Conducted a series of precise procedures for the synthesis of materials using solvothermal techniques. Utilized a glove box to ensure an inert environment, carefully mixing and preparing precursors like carbon and lithium. The reaction was carried out under controlled heating, followed by an extensive acid-washing process. The final product underwent multiple centrifugation and ultrasonic treatments to achieve purity. The research emphasized meticulous handling and processing, resulting in high-quality material preparation for further study.
