Silicon Anode Powders for Li-ion Battery Manufacturing

Silicon Anodes composed of silicon nano particles have shown great potential as drop-in additives to increase the efficiency and energy storage capacity of lithium-ion batteries. Until recently, the principal drawback to silicon nano particles has been surface oxide passivation, a process which increases impedance and reduces cyclability in the anode.

Targray Silicon Anode Formulations

Targray high purity silicon anodes are able to achieve exceptionally high specific capacity without a significant effect on cycle lifetime. This is made possible through an innovative nano particle manufacturing process that protects the silicon from oxide passivation. Available in powder and granular form, our surface passivated Si Powders are dispersible in battery solvents while preventing agglomeration. They are engineered to slurry seamlessly with other battery materials and produce very homogeneous and stable coatings, which makes them suitable for a number of applications including in lithium-ion batteries, photovoltaics, semi-conductors, electronics, and coatings.

Targray Silicon Anodes – Key Features

  • Homogeneity | Targray silicon anode powder is 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.
Working closely with our supply partners and organizations including the Electrochemical Society and NAATBatt International, we help lithium-ion battery manufacturers worldwide commercialize new technologies for the Battery Energy Storage market.
