery cathode in the past 15 years. A detailed review about the performance and limitations of reported cathode material is provided.A perspective for this area is discussed with insights for future research direction. Three important areas that must be explored in this fi eld in near future are suggested: the investigation of high capacity cathode, the study of hybrid ion battery, and deeper understanding about the magnesiation chemistry of the cathode.
