3d orbital electron tunning and crystal engineering enables high-capacity vanadium oxide for aqueous ammonium ion batteries

Tzu‐Hao Lu, Qiyu Liu, Ang Yi, Hao Liu et autres

Vanadium pentoxide (V2O5) has shown great potential as the electrode for aqueous ammonium ion batteries (AAIBs) owing to its good electrochemical reversibility and high theoretical capacity. However, the electrochemical performance of V2O5 is seriously limited by the weak NH4+ adsorption capability and …

Carbon‐anchored Sb nanoparticles as high‐capacity and stable anode for aqueous alkaline batteries

Yanxia Yu, Ruofei Qin, Xin Shi, Jinhao Xie et autres

Abstract Antimony (Sb) holds a high theoretic capacity and suitable redox potential as a promising anode for aqueous alkaline batteries (AABs). However, the uncontrollable nucleation for SbO2− and promiscuous water‐induced side reactions severely degrade the reversibility of Sb anode. Herein, the carbon‐anchored …

Valence Engineering Enhancing NH4+ Storage Capacity of Manganese Oxides

Tzu‐Hao Lu, Chenghui Zeng, Haozhe Zhang, Xin Shi et autres

Abstract Ammonium ions (NH4+), as non‐metallic charge carriers, are attracting attention in aqueous batteries due to its low molar mass, element sufficiency, and non‐toxicity. However, the host materials for NH4+ storage are still limited. Herein, an oxygen defects‐rich manganese oxide (MnO2–x) for …
