Rare earth elements (REE) are considered critical metals due to their supply risk and
growing demand in various industrial segments. Waste electrical and electronic equipment …

In this work, we leached the electrochemically active powder (black mass) from spent Ni-MH
batteries in an aqueous solution containing citric acid and hydrogen peroxide. The obtained …

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 …

The purpose of this work was to explore the incorporation of black manganese oxide powder
extracted from alkaline batteries into sintered-clay bricks. The black manganese oxide …

Electric vehicles (EVs) are becoming more popular than internal combustion engines for
reasons such as ease of use, durability, efficiency, and speed. Electric motors aim to …

The extensive use of smartphones is increasingly generating technological waste, such as
the spent lithium-ion spent batteries, which contains potentially toxic metals that may affect …

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

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 …
