Electrochemical energy storage technology is of critical importance for portable electronics, transportation and large-scale energy storage systems. There is a growing demand for energy storage devices with high energy and high power densities, long-term stability, safety and low cost. To achieve these requirements, novel design structures and high performance electrode materials are needed. Porous 1D nanomaterials which combine the advantages of 1D nanoarchitectures and porous structures have had a significant impact in the field of electrochemical energy storage. This review presents an overview of porous 1D nanostructure research, from the synthesis by bottom-up and top-down approaches with rational and controllable structures, to several important electrochemical energy storage applications including lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, lithium-oxygen batteries and supercapacitors. Highlights of porous 1D nanostructures are described throughout the review and directions for future research in the field are discussed at the end.

“…The N 1 s high resolution spectrum can be assigned to four peaks: Pyridinic N (N-6), pyrrolic N (N-5), quaternary N (N-Q), and pyridine-N-oxide (N-X) (inset Figure 6b). As shown in Figure 7, the chemical forms of N in nitrogen doped carbon materials have been proposed by research groups [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. N-Q can offer highly active sites, and N-6 and N-5 can improve the wettability of carbon material to increase the effective specific surface area for double layer formation.…”

“…Based on previous reports [18][19][20][21][22], the nitrogen-containing functional groups can provide a pair of electrons to change the electron donor/acceptor characteristic of carbon materials [8,9,13]. The nitrogen containing functional groups can improve the wettability of carbon material to increase the effective specific surface area for double layer formation and offer extra redox reactions, producing more pseudocapacitance [8][9][10][11][12][13][14]. The charge storage capability of carbon materials also depends primarily on their textural behavior except the surface chemistry [16,22].…”

“…Recently, nitrogen-doped carbon materials have been widely applied to the fuel cell [1], solar cell [2], lithium-ion battery [3], lithium air battery [4], electrocatalysis [5], and adsorption [6,7]. Various nitrogen-doped carbon materials [8][9][10][11][12][13][14][15][16][17], such as carbon nanotube [9][10][11][12], porous carbons [13], nanofiber [14], and graphene [15], have been investigated for supercapacitor electrode materials. As we know, electrode material is the key component of electrochemical capacitors and the role of efficient charging of the electrode/electrolyte interface by ions is essential.…”

Nitrogen-doped carbon materials derived from N-containing conducting polymer have attracted significant attention due to their special electrochemical properties in the past two decades. Novel nitrogen-enriched carbon nanofibers (NCFs) have been prepared by one-step carbonization of p-toluene sulfonic acid (P-TSA) doped polyaniline (PANI) nanofibers, which are successfully synthesized via the rapid mixing oxidative polymerization at room temperature. NCFs with diameters ranging from 100 nm to 150 nm possess a highly specific surface area of 915 m 2 g −1 and a relatively rich nitrogen content of 7.59 at %. Electrochemical measurements demonstrate that NCFs have high specific capacitance (172 F g −1 , 2 mV s −1 ) and satisfactory cycling stability (89% capacitance retention after 5000 cycles). The outstanding properties affirm that NCFs can be promising candidates for supercapacitor electrode materials. Interestingly, the carbonization of PANI opens the possibility to tailor the morphology of resulting nitrogen-enriched carbon materials by controlling the reaction conditions of PANI synthesis. products of PANI (15 wt % N, 79 wt % C) have been successfully employed in other articles as electrode materials [29][30][31][32][33][34][35][36]. However, most of the present reported PANI-derived carbon materials are irregular and agglomerate. Furthermore, the PANI-derived carbon materials by one-step carbonization usually have a low specific surface area while the chemical activation process is complex and increases costs. Recently, one-dimensional (1D) nanostructured PANI, such as nanofibers, nanotubes, nanowires, and nanorods, have attracted intensive attention for their unique structure, properties, and new potential applications [37][38][39][40][41][42]. Various methods, such as hard or soft template [32,39], interfacial polymerization [40], and rapid mixing polymerization, have been used to tailor the morphology of the products in the chemical oxidative polymerization. Compared with other methods, the rapid mixing polymerization method is the most common non-template route to produce PANI nanofibers owing to its simplicity, cost effectiveness, being environmental friendly, and pure production [43][44][45][46][47].Furthermore, the molecular structure and functional groups of doped acids also influence the morphology and structure of resulting PANI particles [28,41,[47][48][49][50][51][52]. Chutia's work investigates the effect of organic camphorsulfonic acid (CSA) and inorganic hydrochloric acid (HCl) on the structures and conductivity of polyaniline, and the discovery indicates that PANI nanorods doped with CSA produce more uniform and aligned structures [50]. Organosulfonic acid possessing long alkyl-chain sulfonic acids, such as p-toluenesulfonic acid (P-TSA), β-naphtalenesulfonic acid (NSA), camphorsulfonic acid (CSA), and dodecyl benzene sulfonic acid (DBSA), have already been explored by some researchers [49,51]. P-TSA (the molecular structural formula is p-CH 3 C 6 H 4 SO 3 H) is a non-oxidizing organic acid, so...

“…Here, the surfactant, or micelles of the surfactant, acts as a porogen, where its removal via leaching from the polymer matrix leaves behind cavities that increase the pore volume, and in turn the specific surface area, of the fibers. 141,257,258 In polymernanoparticle composites, the use of surfactant porogens can help to better expose embedded nanomaterials to targets dissolved in water, increasing uptake and improving sorbent capacity.…”
