Tesla's Powerwall battery energy storage system for the home

The Tesla home battery system hinted at by CEO Elon Musk several months ago has finally been unveiled by Musk himself at the company’s design studio in Hawthorne, California. Dubbed the Powerwall, the stationary home battery offers 10 kWh of storage capacity for the relatively modest price of US$3,500. A smaller unit is also available at 7 kWh for $3,000, and homeowners can stack multiple units if needed.  Read More

Scientists at UCLA's California NanoSystems Institute have developed a new device that combines the high energy densities of batteries and the quick charge and discharge rates of supercapacitors. The hybrid supercapacitor is reportedly six times as energy-dense as a commercially available supercapacitor and packs nearly as much energy per unit volume as a lead-acid battery.  Read More

Researchers at Stanford University have created a fast-charging and long-lasting rechargeable battery that is inexpensive to produce, and which they claim could replace many of the lithium-ion and alkaline batteries powering our gadgets today. The prototype aluminum-ion battery is also safer, not bursting into flames as some of its lithium-ion brethren are wont to do.  Read More

Packing peanuts may be good for more than just ... packing  (Photo: Shutterstock)

When a new lab was recently being set up at Purdue University in Indiana, a lot of the equipment arrived in boxes full of protective packing "peanuts." Unfortunately, few facilities exist for recycling the little pieces of foam, so they typically end up sitting in (or getting blown around) landfills for several decades. A team of Purdue researchers, however, discovered that they could find use in better-performing lithium-ion batteries.  Read More

If you're as fascinated as we are with electric motorcycles, Richard Hatfield is a pretty special individual to sit down with. He's the founder and CEO of Lightning Motorcycles, and the man behind the world's fastest production motorcycle, the Lightning LS-218. Riding the Lightning bike was amazing and terrifying – check out our full review here. We don't usually post entire interview videos online, but this one's a beauty. Hatfield speaks at length about the LS-218, the electric vehicle business, the state of battery technology and more.  Read More

PiJuice provides the Raspberry Pi with battery and solar power options

Over the three years since its original launch, we’ve seen the small but mighty Raspberry Pi put to use in numerous projects. From phones to touchscreen desktop PCs, the little board has been at the center of all manner of creations, and with the recent release of the second generation Model B, we’re sure to see it put to use even more imaginative ways. PiJuice aims to up the versatility of the system, adding battery power to make it more portable.  Read More

PNNL's high performance zinc-polyiodide flow battery approaches the performance of some li...

A new redox flow battery developed at the Pacific Northwest National Laboratory (PNNL) more than doubles the amount of energy that this type of cell can pack in a given volume, approaching the numbers of lithium-ion batteries. If the device reaches mass production, it could find use in fast-charging transportation, portable electronics and grid storage.  Read More

Tesla home battery, which is currently produced for SolarCity's home energy storage system...

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle.  Read More

Researchers at the University of California, Riverside say they have found a way around th...

Researchers at the University of California, Riverside (UCR) have developed a silicon anode for lithium-ion batteries that outperforms current materials and gets around previous issues that would cause the battery to be inefficient and quickly degrade (or even fail catastrophically) with use. As the researchers focus on scaling up production, the advance could pave the way for higher-performance electric vehicles, electronics and all-around portable power.  Read More

The way snails control the growth of their shells has provided inspiration for a new appro...

In an ongoing effort to improve the performance of lithium-ion batteries, scientists have looked to the techniques that snails use to control the growth of their shells. This biological inspiration, combined with a peptide found to bind very effectively with materials used to make cathodes, has potential for making lighter and longer-lasting batteries.  Read More
