Abstract

PROCESSO PARA EXTRAçãO DOS COMPOSTOS DE LìTIO PRESENTES NAS BATERIAS SECUNDáRIAS DE ìONS LìTIO, para proceder com a separação dos compostos de lítio, dito processo inicia com a extração dos mesmos dos eletrodos e separadores através da imersão em uma mistura de etanol comercial e acetona 5% na; após preferencialmente 2 horas a extração é completada, os eletrodos, separadores, contatos de níquel, e alumínio e fitas plásticas são retirados e utilizados posteriormente para reciclagem e a solução passa por uma filtração para obtenção dos compostos de lítio, que é seco e pesado; no dito filtrado, além dos compostos de lítio, tem-se a solução de álcool, acetona, resíduos do solvente, eletrólito da bateria; além disso, o filtrado obtido da filtração (álcool, acetona e resíduos do eletrólito das baterias) é destilado, obtendo álcool 96 GL que pode ser usado novamente no processo de extração dos compostos de lítio.Process for Extracting Lithium Compounds from Secondary Lithium-Ion Batteries to Separate Lithium Compounds This process begins by extracting them from the electrodes and separators by immersing them in a mixture of commercial ethanol and 5% acetone. at; preferably after 2 hours the extraction is completed, the electrodes, separators, nickel contacts, and aluminum and plastic strips are removed and used later for recycling and the solution is filtered to obtain the dry and heavy lithium compounds; said filtrate, in addition to the lithium compounds, has the solution of alcohol, acetone, solvent residues, battery electrolyte; In addition, the filtrate obtained from the filtration (alcohol, acetone and battery electrolyte residues) is distilled to 96 GL alcohol which can be used again in the extraction process of lithium compounds.
