Researchers from the Technion and the Forschungszentrum Jülich research institution in Germany have successfully tested a novel titanium-air battery. The novel battery could theoretically store up to three times more energy than standard zinc-air batteries, and since titanium is the ninth most frequently occurring material in the Earth’s crust, there are plenty of resources available to use in their creation. The team tested the battery’s abilities by applying a liquid consisting of salt with a low melting point, known as ionic liquid (EMIm(HF)2.3F). Its theoretically achievable voltage is in a similar range to that of zinc-air batteries, with an average…

With an eye toward sustainable solutions to the global energy challenge, a Technion research team has created a proof-of-concept for a rechargeable silicon (Si) battery. Rechargeable batteries are particularly necessary for the electric vehicle (EV) industry, which currently relies on Lithium-ion batteries (LIBs). LIBs, however, are expected to strain lithium (Li) production soon as well as deflect Li from more common uses such as portable consumer electronics. Until now, no battery technology has been strong enough to compete with LIBs. The novel battery allows for Si to be reversibly discharged and charged, making it a green source that could pave…
