Abstract

Microarray electrodes of LiMn₂O₄ and Li_4/3Ti_5/3O₄ were prepared on a glass substrate using a sol-gel method. The prepared LiMn₂O₄ and Li_4/3Ti_5/3O₄ microarray electrodes were characterized with scanning electron microscopy, Raman spectroscopy, and cyclic voltammetry. Using a polymer-gel electrolyte, lithium ion microbattery of Li_4/3Ti_5/3O₄/polymer-gel/LiMn₂O₄ (cell area: 6.6 × 10^-2 cm²) was successfully constructed. The microbattery operated reversibly at 2.5 V, and the discharge capacity was 300 nA h, which corresponded to an energy density of 11 μW h cm^-2.
