Porous organic polymer/RGO composite as high performance cathode for half and full sodium ion batteries

Novel porous Na2PDHBQS/RGO composite has been prepared and investigated as a cathode for sodium ion batteries in ether-based electrolyte with excellent cycle stability and rate performances. The full cell of Na2PDHBQS/RGO-Na2TP delivers an initial reversible capacity of 210 mAh g−1, indicating its promising potential for practical applications.364
