Description
Pure anatase nano TiO2 powder Introduction:
Anatase nano titanium dioxide powder (Nano TiO2) has a large specific surface area, and has been widely used in photocatalysis, solar cells, environmental purification, catalyst carrier, lithium batteries and gas sensors. Nano TiO2 has good fast charge discharge performance and high capacity. Cyclic voltammetry studies show that there are two kinds of dynamic processes in nano-titanium dioxide, i.e. diffusion-controlled lithium-ion intercalation-detachment and pseudo-capacitance, which can release the stress during lithium intercalation and detachment and improve the cycle life. This is also a special structure of nano-titanium dioxide. Dependent. Nanometer titanium dioxide has a wide range of applications because of its good chemical stability and thermal stability.
Nanometer titanium dioxide is an excellent lithium intercalation carrier. The lithium intercalation potential is between 1.5 V and 1.6 V, forming Li0.91 titanium dioxide-B with excellent reversible cycle capacity. Interestingly, its specific capacity is superior to that of nanoparticles with the same phase diameter similar to that of nanowires.
