There is a lot of innovation happening in the battery space at the moment and, in my opinion, it couldn't come at a better time. If you think about it, while so much other technology has evolved in leaps and bounds, batteries historically have been very slow to evolve yet we are still quite dependent on them to power all of our gadgets and devices. The idea of a longer-lasting battery that can recharge so quickly is a welcome innovation in this space.
I'm confused. Although the title says that a longer-lasting battery was invented, the story says "Another weakness in the design is that the battery's lifespan isn't as long as traditional graphite-based design".
Yes, you're right, TJ...tricky wording there...It depends on what you mean as longer lasting. The battery will run out more quickly but it will continue to be charged and recharged longer, and apparently they are working on the design so it will eventually be longer lasting in both respects. Sorry for the confusion...I should have worded it more clearly.
Thanks for posting this: potentially really good news. And yes, it's helpful to use two different terms for total lifespan and length of charge. In cell phone batteries, the latter is called "talk time."
Nice story, Liz. Let's hope this technology reaches its potential. Material scientists have tried many lithium-ion chemistries over the past 20 years and short cycle life has often been a problem. Lithium-sulfur, for example, has offered high energy but has had problems getting past about 50 cycles. Most automakers are looking for a minimum of a thousand cycles. Some are looking for 2,000 because they want some margin for warranties. Let's hope these engineers can do it.
I didn't know that term, Ann, but it makes sense! Now I will know to use it when I am talking about cell phone batteries anyway and avoid any confusion in the future.
Yes, it would be great if they could overcome what you note is a long-time hurdle. This would be a great invention, particularly for the future of electric vehicles and could overcome any remaining hurdles to adoption. It's good to know at least that some very clever people are looking at the problem in new ways.
The weakness in any portable system is the battery. If you can recharge in 10 minutes, you have a winner.
And they said nothing good ever came out of California...
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
