Abstract	Improving the energy and power densities of sodium-ionbatteriesis a prime challenge to establish this energy storage technology tobe on par with state-of-the-art lithium-ion batteries. The energydensity of the sodium-ion batteries is limited due to the lower redoxpotential of their electrode materials compared to that of the correspondingLi analogues; however, it can be overcome by triggering the anionicredox. Although anionic redox has received significant research interest,a clear understanding of the underlying mechanism for delivery ofhigh capacity by utilizing anionic redox is still lacking. Formidablechallenges associated with the utilization of anionic redox such asrapid material degradation, voltage fade, and oxygen release hinderits practical applications. Given the great potential of anionic redoxchemistry for developing high-energy batteries, in this mini-review,the recent mechanistic understanding, electrode material degradationpathways including oxygen release, and strategies to trigger anionicredox are discussed. An overview of the existing potential and futureresearch directions of sodium-ion batteries involving anionic reactionis provided at the end.
