This product is designed for advanced lithium-ion battery research, specifically as an uncoated silicon oxide anode material. It offers a controlled particle size distribution, with Dv(10) at 0.795 μm, Dv(50) at 4.57 μm, and Dv(90) at 9.18 μm, ensuring consistent electrochemical performance in experimental setups. As a pure silicon oxide variant without surface coating, it provides a baseline for studying the intrinsic properties of SiO anodes, including volume expansion behavior and capacity retention. Commonly used in academic and industrial R&D labs, this material enables systematic evaluation of slurry formulation, electrode fabrication, and cell assembly. Available in quantities from 20 g to 1000 g, it supports scalable testing from coin cells to pouch cells. The uncoated nature makes it particularly suitable for comparative studies against carbon-coated or modified silicon oxides.
