A Rice University chemist found that adding asphalt to lithium batteries allowed the battery to go "from zero charge to full charge in five minutes, rather than the typical two hours or more needed with other batteries."
The Rice lab of chemist James Tour developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material’s promise for use in rapid charge and discharge devices that require high-power density. The finding is reported in the American Chemical Society journal ACS Nano.
Batteries have always been a barrier in the evolution and adoption in soft, wearable devices. You wouldn’t want the chemicals inside batteries to leak out onto your skin and ideally there wouldn’t be a big risk of them bursting into flames either. Stanford engineers have developed a new kind of solid polymer battery that can […]
This PulseTech charger, and responsible behavior, has changed my life. I used to kill the batteries in my cars and motorcycles on an almost annual basis. I would intend to ride the bike more, but it’d be rainy. I would keep telling myself to take the Vanagon out but it was parked behind my daily […]
As a method of testing battery output, it seems a bit elaborate, but racing AAs down coiled copper tubes looks like a lot of fun. Mr. Michal: Duracell, Varta or Energizer, Which Will Be the Best? In this video you’ll see two races between aa batteries. Infinite loop and DRAG RACE. How to make the […]
With all due respect to our vegetarian friends, there might be nothing more intrinsically linked to the 4th of July holiday than a big ole cookout. Sure, fireworks and celebrating the birth of a constitutional republic are great too, but showing off your cooking prowess with a brilliantly seared, mouth-watering slab of grade-A American beef […]
We’re at the midway point of 2020. So…how’s the year going for you so far? Yeah…we can guess. But while there’s a lot about 2020 we can’t directly control, maybe a little retail therapy can help make you feel better. Sure, the 39 items we gathered together can absolutely bring a smile to your face. […]
When revved-up kids used to dribble a basketball through the kitchen or practice their footwork with a soccer ball in front of the television, exasperated parents would often just send ‘em outside to play. But these days, sending kids out might not be the best course of action. Despite all the changes, many budding young […]
