“…In recent years, transition metal nitrides and carbides have been demonstrated as active materials for SCs due to their high electrical conductivity and reactivity . Noticeably, enhanced high‐rate capability and excellent cycling life have been achieved in these systems, as compared to the commonly researched metal oxides.…”

High‐performance electrode materials are the key to advances in the areas of energy conversion and storage (e.g., fuel cells and batteries). In this Review, recent progress in the synthesis and electrochemical application of transition metal carbides (TMCs) and nitrides (TMNs) for energy storage and conversion is summarized. Their electrochemical properties in Li‐ion and Na‐ion batteries as well as in supercapacitors, and electrocatalytic reactions (oxygen evolution and reduction reactions, and hydrogen evolution reaction) are discussed in association with their crystal structure/morphology/composition. Advantages and benefits of nanostructuring (e.g., 2D MXenes) are highlighted. Prospects of future research trends in rational design of high‐performance TMCs and TMNs electrodes are provided at the end.

“…A workaround is to restrict the upper operating potential of these films by operating at low current densities and by increasing the amount of catalyst loading, which may be achieved with the use of porous electrodes. 94 – 96 Nonetheless, it is also desirable to support higher operating current densities without resorting to physical surface area augmentation. To this end, we sought to replace Mn with another structural metal that is stable in acid at high anodic potentials.…”

AbstractThe need for miniaturization of high-speed and high-power devices to meet consumer demand for easy access and portability has placed stringent demands on the energy requirements. There is therefore a need for high-energy density lightweight energy storage systems to meet these challenging demands of portable devices. The Liion battery since its commercialization by Sony in 1990 is still the major choice of rechargeable energy source for portable consumer electronic devices such as camcorders, laptops and cellular phones. Since 1990 however, the materials systems used in Li-ion batteries have considerably matured. The area of cathodes has witnessed considerable research activity and a number of systems have been identified with potential capacities for use in high-energy systems. In the area of anodes however, graphite still appears to be the material of choice. There is therefore a need to identify alternative electrochemically active anode systems better than carbon that could be competitive with existing and advanced cathode systems of the future while at the same time meeting the challenges posed by high-energy devices.Several metals are known to react with lithium to form useful anode materials exhibiting high capacity for Li-ion battery application. However, the cycle life of these materials is generally poor since the large volume changes (≅ 300~600 %) caused by the reaction of lithium with these metals inevitably leads to decrepitation, cracking and iii Tin-based nanocomposites on the other hand, have been synthesized by pyrolyzing the precursors generated by the infiltration of organotin compounds such as tetraethyl tin into mechanically milled PS-resin. The Sn/C electrodes exhibit a promising initial discharge capacity of ~480mAh/g that lowers to a value of 460 mAh/g after 30 cycles. The nanocomposite consists of spherical nano-particles of tin (~200nm) dispersed in amorphous carbon particles determined by TEM analysis. Results of the studies so far have shown that Sn and Si-based nanocomposites appear to be quite promising anode systems for Li-ion application.iv
