Quartz surface sand, as a high-purity and highly wear-resistant mineral raw
material, has a wide range of potential applications. Quartz plate sand may also
play an important role in the manufacturing of electric vehicle (EV) batteries.
The following are potential application areas of quartz plate sand in the
manufacturing of electric vehicle batteries:
1. Additives for positive and negative electrode materials of batteries
The high purity characteristics of quartz plate sand make it possible to use
it as an additive in some battery materials to enhance performance. As a
high-purity silicon source, quartz's silicon dioxide (SiO ₂) can be combined
with other materials to form composite materials, improving conductivity and
stability in the positive and negative electrodes of batteries. Specific
applications include:
Silicon based negative electrode material: Silicon has a high theoretical
capacity as a negative electrode material in batteries, but its cycling
stability is poor due to the expansion effect. The silica extracted from quartz
plate sand can be combined with other materials to manufacture high-performance
silicon-based negative electrode materials, improving the capacity and cycle
life of batteries.
Improvement of battery electrolyte: Trace elements such as aluminum and iron
in quartz plate sand can be used to optimize the stability and conductivity of
battery electrolyte.
2. High temperature battery module materials
Quartz has excellent high-temperature resistance, therefore, quartz plate
sand can be used as a reinforcing material in some high-temperature components
of batteries. It can be used to manufacture components such as battery casings,
insulation materials, cooling devices, etc., ensuring that these components can
work stably in high temperature environments. Specific applications include:
Battery casing and protective materials: The battery casing needs to have
characteristics such as high temperature resistance and corrosion resistance.
The high heat resistance of quartz plate sand can be used in the manufacturing
of battery casings to ensure the safety of batteries under high temperature
conditions.
Thermal management material: Quartz material has good thermal conductivity
and can be used in battery thermal management systems to help the battery
maintain a suitable temperature during charging and discharging, avoiding
overheating.
3. Battery packaging and structural materials
Quartz board sand has good processability and hardness, and can be used as
one of the raw materials for battery packaging materials. Its main application
areas include:
Battery packaging material: Batteries need to be packaged during production
and use to prevent external environmental influences. The high strength and
corrosion resistance of quartz plate sand make it an ideal packaging material.
It can effectively prevent damage to the internal components of the battery
caused by moisture, oxygen, and other factors.
Structural support material: In the structure of battery modules or battery
packs, quartz plate sand can be used as a reinforcing material to enhance the
robustness and stability of the structure, ensuring that the battery is not
easily deformed during high-speed charging and discharging processes.
4. Supporting materials for photovoltaic materials
With the rapid development of electric vehicles, the application of solar
cells is gradually increasing, especially for in car charging systems. Quartz
board sand can play a role in photovoltaic cells, such as photovoltaic solar
panels. Quartz, as the basic raw material of photovoltaic materials, is widely
used in the manufacturing of crystalline silicon solar cells. Therefore, quartz
plate sand has potential as a raw material for the production of silicon wafers
and solar cells in vehicle mounted photovoltaic charging systems.
The high durability and corrosion resistance of quartz sand, the supporting
material for photovoltaic modules, make it promising for application in
photovoltaic panel support frames and protective films.
5. Surface treatment and polishing materials in battery production
The fine particles and wear resistance of quartz plate sand make it an
excellent surface treatment and polishing material. In the battery production
process, surface smoothness and precision have a significant impact on the
performance and lifespan of the battery. Quartz plate sand can be used as an
abrasive for battery surface treatment, improving the accuracy and quality of
battery assembly.
Polishing of battery components: During the production process of batteries,
quartz plate sand can be used to polish the surface of battery casings,
connectors, etc., removing surface defects and improving overall appearance and
functionality.
6. Catalysts and battery reaction materials
Some components in quartz plate sand, such as silicon dioxide, can react with
other catalysts or reaction materials to enhance the performance of batteries.
Although there are few practical cases of this application in electric vehicle
batteries, with the development of new battery technologies, quartz plate sand
may play a role in the following aspects:
Lithium battery reaction promoter: Some lithium battery technologies may
require the use of catalysts to accelerate the chemical reactions of the
battery, and silicon dioxide or other components in quartz plate sand may play a
role in it.
7. Important raw materials in battery recycling
With the rapid development of the electric vehicle market, battery recycling
is becoming increasingly important. Quartz plate sand may play a certain role in
the recycling process of waste batteries, especially in separating and cleaning
different metals or harmful substances during the recycling process. Through
special processing techniques, quartz sand can help effectively remove
impurities from batteries, thereby recovering higher purity materials.
The separation material in the recycling process: The high hardness and
chemical stability of quartz sand can be used for the separation of minerals and
metals in batteries during the recycling process, especially in extracting
useful elements such as lithium, cobalt, and nickel.
epilogue
Although the application of quartz plate sand in electric vehicle battery
manufacturing may still be in the exploratory stage, its excellent physical and
chemical properties make it have broad prospects for future battery
manufacturing processes. With the development of electric vehicle technology,
quartz plate sand may play an increasingly important role in improving battery
performance, optimizing production processes, and material recycling, driving
the electric vehicle industry towards a more efficient and environmentally
friendly direction.
