US Patent:

8246717, Aug 21, 2012
Filed:

Aug 23, 2010
Appl. No.:

12/806877
Inventors:

W. Novis Smith - Philadelphia PA, US
Scott Swoffer - New Castle DE, US
Assignee:

Toxco, Inc. - Anaheim CA
International Classification:

C22B 9/00
C01F 17/00
US Classification:

75711, 423 211, 429 70
Abstract:

The present invention provides a process of recovering ABand/or ABas well as other metals from spent nickel metal hydride batteries from a slury by a series of separation steps utilizing the screening off of larger metal particles, removal of magnetizable small metal particles from a filter and then separating ABand/or ABby passing the filtrate through a froth flotation step to separate ABand/or ABfrom lighter small particles.

Filed:

Apr 16, 2022
Appl. No.:

17/722332
Inventors:

- Philadelphia PA, US
Scott D. Swoffer - New Castle DE, US
International Classification:

H01M 10/42
H01M 10/0525
H01M 4/505
H01M 4/525
H01M 4/583
H01M 10/54
C01G 53/00
C22B 3/00
C22B 47/00
Abstract:

A process for recovering a nickel cobalt manganese hydroxide from recycled lithium-ion battery (LIB) material such as black mass, black powder, filter cake, or the like. The recycled LIB material is mixed with water and either sulfuric acid or hydrochloric acid at a pH less than 2. Cobalt, nickel, and manganese oxides from the recycled lithium-ion battery material dissolve into the acidic water with the reductive assistance of gaseous sulfur dioxide. Anode carbon is filtered from the acidic water, leaving the dissolved cobalt, nickel, and manganese oxides in a filtrate. The filtrate is mixed with aqueous sodium hydroxide at a pH greater than 8. Nickel cobalt manganese hydroxide precipitates from the filtrate. The nickel cobalt manganese hydroxide is filtered from the filtrate and dried. The filtrate may be treated ammonium fluoride or ammonium bifluoride to precipitate lithium fluoride from the filtrate. The composition ratio of nickel to cobalt to manganese in the acid filtrate may be adjusted to a desired ratio. The anode carbon is recovered and purified for reuse.
