Aqueous energy storage systems based on ammonium-ion (NH4+) as charge carrier have attracted increasing interest owing to their great potential for large-scale application. Developing suitable cathodes (especially binder-free electrodes) for excellent NH4+ storage is still in their infancy....

During the development of high-capacity, ultra-stable battery electrode materials, battery performance, and safety issues are proved to be related to the properties of the electrolyte used. The employment of electrolyte additives is to improve the battery electrolyte properties. Representative...
