The effective conversion from fossil fuel-based to renewable energy sources requires cost-efficient, high-capacity, rechargeable batteries. Zinc-air batteries (ZAB) can theoretically store large amounts of energy, but current technologies require the use of expensive noble metal catalysts, or agents that speed a chemical reaction, that underperform in charging and discharging reactions. https://phys.org/news/2024-06-catalyst-commercial-high-efficiency-zinc.html Nanomaterials Mon, 03 Jun 2024 16:54:03 EDT news636652441 Remote villages in Africa and Asia are receiving electricity using a little-known type of technology: zinc-air batteries. https://phys.org/news/2018-09-zinc-air-batteries-power-remote-areas.html Energy & Green Tech Wed, 26 Sep 2018 09:43:57 EDT news457173825 It was another great year for science, particularly physics, as evidenced by a study conducted by U.K., Canadian and Italian researchers who revealed substantial evidence of a holographic universe. They published what is believed to be the first observational evidence showing that the universe could, in fact, be nothing more than a vast and complex hologram. They came to this conclusion after investigating irregularities in the cosmic microwave background. https://phys.org/news/2017-12-yearthe-articles.html Other Tue, 19 Dec 2017 08:30:01 EST news432889944 A zinc-based battery that delivers a high voltage and substantial energy capacity could be set to rival conventional lithium-ion batteries, A*STAR researchers have found. https://phys.org/news/2017-07-low-cost-battery-hefty-voltage-sustained.html Nanophysics Wed, 26 Jul 2017 07:50:02 EDT news420273832 Researchers from Case Western Reserve University and the University of North Texas have made what they believe is the first metal-free bifunctional electrocatalyst that performs as well or better than most metal and metal oxide electrodes in zinc-air batteries. https://phys.org/news/2015-04-metal-free-catalyst-rechargeable-zinc-air-batteries.html Nanophysics Mon, 06 Apr 2015 11:33:30 EDT news347538795 Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts. The results, published in the May 7 online edition of the journal Nature Communications, could lead to the development of a low-cost alternative to conventional lithium-ion batteries widely used today. https://phys.org/news/2013-05-high-efficiency-zinc-air-battery.html Energy & Green Tech Wed, 29 May 2013 15:05:06 EDT news289058696 (PhysOrg.com) -- Tall order in energy storage: Find the right technology that delivers the holy grail of the grid, a viable solution for energy storage (tough). A startup from Easton, Pennsylvania claims it’s on the fastest path. Eos Energy Storage has a formula for zinc-air batteries that it thinks can eventually be the dominant technology for use in the grid. https://phys.org/news/2012-01-eos-zinc-battery-recipe-energy.html Energy & Green Tech Wed, 04 Jan 2012 12:30:33 EST news244902606 (PhysOrg.com) -- A new breed of rechargeable zinc-air batteries is soon to be available, and may replace lithium-ion batteries in cell phones, laptops and other consumer items. Lithium-ion batteries store only a third of the energy and cost around twice as much as the new batteries. https://phys.org/news/2009-10-rechargeable-zinc-air-batteries.html Energy & Green Tech Thu, 29 Oct 2009 11:21:57 EDT news176034001
