Calcium ion battery chemistry with double the capacity of lithium ion now has a potential battery electrode solution. (Link is to a pdf download.) Toyohashi University of Technology (TUT) researchers have demonstrated calcium ion batteries (CIBs) using pigment based electrodes such as Prussian Blue and its analogues. The CIBs showed excellent cyclability of discharge and […]






MIT’s new approach to the design of a liquid battery uses a passive, gravity-fed arrangement similar to an old-fashioned hourglass. The concept could offer great advantages due to the system’s low cost and the simplicity of its design and operation. The MIT team of researchers has made a demonstration version of the new battery. Liquid […]






Chemists from Hiroshima University have developed organic radical batteries that are re-chargeable and continue to function at below-freezing temperatures. The Hiroshima team uses a new synthesis method to make an organic battery. The team has a step into one of the hardest problems of batteries – how to function well when cooled down. Transporting power […]






University of California, Irvine (UCI) researchers have invented a nanowire-based battery material that can be recharged hundreds of thousands of times. Scaled up and marketable the tech would get us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, […]






Pacific Northwest National Laboratory (PNNL) researchers have made an unexpected discovery leading to a rechargeable battery that’s as inexpensive as conventional car batteries, but has a much higher energy density. The new battery could become a cost-effective, environmentally friendly alternative for storing renewable energy and supporting the power grid. The team identified this energy storage […]
