Li–Na metal compounds inserted into porous natural wood as a bifunctional hybrid applied in supercapacitors and electrocatalysis

Sophora-like Nickel–Cobalt Sulfide and Carbon Nanotube Composites in Carbonized Wood Slice Electrodes for All-Solid-State Supercapacitors

“…Increasing the energy density of SCs through a reasonable design of electrode material structure and composition is a key factor in realizing the industrialization of SCs. − Wood is a renewable material with an oriented tracheid structure. After carbonization and activation, the tracheid structure can still be integrally retained, − which was ideally fitted for fast mass transport along the channel directions; thus, wood after carbonization not only can be used as a self-supporting electrode but also has high ionic/electronic conductivity. However, carbonized wood only contributes a limited double-layer capacitance, which has little effect on the improvement of energy density .…”

Recent progress in the development of smart supercapacitors

“…Of course, the core to maintaining the normal and efficient operation of these devices lies in the development of new energies. At present, these new energies mainly include batteries 13–15 and supercapacitors 16–18 . Because of their high power density, supercapacitors can effectively meet people's pursuit of a fast‐paced life, and more researchers will pay attention to them.…”

“…At present, these new energies mainly include batteries [13][14][15] and supercapacitors. [16][17][18] Because of their high power density, supercapacitors can effectively meet people's pursuit of a fast-paced life, and more researchers will pay attention to them. However, as mentioned above, the development of human society has entered the intelligence era, which also puts forward higher requirements for energy storage devices, not just storing charges and then supplying energy when needed.…”

Three-Dimensional ZnCo-MOF Modified Graphene Sponge: Flexible Electrode Material for Symmetric Supercapacitor

“…In order to find a solution for the scarcity of fossil fuels, one of the biggest problems in the world, the search for economical and sustainable energy conversion and storage systems continues unabated. , In addition to the environmental pollution of fossil fuels, they will run out in the coming years, which is also a major problem. Therefore, it is of great importance to find an alternative, clean, and low-cost method to store energy that meets the world’s demands. − Two important candidates to help us get out of this global energy crisis are batteries and supercapacitors (SCs). − The biggest advantage of batteries compared to other storage devices is that batteries have very large volumetric energy densities and can be applied in the field of compressible electronics.…”
