Present spinel-type lithium manganese oxides have attracted much attention as positive-electrode active materials for lithium-ion rechargeable batteries, which are the most sought-after power source for various electric applications, because of their low cost, non-toxicity, and high abundance of source materials compared to the conventionally used LiCoO2 crystals. Spinel-type LiMn2O4 crystals were grown at low-temperature by using a LiCl-KCl flux. The chemical compositions, sizes, and shapes of the LiMn2O4 crystals could be tuned by simply changing the growth conditions. Among the various products, the crystals grown at a low temperature of 873 K showed a small average size of 200 nm. Electron diffraction patterns and TEM images reveal the truncated octahedral shape of the crystals. The flux growth driven by rapid cooling resulted in truncated octahedral LiMn2O4 crystals surrounded by both dominating {111} and minor {100} faces with {311} and {220} edges. Lattice images indicate that crystals grown at a lower temperature have the excellent crystallinity. The small LiMn2O4 crystals grown at 873 K showed better rate properties than the large crystals grown at 1173 K, when used as a positive active material in lithium-ion rechargeable batteries.

Alkaline zinc-based rechargeable batteries (AZRBs) are competitive candidates for future electrical energy storage because of their low-cost, eco-friendliness and high energy density. However, plagued by dendrites, the AZRBs suffer from drastic decay in electrochemical properties and safety. This review elucidates fundamentals of zinc dendritic formation and summarizes the strategies, including electrode design and modification, electrolyte optimization and separator improvement, for suppressing zinc dendritic growth.
