Aqueous sodium-ion batteries have attracted extensive attention for large-scale energy storage applications, due to abundant sodium resources, low cost, intrinsic safety of aqueous electrolytes and eco-friendliness. The electrochemical performance of aqueous sodium-ion batteries is affected by the properties of electrode materials and electrolytes.
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.
We apologise for any inconvenience this might cause and thank you for your patience. Rechargeable aqueous sodium-ion batteries have become promising candidates for electrochemical grid-scale energy storage systems because of the rich natural abundance of sodium and the favourable safety of aqueous electrolytes.
2.1. The revival of room-temperature sodium-ion batteries Due to the abundant sodium (Na) reserves in the Earth’s crust (Fig. 5 (a)) and to the similar physicochemical properties of sodium and lithium, sodium-based electrochemical energy storage holds significant promise for large-scale energy storage and grid development.
Aqueous rechargeable sodium ion batteries (ASIBs) are low-cost and highly safe, which deserves more research in electrochemical energy storage systems. However, the developments of ASIBs are limited by its narrower thermodynamic voltage window (1.23 V) and lower energy density compared to the organic system.
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.
