I. Applications of Phenyl Silicone in the Photovoltaic Field
Phenyl silicone plays a key role in the photovoltaic industry, primarily used in the following areas:

Photovoltaic module sealing and insulation:
Phenyl silicone is used to bond photovoltaic laminates to aluminum frames, ensuring long-term module stability in outdoor high-temperature, high-humidity, and acidic environments.
It provides excellent electrical insulation during bonding and potting of junction boxes, preventing moisture permeation and affecting cell conversion efficiency.
It offers extreme temperature resistance (-70°C to 300°C), significantly improving module weather resistance and extending service life.
Technical Advantages:
Light transmittance of up to 99% helps improve module photovoltaic conversion efficiency.
Excellent UV stability and durability surpassing traditional EVA materials.
Strong chemical stability: The "Si-O" structure is more stable than the "C-C" structure of adhesive films.

Process Innovation:
Using a lamination process instead of the traditional lamination process allows for precise positioning and reduces hidden cracking in the cells. Risks
The process is reversible, facilitating rework and improving processing yield.
Glue usage per unit area is reduced by 30%, lowering packaging costs.

II. Applications of Phenyl Silicone in Lithium Batteries
Phenyl silicone is primarily used as a key material in lithium battery manufacturing:

Anode Material Binder:
Used in natural and artificial graphite electrodes, it ensures a secure bond between the active material and the current collector (copper foil), mitigates volume expansion and contraction during charge and discharge, prevents material shedding, improves electrode flexibility, and enhances structural stability.

Performance Advantages:
Excellent low-temperature flexibility ensures lithium battery performance in low-temperature environments.
Water-based dispersions are more environmentally friendly, reducing the use of organic solvents.
High and low-temperature resistance (-70°C to 200°C) makes it suitable for extreme operating environments.

Silicon-Based Anode Applications:
When used in combination with graphite, it can achieve a specific capacity of 400-650 mAh/g, significantly superior to traditional graphite anodes.
Serves as a binder for silicon-based anodes, addressing the volume expansion issue of silicon materials.
