The superior CoNi-MOF in our study exhibits advanced electrochemical energy storage performance, achieving a high specific capacity of 382 C g –1 (1 A g –1), 2.0 and 1.4 times that of Co-MOF and Ni-MOF, respectively. Such a significant enhancement results from the surface-controlled reaction kinetics and the low onset potential contributed
Despite their numerous advantages, the primary limitation of supercapacitors is their relatively lower energy density of 5–20 Wh/kg, which is about 20 to 40 times lower than that of lithium-ion batteries (100–265 Wh/Kg) [6].Significant research efforts have been directed towards improving the energy density of supercapacitors while maintaining their excellent power density, typically

A flywheel can be used to keep machinery working smoothly and mechanically store kinetic energy from the rotor mass''s fast rotation. FESS has kinetic energy that is connected to both inertia and speed. FESS can be divided into two primary categories. Low-speed flywheels are those that spin at fewer than 10,000 revolutions per minute and are more common in
Kinetic Batteries uses an advanced spray process known as cold spray to additively consolidate active materials and metal binder powders into a lithium-ion battery electrode. This approach eliminates the need for solvent drying or calendaring and can be implemented directly on existing roll-to-roll manufacturing lines or can be used to truly 3D print electrodes into any shape or
Remarkably, the energy density of the K + -S battery peaks at 1,190 Wh kg S−1, or 392 Wh kg S+Zn−1, when accounting for the masses of cathode and anode active materials, outperforming K-S organic systems and traditional aqueous batteries (Figure 2 F; Table S4).
To the best of our knowledge, the observed rate capability is superior to all K-S organic batteries and exceeds both aqueous Li + -S and Na + -S batteries (Figure 2 D; Table S3). Post 500 cycles at 5 A g −1, the battery still provides a capacity of 609 mAh g −1, with a CE consistently above 99.9% throughout the cycling (Figure 2 E).
The enhanced kinetic performance of high-energy density batteries is not only determined by the multi-electron cathodes but also influenced by the metal anodes. For metallic anodes, the metal-affinity framework can provide nucleation sites to reduce overpotential and induce homogeneous deposition .
It can be confirmed that the high-energy density of the battery directly relates to the number of electrons involved in the reaction. Meanwhile, the high working potential and light mole weight are also important to achieve outstanding energy density.
The kinetic performances of Li-S and Li-O 2 batteries are limited by the low electrical conductivities and poor wettability of electrode/electrolyte interfaces. Furthermore, the formation and fracture of Li-S and Li-O bonds show certain irreversibility caused by the low reaction activity.
In the case of the sulfur (S)-based aqueous battery (SAB), although fast kinetics can be achieved between liquid–liquid S species, the conversion reaction between solid-to-liquid S species presents slower kinetics due to extra solid-involved activation, leading to inferior rate performance 54.
