Method of producing silicon oxide, negative electrode active material for lithium ion secondary battery and lithium ion secondary battery using the same

A method for producing a silicon oxide including the steps of supplying silicon atoms onto a substrate through an oxygen atmosphere to form a silicon oxide layer on the substrate, and separating the silicon oxide layer from the substrate and pulverizing the separated silicon oxide layer to obtain si...

Beschreibung
Zusammenfassung:	A method for producing a silicon oxide including the steps of supplying silicon atoms onto a substrate through an oxygen atmosphere to form a silicon oxide layer on the substrate, and separating the silicon oxide layer from the substrate and pulverizing the separated silicon oxide layer to obtain silicon oxide containing silicon and oxygen in predetermined proportions, and a negative electrode active material obtained by the production method.
