摘要
Exploring novel low-cost cathodes for sodium-ion batteries, here we unveil beta-Na2MnP2O7, a new pyrophosphate cathode. Stabilizing into a triclinic structure, it was found to be electrochemically active, delivering a discharge capacity approaching 80 mA h g(-1) along with the highest ever Mn3+/Mn2+ redox potential located at 3.6 V.
