A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

One‐Pot Spray Pyrolysis Fabrication of Multi‐Phase Lithium Manganese Oxide Microsphere Cathodes for Enhanced Lithium‐Ion Battery Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

Unraveling Synergistic Regulation Mechanism in Nitrogen/Sulfur Co‐Doped Biomass‐Derived Hard Carbon Toward Durable Sodium‐Ion Battery Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nitrogen/sulfur co‐doping optimizes the electron and spatial structure of biomass‐derived hard carbon, and the anode demonstrates superior long‐term cycling stability over 2000 cycles, validating an improved “adsorption‐intercalation‐pore filling” mechanism.
