“…Ov‐NiMn LDH exhibits the outstanding specific capacitance of 1183 C g −1 at 1 A g −1 and excellent capacitance retention of 70.58% at 10 A g −1 . Similarly, Feng et al [ 76 ] prepared oxygen vacancy‐rich NiCo LDH as the positive electrode material by the reduction of NaBH 4 . It also exhibits the superior specific capacitance of 1563.1 F g −1 at 1 A g −1 .…”

“…Wu et al fabricated nickel-cobalt layered double hydroxide as a cathode material, which exhibited 2682 F g −1 at a current density of 3 A g −1 [14]. In another work, Liang et al [15] fabricated an oxygen vacancy-rich nickel-cobalt layered double hydroxide electrode that demonstrated 1563 F g −1 capacitance at a current density of 1 A g −1 . However, the common properties of metal-based positive electrode materials are that they work within small potential ranges (0-0.5/6 V) [14][15][16][17].…”

The development of smart negative electrode materials with high capacitance for the uses in supercapacitors remains challenging. Although several types of electrode materials with high capacitance in energy storage have been reported, carbon-based materials are the most reliable electrodes due to their high conductivity, high power density, and excellent stability. The most common complaint about general carbon materials is that these electrode materials can hardly ever be used as free-standing electrodes. Free-standing carbon-based electrodes are in high demand and are a passionate topic of energy storage research. Electrospun nanofibers are a potential candidate to fill this gap. However, the as-spun carbon nanofibers (ECNFs) have low capacitance and low energy density on their own. To overcome the limitations of pure CNFs, increasing surface area, heteroatom doping and metal doping have been chosen. In this review, we introduce the negative electrode materials that have been developed so far. Moreover, this review focuses on the advances of electrospun nanofiber-based negative electrode materials and their limitations. We put forth a future perspective on how these limitations can be overcome to meet the demands of next-generation smart devices.

The development of smart negative electrode materials with high capacitance for use in supercapacitors remains challenging. Although there have been several types of electrode materials with high capacitance used in energy storage, carbon-based materials are the most reliable electrodes due to their high conductivity, high power density and excellent stability. The most common complaint about general carbon materials is that these as-formed electrode materials can hardly ever be used as free-standing electrodes. Free-standing carbon-based electrodes are in high demand and are a passionate topic of energy storage research. Electrospun nanofibers are a potential candidate to fill this gap. However, the as-spun carbon nanofibers (ECNFs) have low capacitance and energy density on their own. To this end, several attempts have been made to improve these characteristics. In this review, we introduce negative electrode materials that have been developed. Moreover, this review places special attention to the advances of electrospun nanofiber-based negative electrode materials and their limitations. Based on the above information, we put forth a future perspective on how these limitations can be overcome to meet the demands of next-generation smart devices.
