Abstract
Official abstract text for this publication.
The present disclosure provides a method for manufacturing a silicon clathrate positive electrode active material capable of removing at least a portion of a type I silicon clathrate, and a method for manufacturing a lithium-ion battery comprising manufacturing such a silicon clathrate electrode active material. Disclosed methods of making silicon clathrate electrode active material, comprising the following steps: (a) providing silicon clathrate particle that contain a type I silicon clathrate and a type II silicon clathrate, and (b) contacting the silicon clathrate particle with a hydrofluoric solution to remove at least a portion of the type I silicon clathrate.
First claim
Opening claim text (preview).
1 . A method for manufacturing a silicon clathrate electrode active material, comprising the following steps: (a) providing a silicon clathrate particle containing a type I silicon clathrate and a type II silicon clathrate, and (b) contacting the silicon clathrate particle with a hydrogen fluoride solution to remove at least a portion of the type I silicon clathrate. 2 . The method according to claim 1 , wherein in the step (b), the ratio of the amount of substance of the hydrogen fluoride solution to the mass of the silicon clathrate particle is greater than 0.0060 mol/g and less than 0.2500 mol/g. 3 . The method according to claim 1 , wherein the solvent of the hydrogen fluoride solution is a mixed solvent of water and an organic solvent. 4 . The method according to claim 1 , wherein in the mixed solvent, the ratio of the mass of the water to a total mass of the water and the organic solvent is 30% by mass or greater and 90% by mass or less. 5 . The method according to claim 1 , wherein the silicon clathrate electrode active material is for a negative electrode active material of lithium-ion batteries. 6 . A method for manufacturing a lithium-ion battery, comprising the following steps: manufacturing a silicone clathrate electrode active material by the method according to claim 1 , and forming an electrode active material layer containing the silicon clathrate electrode active material.
