Abstract
The present disclosure provides a composite powder including a carbon material having pores, a first heat-impregnating material and a second heat-impregnating material.
Claims11
A composite powder comprising a carbon material having pores, a first heat-impregnating material and a second heat-impregnating material present in the pores,
- wherein the first heat-impregnating material comprises an alkali metal ion-conductive material or precursor thereof comprising one or more elements selected from lithium, boron, oxygen, phosphorus, halogen and antimony, and
- the second heat-impregnating material comprises an elemental sulfur.
A method for producing a composite powder, wherein the following steps (1) and (2) are conducted simultaneously or separately:
- step (1):
- heating a carbon material having pores, and an alkali metal ion-conductive material or a precursor thereof comprising one or more elements selected from lithium, boron, oxygen, phosphorus, halogen and antimony at a temperature equal to or higher than the melting point,
- step (2):
- heating the carbon material and an elemental sulfur at a temperature equal to or higher than the melting point of the elemental sulfur.
