Anatase
nano-titanium dioxide has a large specific surface area and is widely used in
photocatalysis, solar cells, environmental purification, catalyst carriers,
lithium batteries and gas sensors.
Nano
titanium dioxide has good fast charge and discharge performance and high
capacity. Cyclic voltammetry studies show that lithium ions have two kinetic
processes in nano-titanium dioxide, namely diffusion-controlled lithium ion
intercalation-extraction of domestic and tantalum kinetics, better release of
lithium insertion and deintercalation. The stress in the cycle increases the
cycle life, which is also related to the special structure of the nano titanium
dioxide. Due to its good chemical and thermal stability, nano-titanium dioxide
has a wider range of applications.

Application
features:
1.
It can be effectively mixed into lithium cobaltate, lithium manganate, lithium
iron phosphate, and the ternary material, the addition amount is generally
0.2-0.4%.
2.
Since the dye sensitizer used can be saturated at a very low light energy.
3.
The utilization efficiency of light is high, and it is not sensitive to the
incident angle of light.
4.
Not sensitive to light shadows.
5.
It can work normally over a wide temperature range.
6.
Has a high light conversion rate.
