High Quality Nano Silicon Anode Material Si Powder CAS 7440-21-3

Because of their high theoretical specific capacity and plentiful reserves, Silicon Anode Material is the best choice for manufacturers of lithium batteries to upgrade anodes.
Particle Size: 900nm


Nano Silicon Anode Material Si Powder


With a capacity of 3600mAh/g, silicon is the best electrode material for future generation lithium-ion batteries. This specific capacity is 10x greater than that of graphite (372mAh/g). The significant expansion (over 300%) of silicon during the loaded (lithified state) as well as the instability and electrolyte interface (SEI) make its use very limited. Poor mechanical stability and chemical passivation characteristics of the silicon electrode make it difficult for the system to cyclize. There have been many proposals and studies that attempt to overcome these limitations.

A prototype lithium-silicon-batterie will lose the majority of its capacity after a lithium-ion insertion. The silicon volume changes by approximately 400% (400%). Solving the issue of stability and capacitance of lithium-ion lithium is key to high-capacity, lithium-ion lithium-ion lithium-ion cells’ success.

Anode materials made from silicon have great potential for increasing the storage efficiency and energy capacity of lithium-ion cells. The main disadvantage of silicon anode materials was their resistance to surface oxidation, which can increase impedance or reduce the circularity. The high-purity silicon anode materials we use have a high specific capability without significantly shortening their cycle life. Wgraj is trusted globally

Nano Silicon Anode Material Si Powder


The method of forming a silicon-anode material in a rechargeable lithium battery uses a metal matrix that contains no more than 30% silicon. This includes the silicon structure. At least partly, the metal matrix is etched to isolate the silicon structure.

Metal silicon alloy particles that contain a metal matrix with a silica structure and dispersed within the metallic matrix which contains not more then 30wt% silicon.

To remove the metallic elements from the steel-silicon-alloy, the matrix is partially etched to create a porous silicon particle with a variety of interconnected structural elements.


Nano Silicon Anode Material Si Powder


Silicon is the promising material for next-generation lithium-ion anode materials. For aluminum shell batteries, nanosilicon is used as anode material in flexible, cylindrical, and flexible forms. Our silicon anode can be mixed in the liquid battery to avoid caking. The powder can blend seamlessly with other batteries and create a consistent, solid coating. These are ideal for many applications such as photovoltaics, lithium-ion, and semiconductors.

Conditions for Storage of Nano Silicon Anode Materials Si Powder

A damp reunion can affect the performance of nano Si powder and its use. Nano Si must be kept in vacuum packed and in a dry area. Si powder should not be exposed to stress.
