Cement-based supercapacitor improved by using active carbon fibers
The invention relates to a cement-based supercapacitor improved by using active carbon fibers, which is prepared by matching a base material with an ionic phase, a conductive phase, a toughening phase and a binding agent for use, and is high in electrochemical activity and good in voltage resistance and impact resistance. The carbon fiber with the great length-diameter ratio is used for replacing lamellar carbon powder and expensive graphene, the carbon fiber is a conductive phase and a toughening phase, and the carbon fiber is matched with a proper amount of a sucrose solution and aramid fiber, so that good compression resistance and impact resistance effects are achieved; the carbon fiber and the metal salt solution are mixed and then sintered, active metal on the surface of the carbon fiber is reinforced and effectively prevented from being lost, a large number of hole structures appear on the surface of the sintered carbon fiber due to oxidation etching, the ionic conductivity is improved, and the electrochemical performance of the capacitor is further effectively improved; the raw materials used in the invention are low in price, the preparation process is simple and easy to implement, and the prospect of early realization of energy storage/building integration practical application of the cement-based supercapacitor is broadened.
本发明涉及一种利用活性碳纤维改良的水泥基超级电容器，通过基体材料与离子相、导电相、增韧相、结合剂的配合使用，制备一种电化学活性强、耐压、耐冲击性良好的水泥基超级电容器。用长径比极大的碳纤维替代片层状碳粉和价格昂贵的石墨烯，碳纤维既是导电相、也是增韧相，配合适量的蔗糖溶液和芳纶纤维，起到良好的抗压、抗冲击作用；碳纤维与金属盐溶液混合后再烧结，使碳纤维表面活性金属被“加固”，有效防止其流失，烧结后的碳纤维表面因氧化刻蚀出现大量孔洞结构，利于提高离子电导率，进而有效提高电容器的电化学性能；本发明所用原料价格低廉、制备工艺简单易行，为水泥基超级电容器早日实现“储能/建筑一体化”实际应用拓宽了前景。
