Silicon Anode Powders for Battery Manufacturers
Silicon anode materials have shown great potential as drop-in additives to increase the efficiency and energy storage capacity of lithium-ion batteries. Until recently, their principal drawback has been surface oxide passivation, a process which increases impedance and reduces cyclability in the anode. Our high purity silicon anode materials achieve high specific capacity without significant affecting cycle lifetime. This is made possible through an innovative nano particle manufacturing process that protects the silicon from oxide passivation.
Silicon Anode Battery Formulations
Available in powder and granular form, our surface passivated Si anode powders are dispersible in battery solvents while preventing agglomeration. They are engineered to slurry seamlessly with other battery materials and produce homogeneous, stable coatings. As a result, they are suitable for a range of applications including in li-ion batteries, photovoltaics, semiconductors and electronics.
Silicon Anode Key Features
- Homogeneity | The si anode materials we supply are highly homogeneous with a low particle size deviation. This facilitates incorporation into the slurry, which in turn accelerates processing times.
- Purity | Our powder is manufactured to deliver the highest achievable purity levels, with low O2 and metal content.
- Consistency | A laser pyrolysis based manufacturing process ensures batch consistency, both in terms of chemical composition and particle size distribution.
- Customization | We develop custom powder formulas to meet the size, surface, and coating requirements of commercial manufacturers.
