High-surface-area titanium nitride nanosheets as zinc anode coating for dendrite-free rechargeable aqueous batteries

Abstract

Aqueous zinc-ion batteries (AZIBs) have become attractive energy storage devices, owing to their high energy density, low cost, and environmental friendliness. However, the stability of the zinc-metal anode has been retarded by dendrites and side reactions during the cycling process, limiting its practical application in secondary batteries. In this work, porous titanium nitride (TiN) nanosheets with a high surface area are demonstrated as a multiplefunction anode coating to realize long-term dendrite-free AZIBs. The TiN nanosheets with the features of high specific surface area and metallic properties optimize electron conduction and zinc-ion flux, lowering the polarization on the electrode surface. In this way, the TiN-coated zinc electrodes exhibit a long cycle performance for more than 600 h without any dendrite formation. In addition, the full AZIB assembly based on the TiN-coated zinc electrode has a stable cycling performance for over 600 cycles with 97.04% capacity retention. This work expands applications of the inorganic porous materials as protective layers in high-energy battery systems.

Mechanical Reinforcement of ABS with Optimized Nano Titanium Nitride Content for Material Extrusion 3D Printing

“…Titanium Nitride (TiN)-based coatings have been applied to metallic parts of components, machining, and cutting tools to improve their wear resistance and lifetime [ 57 , 58 ]. Polycrystalline TiN thin films have also been used as diffusion barrier layers in IC technology [ 59 ], and TiN nanosheets have been coated on zinc electrodes to improve the cycle performance of high-energy rechargeable batteries [ 60 ]. Moreover, TiN has been investigated for medical applications as an abrasion- and corrosion-resistant coating on dental implants [ 61 , 62 ], while TiN-coated orthopedic implants have demonstrated effective biocompatibility and tribological properties [ 63 ].…”

Novel semiconductor materials for advanced supercapacitors

“…It exhibited excellent cycle stability, and had a larger area capacitance than a carbon-based electrode. 133 The direct production of sputter-deposited TiN films on flat silicon substrates as micro-supercapacitor electrodes without CNT templates added flexibility to the design of MSCs for practical applications. It also maintained performance attributes comparable to TiN/CNT electrodes due to the simplicity of the process and device structure, and the complementarity of EDLCs.…”

A Review on Covalent Organic Frameworks as Artificial Interface Layers for Li and Zn Metal Anodes in Rechargeable Batteries

“…[47] But they are usually very fragile, and there are some challenges to processing them into inorganic artificial SEI with dozens of microns thickness as a protective film. Using TiN nanosheets with high specific surface area and metal properties as a zinc anode protective layer optimized the electron conduction and Zn 2+ flux and reduced the polarization of the electrode surface by Jiao et al [48] The AZIB based on the TiNcoated Zn electrode had a cycle performance with more than 600 cycles and a capacity retention rate of 97.04%. MOFs have been widely used in various metal batteries and other energy storage devices due to their controllable topological structure, large specific surface area, and high thermal stability.…”
