Summary: The study investigated the importance of the preparation technique of Li4Ti5O12 (LTO) anode in a lithium-ion capacitor (LIC) application, finding significant differences in morphological properties, rate capability, and full-cell cycle life performance. The best-performing LIC was influenced by the LTO anode with the least charge transfer and diffusion resistances, prepared using a surfactant, due to its small particle size, good dispersion, and high specific surface area. This highlights the crucial role of synthesis technique choice in the overall performance of LIC materials.
