Sulfur-Based Battery Outperforms Lithium-Ion in Tests
An all-solid lithium-sulfur battery developed by an Oak Ridge National Laboratory team led by Chengdu Liang could reduce costs, increase performance, and improve safety over designs that primarily use lithium-ion chemistries. (Source: Oak Ridge National Laboratory)
Rob, as you say, this is in it's infancy. It took six years to get to this point. There are still many aspects to be researched as well. I wouldn't look for it too soon.
This is a very good illustration of the problems faced by electric vehicle manufacturers. There are lots of technologies being researched (a good thing), but not many that will be ready soon for manufacture. That is too bad in this case, since sulfur is very abundant. It is not only available as a byproduct of chemical processes, but coal fired plants produce massive amounts. This is generally hauled away and stuffed in old coal pits.
They say their all-solid lithium-sulfur battery offers four times the energy density of conventional lithium-ion technologies.
@Elizabeth, thanks for the post. Energy density four times higher menas that present smartphone's lithium-ion battery giving eight hours of use will give 32 hours if lithium-sulfur battery is used.
Then this will be a good news for gadget developers. With longer battery cycle, gadget developers will come up with more powerful gadgets, making them more power hungry. We will still struggle with eight hours battery.
Elizabeth's article gives me a lot of hope for a revolution in electrical storage. But I wonder from where the innovation comes.
Oak Ridge is a government lab. A century ago, such inventions and research did not come from the government. It came from individuals such as Edison, Tesla, The Wrights, etc. or non-government companies.
Edison and his Menlo Park group looked at thousands of materials in the search for one suitable in an electric light bulb.
The quest for better electrical storage seems like a retelling of light-bulb filaments - find the right chemistry and electrify the world.
THe current state of patent law might have something to do with this state of affairs.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
