Electrochemical Energy Storage Properties of High-Porosity Foamed Cement
Foamed porous cement materials were fabricated with H(2)O(2) as foaming agent. The effect of H(2)O(2) dosage on the multifunctional performance is analyzed. The result shows that the obtained specimen with 0.6% H(2)O(2) of the ordinary Portland cement mass (PC0.6) has appropriate porosity, leading t...

description | Foamed porous cement materials were fabricated with H(2)O(2) as foaming agent. The effect of H(2)O(2) dosage on the multifunctional performance is analyzed. The result shows that the obtained specimen with 0.6% H(2)O(2) of the ordinary Portland cement mass (PC0.6) has appropriate porosity, leading to outstanding multifunctional property. The ionic conductivity is 29.07 mS cm(−1) and the compressive strength is 19.6 MPa. Furthermore, the electrochemical energy storage performance is studied in novel ways. The PC0.6 also shows the highest areal capacitance of 178.28 mF cm(−2) and remarkable cycle stability with 90.67% of initial capacitance after 2000 cycles at a current density of 0.1 mA cm(−2). The superior electrochemical energy storage property may be attributed to the high porosity of foamed cement, which enlarges the contact area with the electrode and provides a rich ion transport channel. This report on cement–matrix materials is of great significance for large scale civil engineering application. |
