Nano titanium nitride can be dispersed in other materials to form a conductive network due to its small particle size and large specific surface area, which greatly improves the electrical conductivity of the composite. Therefore, nano titanium nitride is a material with broad application prospects. Among them, the application of nano titanium nitride TIN in electrochemistry is as follows:
1) Application in fuel cells
1 nano TiN as electrode catalyst carrier material
As a carrier material for the electrode of a fuel cell, nano titanium nitride TiN not only improves the electrooxidation ability of the anode to organic fuel such as methanol, but also improves the electroreduction catalytic performance of the cathode for oxygen, and synergistic effect with the platinum Pt. The corrosion resistance and long-term stability of the electrode are greatly enhanced, and the performance of the fuel cell is greatly improved.
Application of nano TiN in bipolar plate materials
The metal materials generally used as the plates include Ti, Al, and stainless steel, and the disadvantage of using the metal plates is that the corrosion resistance is relatively poor, which cannot meet the long-term stability of the fuel cell. TiN has high electrical conductivity, corrosion resistance, oxidation resistance and excellent mechanical properties. It is suitable for composite modification of metals such as Ti, Al and stainless steel to improve the corrosion resistance and electrical conductivity of bipolar plates.
2) Application in super-capacitors
Various nano structured TiN with excellent electronic conductivity and high specific surface area, such as nanotube arrays, nanowires, nanorods, and core-shell structures, can improve the capacitance performance and cycle stability of super-capacitors.
3) Application in lithium ion battery
As a carrier material for lithium-ion batteries, TiN not only improves the conductivity of the electrode, but also greatly increases the diffusion coefficient of lithium ions, thereby improving the capacity, rate and stability of the battery. It is widely displayed in lithium-ion batteries. Application prospects.
