“…The specific capacitance of 205 Fg −1 was measured, and 83% of the capacity could be maintained after 1,500 cycles and Figure 1G). Ma et al (2016) applied manganese (IV) dioxide (MnO 2 ) nanowhiskers for the decoration of carbonized ECNFs from the lignin-PVA mat, and then tested this material as an electrode material for supercapacitors. The small fiber diameters of 200 nm and the high surface area of 583 m 2 g −1 exhibited superior supercapacitor performance with a high gravimetric capacitance of 83.3 Fg −1 , as well as an energy density of 84.3 WhKg −1 and a power density of 5.72 kWkg −1 , making the material suitable for application in a high-performance supercapacitor.…”

The article summarizes the scientific progress that has occurred in the past several years in regard to the preparation of carbon nanofibers from lignin as a low-cost environmentally-friendly raw material using electrospinning. It presents an overview of using lignin, electrospinning, and carbonization to convert lignin to carbon nanofibers. Lignin is a renewable source for carbon material, and it is very abundant in nature. It is mostly produced as a byproduct from the paper industry and biomass fractionation. Despite its extensive availability and beneficial properties, only a few studies have reported on its use in electronic applications. Lignin-based carbon nanofibers have a high surface area, high porosity, and good electrical conductivity; thus, it is proposed that they are suitable for future energy storage applications.

“…Nano‐ and micro‐fibers are ‘spun’ from a polymer‐containing solution onto a target with a large potential difference, typically over 10 kV. The technique has been used to generate materials for lithium‐ion battery separators, supercapacitors, fuel cells, and, recently, RFBs ,. The advantage of using electrospun fibers in these devices is that it allows for small fiber diameters, which increase the specific surface area, and with careful variation of various parameters can allow control of porosity, fiber size and alignment.…”

Many electrochemical energy storage and conversion devices employ porous media as electrodes, gas diffusion layers or separators. Recently, electrospinning has received significant attention as a way to generate nano‐fibers of polymers with controlled morphology and properties that, once carbonised, can act as conductive and porous media for electrochemical energy devices. The recent advances in X‐ray computed tomography have led the technique to be widely used in the characterisation of energy technologies and porous media as it offers a uniquely non‐destructive insight into the 3D microstructure of materials. Here we present electrospun fibrous mats with uncontrolled, controlled and aligned morphology for use as redox flow battery electrodes and, for the first time, obtain ultra‐high resolution nano‐tomographic X‐ray imaging of the materials using a lab source. The virtual 3D volumes enable extraction of parameters that would not be possible via other characterisation routes.

“…For example, the mesoporous carbon fibers synthesized from lignin exhibited one of the highest recorded specific capacitance for biopolymer‐derived electrodes, which was ~205 F g −1 in 0.5 M Na 2 SO 4 electrolyte . A composite of MnO 2 /lignin‐derived carbon nanofibers exhibited a high capacitance as well as a good energy and power density of 84.3 W h kg −1 and 5.72 kW kg −1 , respectively . A NiO/lignin‐derived mesoporous carbon composite also showed a high specific capacitance of 880.2 F g −1 at 1.0 A g −1 along with a good cycling stability …”

Electrode and electrolyte materials with higher performance, longer life, and lower cost need to be developed, given the substantial growing demand for advanced electrochemical energy systems. Lignin, the second most abundant natural polymer, has been successfully demonstrated to be a viable precursor or feedstock for the preparation of high-performance electrochemical energy materials and components such as electrodes, electrolyte additives, membrane separators, and binders. Moreover, techno-economic analyses indicate that it is possible to prepare cost-effective carbon structures from lignin at engineering scale, in contrast with current carbon products. These facts suggest that the scalable conversion of lignin into high-value energy materials will offer a promising pathway to not only promote the utilization and valorization of lignin but also boost the development of advanced electrochemical energy systems. This review examines cutting-edge renewable energy materials derived from various lignin compounds and Review: Lignin to energy materials X Wu et al.their applications in electrochemical energy systems with an emphasis on supercapacitors, rechargeable batteries, and fuel cells. Meanwhile, this review also aims to carve out the critical barriers for lignin-derived high-performance materials for energy applications, and to identify viable approaches for the synthesis of sustainable new energy materials.
