NASA的喷气式发动机实验室推出一种纤维用来烧结多孔电极。用烧结一种能制备纤维的垫层的方法,因交叉的纤维之间的结合能够增强其电导率,提供其强度,仍能使垫层具有高孔隙度。 首先,将微细粉末电极材料在能迅速固化的液体粘合剂、增塑剂和溶剂溶液中悬浮,并将这种混合物通过细小的喷嘴迫使成为纤维状,如同从熔化的糖中制出棉花糖一样。然后,将纤维热解使其挥发物挥发掉,最后剩下纯电极材料,再把该纤维截 NASA’s Jet Engine Laboratory introduces a fiber that is used to sinter porous electrodes. By sintering a mat that can be made into fibers, the strength of the mat can be enhanced due to the bonding between the intersecting fibers, still giving the mat a high degree of porosity. First, the finely powdered electrode material is suspended in a rapidly curable liquid binder, plasticizer, and solvent solution and the mixture is forced through a fine nozzle into a fibrous form, just as cotton candy is made from melted sugar same. Then, the fiber is pyrolyzed to volatilize its volatiles, and finally the pure electrode material remains, and then the fiber is cut
