Abstract
Se da a conocer un método de purificación y reconstrucción de la red de grafito de una batería, que incluye las siguientes etapas: someter una batería usada a descarga, ruptura por desbaste, pirólisis, ruptura fina y clasificación, secuencialmente, para obtener polvo de material de electrodo; mezclar el polvo de material de electrodo con un extractor de metales, dejar reposar, luego lavar con un agente purificador A, filtrar para obtener un residuo de filtrado A, mezclar el residuo de filtrado A con el extractor de metales, dejar reposar, luego lavar con un agente purificador B, y filtrar para obtener un grafito en bruto; someter el grafito en bruto al tratamiento des-orgánico, al enfriamiento, a la molienda de bolas y a la sustitución de la ventilación para obtener un grafito primario purificado; e introducir un gas raro en el grafito primario purificado para reparar la red de grafito.
