A review on advancement and future perspective of 3D hierarchical porous aerogels based on electrospun polymer nanofibers for electrochemical energy storage application

Template-Induced Ni(OH)2 Nanosheet-Constructed Hierarchically Porous Aerogel Boosts Superior Specific Capacitance and Rate Performance for Supercapacitors

“…Aerogels as a kind of porous materials have a high specific surface area, plentiful porosity (>80%), 3D interconnected network, and abundant pore structure. 26,27 These features provide rich electrochemical active sites, suitable channels to facilitate the entry and transfer of electrolyte ions, and decrease the diffusion length of electrolyte ions. 28,29 At present, metal oxide/hydroxide aerogels, carbon aerogels, and composite aerogels prepared by various methods have been extensively studied.…”

Preparation of multifunctional Ag@PAN/PBA nanofibrous aerogel membranes for efficient PM 0.3 capture and effective antibacterial activity

“…More recently, 3D electrospun nanofibrous aerogels (NFAs) with continuous open-cell cellular structure have been extensively used as a new class of advanced porous materials in various applications, such as in thermal insulation, sensors, catalyst support, adsorbent, energy storage, and air filtration. [30][31][32][33][34] Compared with conventional 2D fibrous air membranes, the greater internal volume and higher porosity allow the 3D NFAs to achieve high filtration efficiency for PM 2.5 with lower ΔP and longer lifetime. For instance, Adlhart et al synthesized ultralight NFAs with a high dust loading capability using a solid-templating technique and studied the relationship between the filtration performance and specific volume of secondary pores.…”

B, O and N Codoped Biomass-Derived Hierarchical Porous Carbon for High-Performance Electrochemical Energy Storage

“…The unique 3D microstructure of hierarchical porous carbons comprises macropores, mesopores and micropores. Micropores provide more electrolyte-ion-adsorption sites; macropores and mesopores can reduce the diffusion distance and diffusion resistance, respectively, which is conducive to the diffusion of the electrolyte, thereby increasing the power density of the electrode material [ 11 ]. Therefore, choosing a reasonable preparation method and activator to obtain hierarchical porous carbon is the focus of research.…”
