Electrostatic Stabilization and Characterization of Fine Ground Silicon Particles in Ethanol

Stirred media milling is a common method for the efficient production of nanoparticles. Here the grinding of semi-metallic silicon nanoparticles is presented, which are of special interest as anode material for next generation lithium-ion batteries. Ground silicon particles show an enormous reactivity in water due to particle etching but only surficial oxidization in alcoholic solvents, which inhibits further particle etching. Therefore, the...
