“…Transition metal nitrides (TMNs) have arose public concern for many electrochemical reactions due to the low cost, high conductivity, thermal stability and similar electronic structure with the noble metals. [1][2][3][4] Titanium nitride (TiN), particularly, is an amazing target that possesses superior electrical conductivity (4000-55500 S cm À 1 ), excellent electrochemical and mechanical stability, has been efficiently applied in various reactions that require noble metal catalysts, including fuel cells, [5][6][7][8][9][10][11] supercapacitors, [12][13][14][15][16][17][18][19][20] dye-sensitized solar cells, [21][22][23][24][25][26][27][28] lithium ion and lithium air batteries, [29][30][31] and so on. In addition, TiN was also widely investigated as an ideal alternative catalyst support to perishable carbon support, and the resulting catalysts exhibited improved activity and durability.…”

Electrocatalysts that exhibit both, high performance and durability are essential for the promotion and commercialization of energy conversion devices. Transition metal nitrides (TMNs) hold great potential in many electrochemical catalytic processes, whereas the rational syntheses of highly open and three‐dimensional titanium nitride‐based nanostructures through a facile and efficient strategy is still a challenge. Herein, a scalable and effective method is proposed for the rational synthesis of mono‐ or bi‐metallic titanium nitride with three‐dimensional urchin‐like porous structures, which exhibit high electrochemical stability and structure durability. When being used as the support, the resultant electrocatalyst possesses much higher activity and durability in oxygen reduction reaction as well as methanol oxidation reaction. This work provides a general approach for the rational design of TMN‐based electrocatalysts or devices for application in energy conversion and storage technologies.

“…Wang reported that Si@TiN electrode materials have good cycling stability, delivering a capacity of 1900 mAh g −1 after 100 cycles at 0.1 C . Zhang demonstrated that the silicon nanorods supported by TiN nanowires can retain a capacity of 3258.8 mAh g −1 after 200 cycles at 1 A g −1 . Due to the electrochemical inactivity of TiN, the homogeneous coating of TiN on the Si particles is necessary to achieve the high‐energy density and the excellent electrochemical stability …”

Micron‐sized Si particles are successfully coated by TiN and N‐doped hard carbon (NC) via the combination of the solution method and the tape‐casting method. The double‐coated Si@TiN@NC electrode exhibits excellent electrochemical stability and rate capability, which delivers a reversible capacity of 1024 mAh g−1 at a current density of 4 A g−1 after 550 cycles, corresponding to a capacity retention of 85%. Even at 8 A g−1, the capacity still maintains 1087 mAh g−1. Further investigation shows that the electrochemical enhancement of Si@TiN@NC is mainly attributed to the buffering effect of NC, and the excellent electronic conductivity and mechanical stability of TiN. The TiN@NC double‐layer coating structure provides a new strategy for the design of high‐performance silicon anode in lithium ion batteries (LIBs). Furthermore, the tape‐casting method is a promising way to massively produce silicon‐based composites.

“…On the other hand, transition metal nitrides are well known for supercapacitors and lithium-ion battery applications. Various types of metal nitrides such as: TiN [19], VN [20], Mo 2 N [21,22], Zn 3 N 2 [23], Ni 3 N [24], NbN [25], revealed high reversible insertion and extraction of ionic species and the capability of storing lithium by the intercalation mechanism [26][27][28][29][30][31]. Our group investigated titanium nitride (TiN), as a new class of cathode materials and demonstrated its superior performance of 726 mAhg -1 after 100 cycles at 0.1 C rate [32].…”

The Lithium Sulfur (Li-S) battery system is one of the most promising candidates for electric vehicle applications due to its higher energy density when compared to conventional lithium ion batteries. However, there are some challenges facing Li−S battery commercialization, such as: low active material utilization, high self-discharge rate, and high rate of capacity fade. In this work, a series of transition metal nitrides: Tungsten nitride (WN), Molybdenum Nitride (Mo 2 N), and Vanadium Nitride (VN) was investigated as cathode materials for lithium polysulfide conversion reactions. Capacities of 697, 569, and 264 mAh g-1 were observed for WN, Mo 2 N, VN, respectively, with 8 mg cm-2 loading, after 100 cycles at a 0.1 C rate. WN higher electrochemical performance may be attributed to a strong reversible reaction between nitrides and polysulfide, which retains the sulfur species on the electrode surface, and minimizes the active material and surface area loss. X-ray photoelectron spectroscopy (XPS) analysis was performed to gain a better understanding of the mechanism underlying each metal nitride redox reactions.
