recently did it to much acclaim, and now Daimler is doing it too – the
German automotive corporation is launching its own home/business battery
energy storage system. Developed by Daimler subsidiary Deutsche
ACCUmotive, the Mercedes-Benz energy storage unit utilizes lithium-ion
batteries to store energy generated by solar cells, wind turbines or
Wood pulp-derived nanocellulose is turning out to be pretty useful
stuff. Previously, we'd heard how it could be used in things like high-strength lightweight composites, oil-absorbing sponges and biodegradable computer chips.
Now, researchers from Sweden and the US have used the material to build
soft-bodied batteries that are more shock- and stress-resistant than
their traditional hard counterparts.
Scientists have already devised systems that allow electronic devices to
scavenge power from ambient electromagnetic energy sources such as radio waves. While the technology has generally been limited to small devices such as wireless sensors,
a research team has recently created a scavenging system that charges a
smartphone's battery, letting it last up to 30 percent longer per
charge – and the system does so using radio signals emanating from the
Although lithium-ion batteries perform far better than alkalines,
they're also relatively costly, the lithium salts used in them aren't
widely available, and they sometimes catch fire. That's why some
scientists are suggesting sodium-ion batteries as an alternative. To that end, Williams Advanced Engineering recently demonstrated that they could be used to power an electric bike.
If you're like a lot of phone junkies and replace your phone as soon as the latest thing comes along, you'll know that often the hardware in the old phone is perfectly fine, even the battery. But fancier new screens and more powerful processors mean that battery life usually remains a problem, making battery packs a popular accessory. Enlighten's Better Re lets you get some more use out of your old phone's battery, by allowing it to slot into an adjustable external battery charger for your new phone.
