Summary: Transition metals and their oxides are widely studied as anode materials for lithium-ion batteries due to their high theoretical capacities. A porous raspberry-like nickel-enhanced MnO-based carbon-containing composite (Ni/MnO-C) has been successfully synthesized, increasing the specific capacity of LIBs. The porous nanostructure provides buffer space to prevent structural damage and, when broken into smaller nanoparticles, exposes more active sites for additional capacities.

Summary: In this work, flower-like Mn-based coordination polymers constructed by nanosheets were designed and synthesized, and hierarchical structured MnO/NC composites were successfully obtained through calcination. The composites exhibited a unique yolk-shell structure composed of micro-flowers assembled from nitrogen-doped carbon nanosheets uniformly loaded with MnO nanoparticles as the outer shell and MnO/NC nanoparticle aggregates as the inner core. The composites demonstrated high specific capacity and excellent long cycle stability, attributed to the synergistic effect of the yolk-shell structure and continuous nitrogen-doped carbon coating.

Summary: The current lithium-ion batteries (LIBs) are insufficient to meet the growing demands of the battery industry, leading to extensive research on new anode materials. Ni-based anode materials have been widely explored due to their higher theoretical capacity, longer cycle life, and environmental friendliness. This review focuses on the different morphologies of NiO-based materials and their electrochemical properties. It has been found that the performance of NiO-based anodes for LIBs is influenced by factors such as morphology, crystallinity, particle size, surface area, and porosity. Carbon-supported and metal oxide doped composites of NiO structures exhibit higher specific capacities compared to pure NiO, but the issue of capacity drainages needs to be further investigated.
