“…At a 0.5 C charge/ discharge rate, the material demonstrates superb stability with 95% capacity retention and a coulombic efficiency exceeding 99% after 450 cycles. In comparison, current graphite anodes show a capacity loss of~65% under similar testing conditions [43]. The electrospun anode is also physically stable in a battery environment.…”

“…Layered hydrogen titanates also deliver pseudocapacitive behavior in both nanotube and nanowire forms, [316,317,328] which have an open layered structure with large interlayer spacing (0.8 nm) and enable fast Li + ion intercalation. [330][331][332][333][334][335][336][337][338] Nitrogen-rich CNT/C composites were tested as electrodes in lithium ion capacitors (LICs), and demonstrated a capacity of >200 mAh g −1 for 600 cycles. Similar results have been observed with sodium titanate in non-aqueous electrolytes.…”

“…Layered H 2 Ti 3 O 7 nanotubes synthesized through hydrothermal exhibited 82% of the initial capacity remaining after 1000 cycles and showed pseudocapacitive features in CV curves. [330] To improve the capacitance of the anode, porous VN nanowirereduced graphene oxide composites (VN-RGO) were developed by Wang et al (Figure 24d,e). [329] Comparing the performance of sodium titanate nanotubes to nanorods, pseudocapacitive behavior is more obvious in the former, owing to more active sites in the nanotubular structure.…”

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.

“…Five to ten times higher energy density than in conventional electrical double-layer capacitors (EDLCs) can be obtained from LICs with their existing benefits of high power density and long cycle life [1,2]. Therefore, LICs have wide potential applications, such as in renewable power generation systems, power backup systems, and energy recovery systems in industrial machinery.…”
