摘要

The cells applied with a three-dimensionally (3D) patterned Li_4Ti_5O_(12) (LTO) electrode showed good performance as a rechargeable lithium-ion battery. The 3D-pattemed electrode was fabricated with a printing apparatus and has many lined patterns with a high aspect ratio standing in line on a current collector. The cell using 3D-patterned electrode showed much better rate capability than that using a conventional flat electrode. In this research, cyclic voltammetry was carried out to investigate the mechanism realizing the high rates of charging and discharging in 3D-patterned electrode. Various types of line patterns were fabricated for 3D electrode by using LTO electrode slurry, and the influences of basic specifications of electrode structure (the space between two neighboring electrode lines, the height and width of electrode) on the charge and discharge characteristics were evaluated to optimize the electrode pattern. In addition, the electrode performance was discussed from the viewpoints of ohmic resistance and charge-transfer resistance of the cells with 3D-patterned and conventional flat electrodes.
