Battery Manufactory

Rechargeable lithium ion batteries power our phones and tablets they drive us from A to B in electric vehicles, and have many applications besides. Unfortunately, the devices that they power can fail and the batteries themselves are commonly only usable for two to three years. As such, there are millions batteries that must be recycled. Research published in the International Journal of Energy Technology and Policy describes a new way to extract the lithium and the cobalt that make up the bulk of the metal components of these batteries. According to Ataur Rahman of the Department of Mechanical Engineering, at the International Islamic University Malaysia and colleague in the Department of Economics, Rafia Afroz, explain that the price of both lithium and cobalt is rising as demand for lithium ion batteries which require both metals for their construction are increasingly in demand. They have investigated a recycling technology that can extract with reasonable ef

Developers from Bosch and scientists at the Technical University of Munich (TUM) are using neutrons to analyze the filling of lithium ion batteries for hybrid cars with electrolytes. Their experiments show that electrodes are wetted twice as fast in a vacuum as under normal pressure. The fact that neutrons are hardly absorbed by the metal housing makes them ideal for battery research. Utilizing the neutron imaging and tomography facility ANTARES of the research neutron source FRM II, developers from Bosch and scientists at the Technical University of Munich (TUM) now used neutrons to analyze the filling process of lithium ion batteries with electrolytes. One of the most critical and time-consuming processes in battery production is the filling of lithium cells with electrolyte fluid following the placement the of electrodes in a battery cell. While the actual filling process takes only a few seconds, battery manufacturers often wait several hours to ensure the li

Lithium and cobalt are fundamental components of present lithium-ion batteries. Analysis by researchers at the Helmholtz Institute Ulm (HIU) of the Karlsruhe Institute of Technology (KIT) shows that the availability of both elements could become seriously critical. Cobalt-free battery technologies, including post-lithium technologies based on non-critical elements such as sodium, but also magnesium, zinc, calcium and aluminium, represent possibilities to avoid this criticality in the long term. These results are presented in Nature Reviews Materials. Besides lithium as charge carrier, cobalt is a fundamental component of the cathode in present lithium-ion batteries (LIBs), determining the high energy and power density as well as the long lifetime. However, as outlined in the article by Dr. Christoph Vaalma et al., this element is suffering from scarcity and toxicity issues. "In general, the rapidly growing market penetration of LIBs for electromobility applica

Researchers from RMIT University in Melbourne, Australia have demonstrated for the first time a working rechargeable "proton battery" that could re-wire how we power our homes, vehicles and devices. The rechargeable battery is environmentally friendly, and has the potential, with further development, to store more energy than currently-available lithium ion batteries. Potential applications for the proton battery include household storage of electricity from solar photovoltaic panels, as done currently by the Tesla 'Power wall' using lithium ion batteries. With some modifications and scaling up, proton battery technology may also be used for medium-scale storage on electricity grids -- -- like the giant lithium battery in South Australia -- as well as powering electric vehicles. The working prototype proton battery uses a carbon electrode as a hydrogen store, coupled with a reversible fuel cell to produce electricity. It's the carbo

A collaborative team of researchers from Shinshu University in Japan have found a new way to curb some of the potential dangers posed by lithium ion batteries. The team, led by Susumu Arai, a professor of the department of materials chemistry and head of Division for Application of Carbon Materials at the Institute of Carbon Science and Technology at Shinshu University, published their results recently in Physical Chemistry Chemical Physics. These batteries, typically used in electric vehicles and smart grids, could help society realize a low-carbon future, according the authors. The problem is that while lithium could theoretically conduct electricity at high capacity, lithium also results in what is known as thermal runaway during the charge and discharge cycle. "Lithium metal is inherently unsuitable for use in rechargeable batteries due to posing certain safety risks," said Arai. "Repeated lithium deposition/dissolution during charge/discha
