“…Nonmetallic cations, e.g., proton (H + ), hydronium (H 3 O + ), and ammonium (NH 4 + ) ions, have rarely been regarded as charge carriers in aqueous battery chemistry for research and commercial applications, [ 1–3 ] where the mainstream attention located at the metal cations, such as Li + , Na + , Zn 2+ , and Al 3+ ions. [ 4–8 ] Most recently, Ji and co‐workers have pioneeringly reported several typical aqueous batteries utilizing H + and NH 4 + as charging carriers with outstanding electrochemical performance, especially for the ultrafast kinetics with high power density. [ 1,9 ] It could be ascribed to (1) nondiffusion‐controlled topochemistry between nonmetallic charging carriers and electrode framework during insertion/extraction process, resulting in pseudocapacitive‐dominated behavior; [ 1,9 ] (2) the lower molar mass and smaller hydrated ionic size of such non‐metallic charging carriers, which could result in fast diffusion in aqueous electrolytes.…”

Nonmetallic ammonium (NH4+) ions are applied as charge carriers for aqueous batteries, where hexagonal MoO3 is initially investigated as an anode candidate for NH4+ storage. From experimental and first‐principle calculated results, the battery chemistry proceeds with reversible building–breaking behaviors of hydrogen bonds between NH4+ and tunneled MoO3 electrode frameworks, where the ammoniation/deammoniation mechanism is dominated by nondiffusion‐controlled pseudocapacitive behavior. Outstanding electrochemical performance of MoO3 for NH4+ storage is delivered with 115 mAh g−1 at 1 C and can retain 32 mAh g−1 at 150 C. Furthermore, it remarkably exhibits ultralong and stable cyclic performance up to 100 000 cycle with 94% capacity retention and high power density of 4170 W kg−1 at 150 C. When coupled with CuFe prussian blue analogous (PBA) cathode, the full ammonium battery can deliver decent energy density 21.3 Wh kg−1 and the resultant flexible ammonium batteries at device level are also pioneeringly developed for potential realistic applications.

The development of new battery technology that utilizes abundant electrode materials that are environmentally benign is an important area of research. To alleviate the reliance on Li‐ion batteries new energy storage mechanisms are urgently needed. To address these issues, MnO2 nanowires were investigated as a possible electrode material for use in rechargeable Al ion batteries that can operate in aqueous conditions. The use of this type of material and an aqueous electrolyte ensures safe operation as well as easy recycling of spent batteries. A potassium‐rich cryptomelane structure was presented, and a new mechanism of electrochemical energy storage was elucidated based on the intercalation and deintercalation of small‐radius Al3+ ions interchanging with larger K+ ions in the cryptomelane MnO2 nanowires, which was supported by DFT calculations. This first‐time use of a cryptomelane MnO2 cathode for an aqueous Al ion system yielded a discharge capacity of 109 mAh g−1, which indicates the potential commercial viability of rechargeable aqueous Al‐ion batteries.

Aqueous aluminum‐ion batteries are at an early development stage and there is a need to discover new electrode materials for the fabrication of high energy density devices. To address this issue, we investigate MoO3 nanowires as a possible electrode material for use in rechargeable Al‐ion batteries that can operate in aqueous conditions. We present a hexagonal structure of MoO3 microrods as an Al‐ion intercalation host material and show its first‐time use as a potential electrode for an aqueous Al‐ion battery system. This yields a discharge capacity of approximately 300 mAh g−1 for 150 cycles and around 90 % retention after 400 cycles at a current density of 3 A g−1. The utilization of this type of material and aqueous electrolytes guarantees both safety during operation and simple recycling of spent batteries.
