In this paper, we propose a hydrometallurgical procedure to treat spent Ni-Cd batteries
using organic acids as leaching agents. The electrode materials of the batteries were …

Rechargeable Ni-MH batteries contain strategic metal values which are worth to be
recovered. In the present work, a preliminary sequential chemical and electrochemical …

Se propone una ruta de procesamiento hidrometalúrgico de pilas Ni-Cd gastadas,
utilizando ácidos orgánicos como principales agentes lixiviantes. Los electrodos de tales …

A hydrometallurgical recycling procedure for the recovery of a mixed rare earths sulfate and
an electrodeposited Ni-Co alloy has been described. The latter step was found to be …

A micro-recycling approach was explored to produce catalytic metallic coatings for the
hydrogen evolution reaction (HER). For this aim, discarded Ni-Cd batteries were employed …

Introducción. Al completar su vida útil, las pilas y baterías de níquel-hidruro metálico (Ni-
MH) suelen enviarse a vertederos, lo que posibilita que el Ni que contienen se torne tóxico …

Se presentan resultados de caracterización química y mineralógica de los contenidos
internos de diversos tipos de pilas y baterías gastadas del tipo Ni-MH, Ni-Cd y Li-ión. El …
