Abstract
Sodium Storage In article number 2309701, Xifei Li, Mingjun Wang, and co-workers report that the electron spin state of Na4Fe3(PO4)2P2O7 cathode can be optimized from low-spin to medium-spin via Mn/F dual-doping, thus decreasing the band gap and increasing the electronic conductivity of the material, which thereby results in superior sodium storage.
