Abstract
Anode-free sodium batteries (AFSBs) with near-theoretical energy density hold great promise for next-generation sustainable energy storage systems. However, their practical implementation is impeded by the low operating rate threshold (<1 milliampere per square centimeter) and poor cycling stability, owing to dendritic sodium (Na) growth. Here, a high-rate and durable AFSB is successfully realized via a spatially anion-confined electrolyte strategy. Specifically, positively charged nanoparticles are introduced into the electrolyte to selectively anchor anions, generating localized contact ion pair–dominated solvation to facilitate rapid Na + desolvation at electrode interface and form an anion-derived solid…
