Dataset for: Cobalt Doping Enables High-Performance MoSe2 and WSe2 Anodes for Lithium-Ion Batteries

This dataset contains the experimental data supporting the study "Cobalt Doping Enables High-Performance MoSe2 and WSe2 Anodes for Lithium-Ion Batteries". The deposited data include X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, rate-performance measurements, long-term cycling data, and differential-capacity profiles for pristine and Co-doped MoSe2 and WSe2. The dataset supports the investigation of cobalt-induced structural and electronic changes and their influence on lithium-storage performance. Co incorporation improves the electrochemical performance of both transition-metal dichalcogenides, with a particularly pronounced enhancement in Co-doped WSe2 under high-rate conditions, whereas Co-doped MoSe2 exhibits an unusual initial capacity decay followed by gradual capacity recovery during prolonged cycling.
