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.
When you pay 1,000 bucks for a thing, it’d be nice if it, you know, does what it’s supposed to. In the case of a smartphone, that means taking calls, accessing the Internet, taking great photos, downloading apps–the usual. Arguably, none of these abilities baked into our pocket computers is as important as its being […]
I am proud of me. My heart rate tracker, and my cadence sensor, both need their CR2032 batteries replaced from actual USE!
I put a new battery in my 2011 11″ MacBook Air. I love the laptop more than I minded the frustration. It will probably be easier for you. I come from the time where we carried spare laptop batteries with us, and they were instantly swappable. I’d press a small button on the battery to […]
