Abstract

Low-temperature growth of idiomorphic spinel-type Li_1+xMn _2-xO₄ (x = 0.09, 0.14) crystals was achieved by using a LiCl-KCl flux. The flux growth driven by rapid cooling resulted in truncated octahedral Li_1+xMn_2-xO₄ crystals surrounded by both dominating {111} and minor {100} faces. The chemical compositions, sizes, and shapes of the Li_1+xMn_2-xO₄ crystals could be tuned by simply changing the growth conditions. Among the various products, the crystals grown at a low temperature of 600 °C showed a small average size of 0.2 μm. The small Li_1+xMn_2-xO₄ crystals grown at 600 °C showed better rate properties than the large crystals grown at 900 °C, when used as a positive active material in lithium-ion rechargeable batteries.
