Product Details
Nano silica
Product IntroductionThis product is mainly prepared by applying advanced nanotechnology to surface treat nano silica based on the characteristics of batteries. The product is characterized by high content, uniform particle size, and excellent activity. Adding a certain proportion of nano silicon dioxide (CY-SP15D) to the battery can greatly improve the electrochemical performance of the battery, such as mechanical performance, conductivity, elongation at break, cycling performance, lifespan, etc. Therefore, nano silicon dioxide has high application value in the battery field.

Application characteristics:
1. The colloidal electrolyte prepared with nanometer silicon dioxide has strong gel capacity, suitable viscosity, soft colloidal electrolyte, good Thixotropy, moderate three-dimensional network structure of colloid, low resistance, large discharge current, high capacitance, no hydration stratification, and can greatly increase the cycle life of colloid.
2. Adding nano silica to the separator can increase the pore size and the total amount of colloidal electrolyte. Prevent electrolyte stratification, reduce corrosion rate, and improve service life. Adding nano SiO2 can improve the tensile strength of the separator and reduce its pore size; When the pressure on the diaphragm is greater than 30kPa, the liquid absorption amount of the diaphragm added with nano SiO2 exceeds that of the pure Glass wool diaphragm;
3The secondary lithium battery separator made by adding nano silica to the composite polymer has high liquid absorption, conductivity, and toughness. The electrolyte absorption rate reaches 184.4%, the room temperature conductivity is 1.20mS/cm, and the elongation at break is as high as 163%. The secondary lithium battery assembled using a composite polymer membrane containing nano silica has a first discharge specific capacity of 834.8mAh/g, a 40th discharge specific capacity of 400mAh/g, and a cycle efficiency of over 99.8%, demonstrating good electrochemical performance.
4. Nano SiO2 can reduce the crystallization rate of polymer systems and maintain them in an amorphous state for a longer period of time.
5. The granular nano silica between the positive and negative electrode plates can maintain the consistency of the electrolyte in the battery and significantly reduce dry water faults by passing through oxygen holes.
6. Introducing nano SiO2 through in-situ composite method is beneficial for improving the conductivity of P (VDF-HFP) based microporous polymer electrolytes.
7. Nano silica particles can absorb water from liquid electrolytes, reducing interfacial reactions.
8. By adding nano silica powder to polymer lithium batteries, the microstructure, mechanical and electrical properties of the electrolyte membrane can be greatly improved, resulting in good conductivity and mechanical strength of the electrolyte membrane.
