“…When Si atoms are inserted into the lattice of the transition metal, the d-electron bonding strength of the atoms becomes weaker, and the coupling between the energy state of Si and the metal orbital makes the electronic structure and geometric structure of the metal silicide diversified, thus having different due to the special physical and chemical properties of metals, such as high melting point, low resistivity, good heat transfer and excellent high temperature resistance, oxidation resistance, and corrosion resistance, it has been widely used in electric heating elements, integrated circuits and high temperature anti-oxidation coating and other fields. In addition, the transition metal silicides possess excellent interface properties with silicon and obtain low internal resistance because they are binder-free electrode materials (Ramly et al, 2018). It is worth noting that in addition to the above advantages, transition metal silicides also show intentional electrochemical properties, such as high theoretical energy FIGURE 5 | A brief timeline of the developments of promising of MSCs (In et al, 2008;Balcı et al, 2021;Yang et al, 2021a).…”

The Ni/Si reactive multilayer (RML) is full of application potentials including reactive joining, igniters, and power sources. Here, the Ni/Si RMLs with atomic ratios of Ni and Si (2:1, 1:1, and 1:2) are studied, where the bilayer thickness and the total thickness are controlled to be 53 nm and 2 μm, respectively. After laser ignition, a rapid explosive reaction is observed where there are two self‐propagation wavefronts and their velocities reach 7.20 and 11.93 m s−1. The uniform, small grains, and single‐phase Ni silicides are obtained and controlled by tuning growth parameters. From the understanding of the Gibbs free energy diagram, the first wavefront comes from the solid‐state amorphization reaction between the Ni and a‐Si. The formation of the final Ni silicide causes the second wavefront. The entire reaction is described by a transient heat transfer model. It proposes a key parameter called heat loss rate, which explains the importance of RML thickness and the thermal diffusivity of the substrate. It allows to accurately control the reaction rate, which masters the final silicide phase. Thus, the oxidation of samples downgrades the reliability as the self‐propagation velocity of the two wavefronts dropped to 1.34 and 1.91 m s−1 in samples after 200 h of oxidation.

“…Supercapacitors (SCs) are power devices that can be charged and discharged within seconds or minutes and a new type of energy storage device. In fact, electrode materials are the core of supercapacitors, on which the breakthrough of the supercapacitor is largely dependent. − Super large surface area and high electrical conductivity with low internal resistance during application of electrode materials are vital to contribute excellent storage performance in advanced supercapacitors. It is known that carbon-based electrodes are important for electric double-layer supercapacitors.…”

Improving the properties of activated carbon (AC) electrodes for enhancing the electrochemical performance of commercial supercapacitors is still a great challenge. In this work, a coconut shell carbonized raw material is used to successfully manufacture AC by the traditional steam activation method followed by further calcination in CO2. Results showed that a skeleton mesh wall was formed in AC, the thickness of the mesh wall was around 1.5 nm, and the crystalline phase of grain size of 1.13 nm was controlled to form independently in the wall of AC after calcination in CO2 for 4 h. The carbocyclic layer space of the grain phase ranges from 0.381 to 0.392 nm in AC, which is 17% wider than that of 0.335 nm of graphite. The AC shows a high specific surface area (1782 m2/g), and the supercapacitor prepared by AC shows a high specific capacitance (112.5 F·g–1 at 0.1 A·g–1), a high capacitance retention rate (retains 89.06% after 10,000 charge/discharge cycles), a high rate performance (specific capacitance going down from 111.2 to 65.1 F·g–1 under current density from 0.1 to 10 A·g–1), low internal resistance, and a power and energy capacity (energy density, 28.83 W h·kg–1; power density, 9.89 kW·kg–1). It is worth comparing with the typical commercial YP-50 of Kuraray, Japan.
