a step of heating the layered silicon compound at not less than 300° C.
First claim
Opening claim text (preview).
1 . A method for producing a silicon material, the method comprising: a step of heating CaSi 2 powder in a range of 400 to 1000° C.; a step of reacting acid with the CaSi 2 powder having been subjected to the step of heating CaSi 2 powder in a range of 400 to 1000° C., to obtain a layered silicon compound; and a step of heating the layered silicon compound at not less than 300° C. 2 . The method for producing a silicon material according to claim 1 , wherein the CaSi 2 powder is produced through grinding. 3 . A method for producing a power storage device, the method comprising a step of producing a negative electrode using the silicon material produced by the production method according to claim 1 . 4 . A method for producing CaSi 2 powder having reduced distortion in crystals thereof, wherein CaSi 2 powder is heated in a range of 400 to 1000° C. 5 . CaSi 2 powder in which a mean local misorientation of CaSi 2 crystals is in a range of 0 to 0.7 degrees. 6 . (canceled) 7 . A method for producing a silicon material, the method comprising: a step of reacting acid with CaSi 2 powder having a mean local misorientation of CaSi 2 crystals in a range of 0 to 0.7 degrees, to obtain a layered silicon compound; and a step of heating the layered silicon compound at not less than 300° C. 8 . A method for producing a power storage device, the method comprising a step of producing a negative electrode using the silicon material produced by the production method according to claim 7 .
