Figure 7. (A) SEM image of MnO2; (B) CV curves of Zn/MnO2 and Zn-LSO-1/MnO2 cells at a scanning rate of 0.2 mV s-1; (C) galvanostatic charge and discharge potential profiles and (D) cycling stability performance of Zn/MnO2 and Zn-LSO-1/MnO2 cells at a current density of 1 A g-1. LSO: Lithium polysilicate; SEM: Scanning electron microscope; CV: Cyclic voltammetry.
