High-voltage and low-cost manganese-based P 2-type oxides show real promise as promising cathode for sodium-ion batteries (SIBs). But the P2 − O2 phase transformation and Na + /vacancy ordering results in the inferior structural stability and Na + diffusion coefficient, which further leads to rapid decay of capacity and poor rate capability.
Lithium-oxygen (Li-O2) batteries have attracted much attention owing to the high theoretical energy density afforded by the two-electron reduction of O2 to lithium peroxide (Li2O2). We report an in...
