Batteries made with sulfur could be cheaper, greener …
One such technology could be lithium-sulfur batteries: they store considerably more energy than their lithium-ion cousins – in theory as much as six times the energy for a given weight.
Separation and recovery of valuable metals from spent lithium-ion ...
Lithium ion batteries (LIBs) are widely used in the fields of portable electronics such as mobile phones and laptops. With the increasingly serious global environmental …
Lead-acid batteries and lead–carbon hybrid systems: A review
A pasted plate concept was invented by Emile Alphonse Faure in 1881 and comprised a mixture of red lead oxides, sulfuric acid, and water. The improved efficiency set …
Selective leaching of lithium from spent lithium-ion batteries …
Traditional hydrometallurgical methods for recovering spent lithium-ion batteries (LIBs) involve acid leaching to simultaneously extract all valuable metals into the leachate. …
Study on the Environmental Risk Assessment of Lead-Acid Batteries
Lead-acid batteries were consisted of electrolyte, lead and lead alloy grid, lead paste, and organics and plastics, which include lots of toxic, hazardous, flammable, explosive …
Innovation and investment are just beginning for batteries
As we bid fossil fuels farewell and turn to renewable energy resources, batteries are set to become a key ingredient of the all-electric society. In a recent spotlight series, we looked at …
Batteries made with sulfur could be cheaper, greener and hold more energy

Improvement of Li and Mn bioleaching from spent lithium-ion batteries …
Conventional spent lithium-ion battery (LIB) recycling procedures, which employ powerful acids and reducing agents, pose environmental risks. This work describes a unique …
Selective leaching of lithium from spent lithium-ion batteries …
This study offers a new approach to enriching the relevant theory for selectively recovering lithium from spent LIBs. Keywords: selective leaching; oxalic acid; sulfuric acid; spent lithium-ion …
Sulfuric acid leaching of ferronickel and preparation of precursor ...
Ferronickel with low content of other impurities, derived from electric furnace smelting of laterite nickel ore, contains iron, nickel, and cobalt components used for the production of two kinds of …
Sulfuric acid
Sulfuric acid (or sulphuric acid in British English) is a strong mineral acid with the chemical formula H 2 S O 4. It is soluble in water at all concentrations. It was once known as oil of vitriol, a term coined by the eighth-century alchemist …
Lead-acid batteries and lead–carbon hybrid systems: A review
The improved efficiency set up new technology for lead-acid batteries, reduced their formation time, and enhanced their energy density [3, 4]. Contemporary LABs, which …
