Scientists use Silly Putty ingredient to improve batteries

By - May 16, 2014
If you see a group of scientists playing with a blob of Silly Putty, they might not be goofing off, they may be working on a technological breakthrough. That turned out to be the case with researchers at the University of California, Riverside Bourns College of Engineering , who have developed a way to use an ingredient in Silly Putty to improve lithium-ion battery life between charges by three times the industry standard.

Dual-functioning electrolyte improves capacity of long-life batteries

By - May 4, 2014 2 Pictures
The three main components of a battery's makeup: the anode, cathode and the ion-conducting electrolyte, have been long understood to serve separate, independent functions. A team of researchers at the US Department of Energy's Oak Ridge National Laboratory (ORNL) is seeking to challenge this theory, experimenting with a dual functioning electrolyte that supplements the cathode to significantly improve the capacity and longevity of long-life batteries.

Panasonic's Power Supply Container: A solar power plant in a box

By - March 25, 2014 5 Pictures
In an effort to bring reliable electricity supplies to emerging regions and remote island communities, Panasonic has developed an expandable, portable, self-contained photovoltaic system. The "Power Supply Container" comes equipped with 12 of Panasonic's HIT240 solar modules on the roof and generates approximately 3 kW of electricity, with 24 lead-acid batteries capable of storing 17.2 kWh of energy used to store excess electricity.

The story of the RYNO electric microcycle – in the inventor's own words

Six years ago, Chris Hoffmann's 13-year-old daughter Lauren said, “Daddy, I’ve been thinking about this one-wheeled motorcycle I saw in a video game. Could you actually build something like that?” What happened next changed his life. In the next few months, Chris' new company begins shipping the Ryno, a self-balancing, one-wheeled US$5250 personal mobility device that has caused tidal waves of interest across the globe. This is Chris Hoffmann’s story of what happened in the intervening six years, in his own words, and that's 20-year-old Lauren with daddy's one-wheeled motorcycle. Read More

Hybrid anode quadruples the lifespan of lithium-sulfur batteries

By - February 20, 2014
Increasing the range of electric vehicles and improving the storage of renewable energy systems are two examples of the benefits offered by lithium-sulfur batteries. Though they can hold four times the energy per mass of the lithium-ion batteries used today, their considerably shorter lifespan has proven something of a roadblock. Researchers from the Pacific Northwest National Laboratory (PNNL) have now designed a lithium-sulfur battery with four times the longevity, bringing the technology that little bit closer to maturity.

Tiny fish-tracking "jellyroll" batteries should help protect salmon

By - February 19, 2014 4 Pictures
In order to better understand and protect wild stocks of salmon, it's necessary to track their whereabouts using implanted acoustic tags. Needless to say, the longer that those tags are able to transmit a signal, the greater the amount of data that can be gathered. Scientists at Washington state's Pacific Northwest National Laboratory (PNNL) are helping make that happen, by developing batteries that have both a smaller size and higher energy density than conventional fish tag batteries.
