Insight into the electrolyte strategies for aqueous zinc ion batteries

Nickel ferrocyanides for aqueous ammonium ion batteries

“…The variation of plateau for these samples is attributed to the synergistic effects of the introduction of sodium and composition of the cubic phase and rhombohedral phase as mentioned above. With regard to the electrochemical capacity, for Na 0.5 Ni 1.75 Fe(CN) 6 , NaNi 1.5 Fe(CN) 6 , and Na 1.5 Ni 1.25 Fe(CN) 6 , their capacities depend on the corresponding formula weight. An increase of sodium content causes a decrease of formula weight, so that the capacity is improved and Na 1.5 Ni 1.25 Fe(CN) 6 provides the highest capacity among them.…”

“…1 Following the working mechanism as "Rocking-Chair" type lithium ion batteries, ammonium ion batteries, as the next generation secondary batteries, have enormous potential for future energy storage applications owing to their safety and unlimited raw resources of hydrogen and nitrogen. [2][3][4][5][6][7][8] Consequently, lots of framework materials have been explored extensively and some of them are identified as electroactive materials for ammonium ion batteries, e.g. transition metal oxides, [9][10][11][12] organic compounds, [13][14][15] and metal organic frameworks.…”

Recent Advance and Modification Strategies of Transition Metal Dichalcogenides (TMDs) in Aqueous Zinc Ion Batteries

“…Due to the deterioration of the environment and the deficit of fossil energy, it is increasingly important to develop environmentally friendly, sustainable, and renewable energy [ 1 , 2 , 3 ]. At present, some renewable energy power generation can meet the requirements of environmental protection and sustainable development, such as solar power, wind power, and tidal power generation, but these energy sources suffer from regional limitations and instability, limiting their wider application.…”

Optimizing NH4+ Storage Capability of Nickel Ferrocyanide by Regulating Coordination Anion in Aqueous Electrolytes

“…[1][2][3] Traditional lithium ion batteries are qualified for this practical application but encounter the scarcity of lithium minerals and the increasing price. [4][5][6][7][8] As an alternative battery chemistry, aqueous ammonium ion batteries (AAIBs) based on NH 4 + as charge transfer ion have been of growing concern owing to the infinite abundance, wide availability, and cost effectiveness of nitrogen and hydrogen resources. [9][10][11][12] Besides, the replacement of organic electrolyte by aqueous electrolyte exhibits some features including nonflammable, green, simple synthesis, and high ionic conductivity, embodying the thought of sustainable chemistry.…”

“…The large requirement for storing renewable energy from solar or wind calls for safe, low‐cost, and high‐performance rechargeable batteries [1–3] . Traditional lithium ion batteries are qualified for this practical application but encounter the scarcity of lithium minerals and the increasing price [4–8] . As an alternative battery chemistry, aqueous ammonium ion batteries (AAIBs) based on NH 4 + as charge transfer ion have been of growing concern owing to the infinite abundance, wide availability, and cost effectiveness of nitrogen and hydrogen resources [9–12] .…”
