Abstract
By applying the annealing step during the solid-state synthesis, well-crystallized spinel LiMn<sub>2</sub>O<sub>4</sub> with high phase purity was fabricated. The sensitive effect of heating procedure on the structural and electrochemical properties of LiMn<sub>2</sub>O<sub>4</sub> product was investigated. It was found that preheat-treatment-calcinations-annealing process can effectively eliminate the impurity phase. The post-annealing process also leads to a better crystalline and suitable strain for the LiMn<sub>2</sub>O<sub>4</sub> product, which contributes to the enhanced cycling performance.
