The present invention provides a nonaqueous electrolyte secondary battery, an electrode and a carbonaceous material. The nonaqueous electrolyte secondary battery has an electrode containing a carbonaceous material obtained by a production method comprising a step of heating a compound of formula (1) or a calcination product of the compound, under an inert gas atmosphere in the range of from 200° C. to 3000° C.: wherein R represents a hydrocarbon group having 1 to 12 carbon atoms, and a hydroxyl group, an alkyl group, an alkoxyl group, an aryl group, an aryloxy group, a sulfonyl group, a halogen atom, a nitro group, a thioalkyl group, a cyano group, a carboxyl group, an amino group or an amide group may be attached to the hydrocarbon group; R′ represents a hydrogen atom or a methyl group; n represents 3, 5 or 7.
A nonaqueous electrolyte secondary battery having an electrode containing a carbonaceous material obtained by a production method comprising a step of heating a compound of formula (1) or a calcination product of the compound, under an inert gas atmosphere in the range of from 200° C. to 3000° C.:
Use of a carbonaceous material obtained by a production method comprising a step of heating a compound of said formula (1) or a calcination product of the compound, under an inert gas atmosphere in the range of from 200° C. to 3000° C., for an electrode of a sodium ion secondary battery.
Use of a compound of said formula (1) or a calcination product of the compound, for producing an electrode composed of a carbonaceous material for a sodium ion secondary battery.
A carbonaceous material obtained by a production method comprising a step of heating a compound of said formula (1) or a calcination product of the compound, under an inert gas atmosphere in the range of from 1100° C. to 2700° C.
Use of a carbonaceous material obtained by a production method comprising a step of heating a compound of said formula (1) or a calcination product of the compound, under an inert gas atmosphere in the range of from 1100° C. to 2700° C., for an electrode.
A method of producing a carbonaceous material, comprising a step of heating a compound of said formula (1) or a calcination product of the compound, under an inert gas atmosphere in the range of from 1100° C. to 2700° C.
