Partial Occupation of Selenium in Porous Carbon Enhanced Selenium Utilization for Potassium-ion Batteries

Key Points

• The study aims to improve selenium loading efficiency in potassium-ion batteries by using a novel porous carbon structure.
• Developed a hierarchical carbon structure from Zn-HKUST for selenium loading.
• Employed a partial-occupation method to load selenium into micropores while leaving mesopores empty.
• Evaluated battery performance and efficiency based on the new carbon architecture.
• Achieved higher selenium utilization rates compared to conventional methods.
• Demonstrated enhanced electrochemical performance in potassium-ion batteries using the Se/C PSC structure.
