With abundant reserves, safe properties, and a superior electrochemical rate, sodium-ion batteries (SIBs) are expected to be widely used in large-scale energy storage applications. Searching for a cost-effective, long cycle life, and high-capacity sodium storage electrode material is the key to realizing the large-scale applications of SIBs.
Because of abundant sodium resources and compatibility with commercial industrial systems 4, aqueous sodium-ion batteries (ASIBs) are practically promising for affordable, sustainable and safe large-scale energy storage.
Due to the wide availability and low cost of sodium resources, sodium-ion batteries (SIBs) are regarded as a promising alternative for next-generation large-scale EES systems.
Aqueous sodium-ion batteries show promise for large-scale energy storage, yet face challenges due to water decomposition, limiting their energy density and lifespan. Here, the authors report a cathode surface coating strategy in an alkaline electrolyte to enhance the stability of both electrolyte and battery.
As a candidate for secondary battery in the field of large-scale energy storage, sodium-ion batteries should prioritize their safety while pursuing high energy density. In general, NFOLEs contains high content of phosphides and fluorides.
Concurrently Ni atoms are in-situ embedded into the cathode to boost the durability of batteries. Aqueous sodium-ion batteries show promise for large-scale energy storage, yet face challenges due to water decomposition, limiting their energy density and lifespan.
