Silicon is the best electrode material to use for future lithium-ion batteries. Its specific capacity (3600mAh/g) is about 10x higher than graphite (372-mAh/g). The material’s significant expansion in the loaded state (lithified) (over 300%), and the instability at the solid-electrolyte interface (SEI) severely limit its use. The silicon electrode’s poor mechanical and chemical properties make it difficult to cycle. Many studies have been conducted and many proposals made in an attempt to overcome this limitation.
During lithium insertion the volume of the silicon changes so much that the silicon breaks off the collector. A prototype lithium-silicon batteries loses most of its power in less than ten charge-discharge cycle. To achieve high-capacity Li-ion batteries, it is essential to solve the problems of stability and capacity of lithium-ion silica.
Materials such as silicon anodes have great potential in improving the efficiency of lithium ion batteries and their energy storage capability. The main problem with these materials was the surface oxidation process, which increased impedance and reduced the circularity of anodes. Our high purity silicone anode materials have a high specific capacitance without affecting the cycle life. It is a global leader in the manufacturing of silicon anodes.

A method to form a silicone anode material in a rechargeable cell includes a metal matrices that contains not more 30% silicon and a dispersed silicon structure. The metallic matrix is at least partially etched in order to at minimum partially isolate the structure of silicon.
Particles consisting of a metallic alloy containing silicon and a silicon matrix dispersed throughout the metallic matrix.
By removing metal from the alloy, at least a portion of the metal matrix is etched. This results in a porous silica particle with multiple interconnected structural elements.
Applications Nano Silicon Anode Material Si Powder :
Silicon is one the most promising materials in the next generation lithium-ion anode batteries. The nano-silicon anode material is used in cylindrical batteries with aluminum shells, flexible batteries and those that have a flexible outer casing. Our silicon powder anode is dispersed easily in the battery’s solvent, preventing a caking. These powders are designed for seamless adhesion with other battery materials, resulting in a uniform and stable coating. These coatings are ideal for a wide range of applications such as lithium-ion, photovoltaics or semiconductors.
Storage Conditions of Nano Silicon Powder Si powder
The damp reunion can affect the performance of nano Si powder and its use. For this reason, nano Si must be packed in vacuum and stored in an air-tight room. Si powder is also not to be used under pressure.
Packaging and Shipping of Nanosilicon Anode Material Si powder
The packaging we use depends on the amount of nano-silica anode Si.
Nano silicon anode Si powder packing: You may choose to have 1kg/bag (5kg/bag), 25kg/barrel or your own request.
