An overview of
Nano Silicon Powder
The most promising material to be used as an electrode for the next generation of lithium-ion batteries is silicon. With a specific capacity (3600mAh/g), it’s about 10 times greater than graphite (372mAh/g). The material’s significant expansion in the loaded (lithiation state) as well as the instability of its solid electrolyte interface (SEI) make it a restricted choice. Poor mechanical stability of silicon electrodes and their chemical passivation properties make them unsuitable for battery system cycles. There has been a lot of research into these issues and many suggestions have been made to overcome them.
The lithium insertion process changes the volume of silicon so dramatically (approx. 400%) that silicon chips off of the collector. As a result, prototype lithium-silicon batteries lose most of their capacity within ten charge and discharge cycles. Lithium-ion silicon’s stability and capacity issues are the keys to the successful development of large-capacity batteries.
Anode materials made of silicon have great potential to improve the energy storage and efficiency of lithium-ion cells. The main drawback of silicon anode materials was their surface passivation via oxidation. This process increases impedance while decreasing the circularity. The high-purity silicone anode materials have a high specific capability without drastically reducing the cycle life.

What applications?
Nano Silicon Powder
In the new generation of lithium-ion cells, silicon is the most promising type of anode materials. The nano silicon anode materials can be used for aluminum shell, cylindrical, and flexible lithium-ion batteries. Silicon anode can be mixed in the solvent to prevent agglomeration. The powder can stick to other batteries and create uniform coatings. These are ideal for use in a variety of applications such as photovoltaics, lithium-ion, and electronic batteries.
