Improving energy d. while maintaining power d. and cycle stability is the most serious challenge for supercapacitors. The solid active electrode material might possess a higher redox species d. compared with its traditional counterpart, however, its electrochem. reaction kinetics is several magnitude orders lower in solids than that in liquids, leading to a deterioration of power d. Thus, a new approach based on 3-TEMPO-1-methylylimidazolium bromide (MIm+-TEMPO• Br-) biredox electrolyte, and a PANI-gel network modified carbon paper (PNcp) electrode for supercapacitor were developed. The biredox electrolyte possesses a high energy d. comparable to solid redox materials and a fast kinetics of liquid redox reaction, while the cross-diffusion of ions leads to a serious voltage drop which presents an inherent self-discharge problem. Fortunately, the PNcp prepared by a millisecond photo-thermal process makes up for this shortcoming. On one hand, its unique PANI-gel network structure protects the biredox electrolyte from cross-diffusion phenomenon, however, the combination of doping/dedoping process of PANI and redox process of MIm+-TEMPO• Br- provides an extra effect to prevent the self-discharge and attain a synergetic electrochem. performance. This method explores an avenue to pursue for battery level energy d. meanwhile maintains good power d. In addition to this study using 1,4-Bis(bromomethyl)benzene, there are many other studies that have used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5SDS of cas: 623-24-5) was used in this study.
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. SDS of cas: 623-24-5 Due to the reactivity of bromide, they are used as potential precursors or important intermediates in organic synthesis.
