I wrote a piece several years ago that touched on the topic of batteries being the one piece of technology that has not improved at the same rate as other parts of technology such as the microprocessor, and despite all of the advancements in lithium-ion battery technology since then, including ones I have written about recently, not much has actually changed. However, researchers at MIT’s Lincoln Laboratory and Department of Materials Science and Engineering are working to change that.  ...
While my previous article on flexible Lithium-ion batteries focused on wearables as a driving force in flexible battery development, this article is focused on a new type of flexible Lithium-ion battery technology being developed at the Georgia Institute of Technology that aims to help relieve the dependency current Lithium-ion batteries have on nickel and cobalt, two metals that are becoming more volatile in the world’s markets. I previously published an article that details why those met ...
One of the major problems plaguing wearable technology today is the lack of batteries that can safely and reliably flex with the movement of clothing without breaking and leaking harmful electrolyte, or even bursting into flames altogether. That’s not to mention how uncomfortable rigid batteries are when affixed to the clothing. Lack of a reliable flexible battery also prevents innovation in flexible electronics such as foldable smartphones, roll-up screens, etc, but that may change soon t ...
Spintronics, when combined with thermodynamics, creates an electric generator that utilizes the electron spin to harvest energy at room temperature. (Image credit: Martin Bowen)   Scientists from the CRNS, the University of Strasbourg, the University of Lorraine, and Uppsala University have discovered a way to harvest thermal energy at room temperature by combining spintronics and quantum thermodynamics. Spintronics utilizes the spin of an electron and its associated magnetic moment in soli ...
PG&E provides electric service for approximately 16-million people in northern and central California. (Image credit: PG&E)   Several days ago, California’s electric utility provider PG&E (Pacific Gas and Electric) announced it would proactively cut power during days of strong winds and extreme fire danger in an effort prevent wildfires, as it’s widely believed overhead power lines were responsible for sparking last year’s deadly Camp fire. The intentional out ...
Hunstable Electric Turbine claims the same range on smaller batteries! (Image credit: HET)   Linear Labs, a family-founded company, run by father-and-son, Fred Hunstable and Brad Hunstable, have developed “a new class of electric motor” called the Hunstable Electric Turbine (HET). The duo promises their HET will, for the same size, weight, volume, and exact amount of input energy into the motor, always deliver two to three times torque output of any electric motor in the world. ...
Researchers discovered uranium ditelluride exhibits a rare phenomenon known as re-entrant superconductivity, making it a promising material for use in quantum computers. (Image credit: University of Maryland)   Researchers from the University of Maryland, NIST (National Institute of Standards and Technology), the National MagLab (National High Magnetic Field Laboratory), and the University of Oxford have observed an unusual phenomenon known as re-entrant superconductivity in uranium ditell ...
There are two broad types of DC Power supplies: linear and switched-mode. Both designs use different techniques to achieve the same result: convert AC power to DC power. Depending on the application, each power supply type enjoys a few advantages. This article will briefly go through the difference between linear and switched-mode power supplies.   Linear power supply A large transformer (as per power needs) is used in a linear supply to reduce voltage from the AC line to a lower AC volta ...
The researchers were able to synthesize a forbidden compound of cerium and hydrogen (CeH9), which demonstrates superconductivity at low pressures. (Image credit: MIPT)   Researchers from the US, Russia, and China have seemingly done the impossible by synthesizing a ‘forbidden,’ or ‘impossible’ compound, known as cerium superhydride (CeH9), that exhibits superconductivity at low pressure. Superconductors are capable of conducting an electrical current with little to ...
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 ...
