Sulfur Makes Safer, More Efficient Batteries

Sulfur continues to offer promise in the energy storage realm. Low- cost lithium sulfur batteries were just a research topic a few years ago, and are now moving closer to practicality with new developments that could offer four times the energy storage of lithium-ion batteries.

Researchers at Oak Ridge National Laboratory have developed a technique that uses a solid electrolyte to produce a stable, low-cost, sulfur-based battery. "The new ionically-conductive cathode enabled the ORNL battery to viagra jelly uk maintain a capacity of 1200 milliamp-hours (mAh) per gram after 300 charge-discharge cycles at 60 degrees Celsius. For comparison, a traditional lithium-ion battery cathode has an average capacity between 140-170 mAh/g. Because lithium-sulfur batteries deliver about half the voltage of lithium-ion versions, this eight-fold increase in capacity demonstrated in the ORNL battery cathode translates into four times the gravimetric energy density of lithium-ion technologies."

Sulfur is a plentiful element, and is often a waste product of industrial processes, making it very cheap and cialis health store readily available. Sulfur based batteries are also said to be less prone to instability and accidental fire than present lithium ion batteries are in part because the canada online pharmacy propecia electrolytes are solid rather than liquid.

Sulfur has been part of i recommend cialis canadian large-scale sodium sulfur batteries for many years, but that technology requires high temperatures, and is best suited for industrial applications. The new developments offer the possibility of bringing sulfur-based batteries to consumer level applications.

Susan why are you talking about molten sulfur? *Pure* Sulfur melts at 115.21 °C. Litium melts at 180.54 °C.

I can only see a temperature reference of 60°C in the article. I'm pretty sure motor oil is around those temperatures, if not higher, most of the time in your current car.

Yeah, if you bother reading the article (Susan), this is referring to a SOLID battery, not molten sulfur. Not high-temp sodium sulfur batteries. Even if it broke open, no acid would come out (no liquid electrolyte). Very nice for battery tech!

This is interesting to read about sulfur in the realm of energy storage. Energy storage now comes in various forms – batteries and now energy power bank. Over time, it has seen so many developments and new technologies that render such energy storage to woman and cialis more and more powerful and efficient. I think that in the future, we are able to storage solar energy for a longer period of time and viagra best buy would be able to power our homes.

I guess it is about time to discover more natural resources that have a few times more storage capacity to accommodate the increasing demand. Just one unit of only best offers canadian cialis for sale sulfur can store up to four times of energy as compared to the commercial lithium we can commonly find readily available at convenience stores around. Just imagine how we can actually increase capacity with the need of just a single natural resource. This is not only convenient but is very cost-efficient as well.
