Summary: Ga2O3 is widely used as anode material for lithium-ion batteries due to its high theoretical capacity. However, it has limited electronic conductivity and severe volume expansion, which restrict its application. In this study, Ga2O3 nanospheres were coated with carbon to improve overall electrochemical performance. The carbon coating treatment not only shortened ion transmission path and improved cycle stability but also provided abundant lithium-ion storage space, resulting in high pseudocapacitive storage characteristics.

Summary: This study proposes a solvent-free Zn-In alloying powder electrode as a replacement for Zn foil in aqueous Zn-ion batteries. The electrode manufacturing process involves no solvent and forms a 3D Zn deposition network with carbon, providing a uniform electric field distribution. The addition of In on the surface of Zn powder improves the morphology of Zn deposition and suppresses Zn dendrite growth. The solvent-free Zn electrodes enable high cathode loading and stable cycling in Zn-MnO2 batteries, with no gas evolution at high areal capacity.

Summary: Despite the development of various anode materials, graphite remains dominant due to its excellent cyclic performance. However, there is a need to boost the energy and power capacities of lithium-ion batteries (LIBs) for electric and hybrid cars. Carbon nanostructures have been anticipated as a solution, but their widespread use is still in its infancy due to low densities. This review focuses on recent developments in creating LIBs with enhanced capacity, rate performance, and cyclic stability using carbon nanostructure-based anodes.
