Comparative Study of Novelty Thin-films for Li-ion Batteries

Abstract

The development of Li-ion batteries leads to high-density Li-ion battery technology as a storage system. to realize a Li-ion battery with a high energy density is to modify its anode, called a thin-film anode. The anode used is coated with a material thickness of 10 mm, increasing the cathode material that can be accommodated in one cell. This study aimed to analyze the Cu-powder and LTO materials used in Thin-film Li-ion batteries as a substitute for graphite because they offer higher capacity, chemical stability, fast charging technology (LTO), cheap, and environmentally friendly (Cu-powder). Based on XRD and FTIR tests, the material has a good crystal structure, and not many impurities are still contained in it. The SEM results showed that both particles showed uniformity in the shape of a single particle and were strengthened by the SEM-EDX test to review the quantity of each element present in the two materials. The electrochemical test results showed that Cu-powder material was better, with a specific capacity of 144.82 mAh g-1, higher than LTO (81.04 mAh g-1).
