Low-Cost Lithium Sulfur Batteries Could Quadruple Life


When lithium-ion batteries were first introduced as replacements for older, heavier nickel-metal hydride (NiMH) batteries, they offered a breakthrough in greater energy density and only today buy discount viagra online lighter weight. This technology has made its way through the field of generic levitra mexico consumer electronics, and lithium-ion batteries are now ubiquitous. The next step in battery technology may come from the theglobalobservatory.org University  of Waterloo, where Dr. Linda Nazar is working to develop lithium-sulfur batteries with promising characteristics including three to five times the storage of current lithium-ion batteries.

While most current electric vehicles and hybrids, including the Toyota Prius and the Honda Insight, use NiMH batteries, lithium-ion is beginning in their next generation as well. The Tesla Roadster uses lithium-ion batteries as will the Chevy Volt. A lithium-sulfur battery of comparable weight for a vehicle could significantly extend its range, allowing for more flexible use in an all-electric mode. Or, with the increased energy density available, a vehicle with a similar range could be made significantly lighter through the use of a much smaller lithium-sulfur battery.

Sulfur is currently a component in other large scale storage systems, such as sodium-sulfur batteries, but those require high temperatures and are better suited to fixed location applications, such as grid storage, rather than for portable use. Lithium-sulfur batteries may make sulfur storage energy available in a more portable form.

The lithium sulfur batteries are created by creating assemblies of carbon nanorods that are coated with molten sulfur to buy generic levitra online fill the voids. The nanoscale structure sets up conditions to keep the we use it real viagra sulfur in contact with the carbon, allowing for the repeated charging and discharging necessary for useful rechargeability.

Lithium sulfur batteries have the potential to significantly reduce the size of batteries because they have a higher energy density than other comparable lithium-based batteries.

“This composite material can supply up to nearly 80 percent of the theoretical capacity of low cost viagra sulphur, which is levitra online us pharmacy three times the energy density of lithium transition metal oxide cathodes, at reasonable rates with good cycling stability,” said Dr. Nazar.

Sulfur's availability and low cost may help bring this technology  to market. The research team has filed for patents on legal to purchase online tramadol their process and are working on developing it commercially. According to a press release announcing the research publication, sulfur is a less-expensive material than many others used in lithium-based batteries. "It has always showed great promise as the ideal partner for a safe, low cost, long lasting rechargeable battery, exactly the canada cheap viagra kind of battery needed for energy storage and link for you canadian rx cialis transportation in a low carbon emission energy economy."

I think we have and will see alot more of this type of story, as the pressure to make a better battery comes in the form of EVs, it will be made. Where as the pressure from laptop and consumer electronics isn't as great and battery life isn't a big factor given how quick and easy it is to levitra best price recharge your ipod everyother day.

I think this is the 4 or so story like this I've read, from the stanford wire battery to li-air battery recently

I don't think lithium is a viable solution for eco-friendly cars, based on the limited quantities that are available. It seems we'd be trading oil dependency for lithium dependency, and both are limited resources.

I think Zinc-Air, and NaNiCl batteries should be explored first before the automotive industry commits to lithium.

Hi,



Thanks for writing such an interesting article. Its really good to know about the batteries in detail. Seriously do we realize how many things in your house that need batteries? Let’s count it, from the flashlight, cell phone, iPod, cameras, and many more. Knowing it should make us realize on how essential the presence of viagra 50mg the batteries in our daily life. However, with that so many kinds of battery, which is generally different between one to another, sometimes we have some difficulties in finding the it's great! discount drug viagra desired type.



Find the right batteries supplier is not hard if you check out batterystation.co.uk because this website provides the widest selection of batteries and you can choose the right battery based on the categories. You can get the procell batteries which available in several sizes and voltage. You also can find Duracell batteries that divided into duracell plus batteries and duracell ultra batteries. All of the batteries come with cheaper price because this website provides the discount batteries in bulk, wholesale, and retail quantities.



Thanks,

- Andrew Morales
