Abstract
Official abstract text for this publication.
Described herein is a method for purifying black mass of a battery, comprising providing processed cathode or anode black mass, and bringing processed black mass into contact with a basic mixture, wherein the basic mixture comprises at least one alcohol and at least one alkoxide.
First claim
Opening claim text (preview).
1 . A method for purifying black mass of a battery, comprising: providing processed cathode or anode black mass; and bringing processed black mass into contact with a basic mixture; wherein the basic mixture comprises at least one alcohol and at least one alkoxide. 2 . The method of claim 1 , wherein the at least one alcohol is a C 3 -C 8 alcohol. 3 . The method of claim 1 , wherein the at least one alkoxide is an alkali metal alkoxide or a transition metal alkoxide. 4 . The method of claim 1 , wherein the at least one alkoxide is a Li-alkoxide. 5 . The method of claim 1 , wherein the basic mixture has a pH value in the range of greater than 7.5. 6 . The method of claim 1 , wherein the ratio of the at least one alcohol to the at least one alkoxide is in the range from 99:1 to 8:2. 7 . The method of claim 1 , wherein the black mass is dry black mass. 8 . The method of claim 1 , wherein the processed black mass and the basic mixture are wet-crushed together. 9 . The method of claim 1 , further comprising a mechanical separation of the black mass and the basic mixture. 10 . A method of utilizing a basic mixture comprising at least one alcohol and at least one alkoxide for purifying black mass. 11 . The method of claim 10 , wherein the basic mixture comprises at least one Li-alkoxide. 12 . The method of claim 10 , wherein the at least one alkoxide is an alkali metal alkoxide or a transition metal alkoxide. 13 . The method of claim 10 , wherein the at least one alkoxide is a Li-alkoxide. 14 . The method of claim 10 , wherein the basic mixture has a pH value in the range of greater than 7.5. 15 . The method of claim 10 , wherein the ratio of the at least one alcohol to the at least one alkoxide is in the range from 99:1 to 8:2. 16 . The method of claim 10 , wherein the black mass is dry black mass. 17 . The method of claim 10 , wherein the processed black mass and the basic mixture are wet-crushed together. 18 . The method of claim 10 , further comprising a mechanical separation of the black mass and the basic mixture. 19 . The method of claim 10 , wherein the black mass is processed cathode or anode black mass.
