Nano Silicon Powder
The most promising electrode material for next generation lithium-ion batteries is silicon. Its specific capacity (3600mAh/g) is more than 10 times that of graphite (372mAh/g). The material’s significant expansion (more than 300%) in the loaded state (lithiation), and the instability of its solid electrolyte interface (SEI) make it a restricted choice. Poor mechanical stability and chemical passingivation properties make silicon electrodes difficult to cycle. There has been a lot research into these issues and many suggestions for ways to overcome them.
The volume of silicon changes during lithium insertion. It is about 400%. When this happens, the silicon cracks and falls from the collector. This causes the prototype lithium silica battery to lose the majority of its capacity in a mere 10 charge-discharge cycles. Lithium-ion silicon’s stability and capacity issues are the keys to large-capacity, high-capacity batteries.
Anode materials made of silicon have great potential to improve the efficiency and energy storage capacities of lithium-ion cells. The main drawback of silicon anode materials was their surface passivation via oxidation. This is a process that increases impedance while decreasing the circularity. High-purity silicon materials are capable of achieving high specific capacity without significantly reducing cycle life.

What are the potential applications
Nano Silicon Powder
Silicon is the most promising type of anode material in next-generation lithium-ion batteries. The nano silicon anode material is used in aluminum shell, flexible, and cylindrical batteries. Our silicon anode material can be mixed in the solvent to prevent agglomeration. They stick well to other battery materials and provide uniform and stable coatings. They can be used in a variety of applications including photovoltaics, lithium-ion batteries, and electronic components.
