Annie Goedkoop, Director of Publications for ECS ran across this story in Phys.org.

Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times. The key material: sand. Yes, sand.

“This is the holy grail – a low cost, non-toxic, environmentally friendly way to produce high performance lithium ion battery anodes,” said Zachary Favors, a graduate student working with Cengiz and Mihri Ozkan, both engineering professors at UC Riverside.

Quick shout out to Zachary Favors, the graduate student working on this, ECS has great membership deals and benefits for students!

On June 12, Tesla announced that it would no longer initiate patent lawsuits against anyone using their technology in good faith. Tesla CEO, Elon Musk, wrote this about the removal of patents from a wall in their Palo Alto lobby, “they have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology.”

Musk went on to state,

We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform. Technology leadership is not defined by patents, which history has repeatedly shown to be small protection indeed against a determined competitor, but rather by the ability of a company to attract and motivate the world’s most talented engineers. We believe that applying the open source philosophy to our patents will strengthen rather than diminish Tesla’s position in this regard.

Bravo to Tesla! ECS shares similar values and launched author choice open access earlier this year. Some of our reasons for committing to open access closely parallel Mr. Musk’s remarks: the need to accelerate research, technology and innovation. A recent evaluation suggested that close to 65% of ECS technical content involves the sustainability of our planet. By opening access to the latest findings, ECS believes we can better support innovative research, reach new audiences, and enable faster scientific breakthroughs.

For more than 110 years the ECS mission has been to disseminate scientific information to the widest possible audience. Our vision for the future remains true to this goal, and expands upon it by creating uninhibited availability of ECS content through open access – an initiative that democratizes the science and hopefully, accelerates scientific progress.

One of the goals of this blog is to share some of the content we swap with each other in the office and with members around the world. And we are not just talking sharing information that we are publishing. It’s anything we find interesting.

Here’s a perfect case, Logan, who’s an editorial assistant here, emailed me this article from ChemistryWorld about a super stretchy battery with a video:

Lithium ion batteries that can be stretched by 600% have been unveiled by scientists in China. In the future, the fibre shaped batteries could be woven into textiles to satisfy the ever-growing requirement for wearable devices.

Huisheng Peng and colleagues at Fudan University made the superelastic batteries by winding two carbon nanotubes–lithium oxide composites yarns, which served as the positive and negative electrodes, onto an elastomer substrate and covering this with a layer of gel electrolyte. The batteries owe their stable electrochemical performance under stretching to the twisted structure of the fibre electrodes and the stretchability of the substrate and gel electrolyte, with the latter also acting as an anchor. When the batteries were stretched, the spring-like structure of the two electrodes was maintained.
