TL;DR: In this paper, a method for producing silica-coated organic particles comprises: a cracking step of cracking raw material silica particles whose volume average particle diameter of the primary particles is 200 nm or less, in such a manner that a bulk density reaches 450 g/L or less by a jet mill.
Abstract: PROBLEM TO BE SOLVED: To provide silica-coated organic particles having excellent fluidity, and to provide a method for producing the same.SOLUTION: A method for producing silica-coated organic particles comprises: a cracking step of cracking raw material silica particles whose volume average particle diameter of the primary particles is 200 nm or less, in such a manner that a bulk density reaches 450 g/L or less by a jet mill; and a mixing step of mixing the silica particles obtained in the cracking step with organic particles having a volume average particle diameter larger than that of the silica particles to stick surfaces of the organic particles. By sticking the silica particles having the above characteristics to the surfaces of the organic particles, the stuck silica particles are interposed among the organic particles to improve the fluidity characteristics of the organic particles. The silica particles having the above characteristics constitute a powder in which the primary particles are separated from each other in spite of their particle diameters in the order of nanometer.

TL;DR: In this paper, the negative electrode material for a secondary battery is graphite having a particle size of 1-100μm and a purity of 90% of more, obtained by milling flake natural graphite with a jet mill.
Abstract: PURPOSE: To provide negative electrode material for a secondary battery, especially for a lithium secondary battery having high charging/discharging capacity and efficiency. CONSTITUTION: Electrode material for a secondary battery is graphite having a particle size of 1-100μm and a purity of 90% of more, obtained by milling flake natural graphite with a jet mill. When the graphite is charged/discharged at a voltage of 0.02-0.5V, charging/discharging capacity obtained on and after a second cycle is 250mAh/g or more.
