Enhancement of Li and Na Storage in Janus HfSSe Monolayers by Co-Induced Electron-Deficient Chalcogen Sites: A First-Principles Study
The growing demand for high-capacity, fast-charging, and durable rechargeable batteries has intensified the search for advanced electrode materials, with two-dimensional materials offering large surface-to-mass ratios and short ion-diffusion pathways. Here, pristine and Co-doped Janus HfSSe monolayers were investigated...
