When most people think about the composition of batteries used in modern electric vehicles such as those produced by Tesla, or the batteries that keep our smartphones powered up, the word Lithium comes to mind. In fact, these batteries are so prevalent in modern life, that the word “lithium-ion” has become a household term. What most do not know, is that lithium-ion batteries are comprised of several metals, or at least the oxides of several metals including cobalt, nickel, and lithi ...
It’s often said that supercapacitors are the future of energy storage, but for that statement to become reality, supercapacitor performance needs to increase greatly, and that is just what researchers at MIT have been working on. In a newly released study, researchers from MIT and a few other institutions have developed a novel class of liquids that could revolutionize how supercapacitors perform by increasing capacity by four or five times, improve reliability, and could reduce the risk o ...
We’ve all experienced that moment of panic when our smartphone, tablet, or laptop beeps and gives us that all too familiar five-percent of power remaining warning. Most of the time, this low power warning is nothing more than a reminder that we need to connect our device to a power source to recharge its battery. The issue of battery life vs power consumption of electronic devices has plagued engineers since before the transistor radio was first invented, and those challenges have remained ...
I would like to introduce everyone to a new project I am working on. Meet The Workbench, a new web series that is designed to showcase DIY projects, EE tools and hardware, and general Maker - DIY projects. The series is being produced, and hosted by myself, and will start off as a twice per month video series, with releases increasing as it picks up momentum.   This weeks episode follows me along as I build a DIY benchtop power supply from a kit produced by Sparkfun, and a 650W PC PSU from ...
