Because of their high theoretical specificity, Silicon Anode Material is the best choice for manufacturers of lithium batteries and companies that make anodes. Particle Size: 900nm About 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 the material when loaded (lithified) makes it difficult to use. Also, the unstable solid electrolyte interface (SEI), limits its potential. 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. Lithium insertion causes so much volume change (400%) in silicon that it breaks off the collector. A prototype lithium-silicon lithium-ion battery loses most of its capacity after only 10 charge-discharge cycles. 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 to increase the storage efficiency and energy capacity of lithium-ion cells. The main issue with silicon anode materials was their resistance to surface oxidation, which increases impedance while reducing the circularity. TRUNNANO’s high-purity silicon anode materials have a very high specific ability without dramatically reducing the cycle life. Send an inquiry for the latest Silicon Anaode Material anytime.

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 silica particle that includes a number of interconnected structural elements. Silicon Anode Material Si Pulch – Silicon is the promising material for next-generation lithium-ion anode materials. For aluminum shell batteries, nanosilicon is used as anode materials 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 or lithium-ion cells. Storage condition of Nano Silicon anode Material Si Pulp : 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. Packing & Shipping of Nano Silicon Anode Material Si Powder : Many types of packing exist, which are dependent on the amount of nanosilicone Si powder. Packing of Nano Silicon Anode Si Powder: 1kg/bag, 5kg/bag and 25kg/barrel. Or as requested. Shipping Nanosilicon anode Si Powder: can be shipped by sea, air or express, once the payment has been received.
