Cement solid electrolyte with porous structure as well as preparation method and application of cement solid electrolyte
The invention relates to a porous structure cement solid electrolyte and a preparation method and application thereof. A chemical foaming method is adopted, potassium iodide serves as an exciting agent, hydrogen peroxide serves as a foaming agent, the cement solid electrolyte with the three-dimensional porous structure is synthesized, the pore structure is effectively regulated and controlled, the ionic conductivity of the electrolyte is improved, and interface contact is improved. And then assembling the porous cement solid electrolyte and the reduced graphene oxide composite material into a symmetrical cement structure supercapacitor, wherein the area specific capacitance is 351.5 mF/cm < 2 > when the current density is 0.5 mA/cm < 2 >. When the power density is 110.6 W/kg, the energy density is 21.6 Wh/kg, when the power density is increased to 1106.2 W/kg, the energy density can still be kept 13.8 Wh/kg, and after 5000 times of constant-current charging and discharging are conducted under the current density of 10 mA/cm < 2 >, the area specific capacitance retention rate reaches up to 93.8%.
