Combination-based nanomaterial designs in single and double dimensions for improved electrodes in lithium ion-batteries and faradaic supercapacitors

Hybrid Electrode Innovations in Triple and Quadruple Dimensions for Lithium‐Ion Batteries

“…In fact, via the operation mechanism of LIBs mentioned earlier above, it can be clearly seen that several serious anode material issues usually are related to structural collapse, unsatisfactory rate performance, large capacity decay, and large voltage hysteresis. As noted in our previous review, [15] some efforts related to the development of hybrid anodes based on the combination of two different nanomaterials have been reported. The noticed advantages arising from this design principle are undeniable.…”

“…From those observations, some early ideas for the use of hybrid nanomaterial of two or more components have been reported; a promising approach is to obtain an ideal electrode with a high specific surface area, high electronic conductivity, good mechanical, high thermal, and good chemical stabilities, low cost and environmental friendliness. In our previous review, [15] combination-based nanomaterial designs for an improved electrode in EED applications were described in detail; the hybrid designs in single and double dimensions were shown to have afforded many advantages arising from the formation of synergistic effects and positive interactions. In order to provide a fuller and deeper overview in this way, the directions and perspective of this present review will be focused on the further optimization of hybrid designs involving nanomaterial of triple and quadruple dimensions for LIB applications (Figure 2).…”

“…In a previous review article, the different hybrid architectures arising from double-dimensional nanomaterial were discussed in detail for each individual sector in the electrical energy devices (EEDs) systems, respectively. [15] It is undeniable that those different architectures have shared common significant advantages including high capacity, high availability, high energy density, high power density, and good cycling stability. Thus, in order to investigate in detail this great field, the novel synergistic effects and positive interactions in the hybridization between the triple and quadruple dimensions of nanomaterial must be further fully understood.…”

Highly Ordered TiO2 Nanotube Arrays with Engineered Electrochemical Energy Storage Performances

“…Vertically oriented self-organized TiO 2 nanotubes have become an excellent candidate material for lithium-ion battery anodes. The benefits of TiO 2 nanotube arrays are shown as follows [ 30 , 31 , 32 ]: (i) Good structural stability, large specific surface area, small volume expansion rate. (ii) With a hollow tubular structure, the gaps between tubes are conducive to the penetration of the electrolyte.…”

Poly(azomethine ether)‐derived carbon nanofibers for self‐standing and binder‐free supercapacitor electrode material applications

“…In recent decades, researches on next generation energy and associated energy storage have been actively conducted to address the global energy crisis and environmental issues 1,2 . One of the promising candidates for the next generation of energy storage devices, supercapacitors represent the intermediate characteristics of conventional capacitors and lithium–ion batteries 3‐6 . Supercapacitors are divided into electrical double‐layer capacitors (EDLCs) and pseudocapacitors, depending on the charge storage mechanism.…”
