Rechargeable zinc-ion batteries (RZIBs) utilizing aqueous electrolytes can offer high safety, low cost, and fast charge/discharge ratings for large-scale energy storage. The use of water as electrolyte solvent facilitates facile processing, reduced safety concerns, ion kinetics. However, free molecules also instigate many simultaneously occurring undesired reactions in the RZIB system, leading to capacity fade limited operational lifetime. Here, our review traces each reaction its cascade...

Rechargeable zinc-ion batteries (RZIB) present an interesting alternative to rechargeable Li-ion batteries. Among the active materials, layered vanadium-based oxides show a poor cell voltage but modifying this structure by attaching phosphate group vanadium redox center can drastically enhance cathode voltage.

Aqueous rechargeable zinc-ion batteries are emerging as attractive alternatives for post-lithium-ion batteries. However, their electrochemical performances restricted by the narrow working window of materials in aqueous electrolytes. Herein, a Ni-mediated VO2-B nanobelt [(Ni)VO2] has been designed to optimize intrinsic electronic structure and thus achieve much more enhanced storage. Specifically, Zn/(Ni)VO2 battery yields good rate capability (182.0 mA h g-1 at 5 A g-1) with superior...

Rechargeable zinc-ion batteries (RZIBs) are mostly powered by aqueous electrolytes. However, uncontrolled water interactions often confer a small voltage window and poor battery capacity retention. Here, we explore replacing with ethylene glycol as the primary solvent in zinc electrolyte formulations.

Highly reversible Mg battery chemistry demands a suitable electrolyte formulation highly compatible with currently available electrodes. In general, conventional electrolytes form passivation layer on the anode, requiring use of MgCl2 additives that lead to severe corrosion cell components and low anodic stability.
