Batteries Life Time 50 Years ?

New technology could allow batteries to last as long as 50 years: Researchers have developed a new battery technology that could hep us to create long lasting batteries than previously possible.
some of the Researchers at the U.S Department of Energy (DOE)s Oak Ridge National Laboratory (ORNL) have developed a new postulate that a battery have three main components, they are the positive cathode, negative anode and ion conducting electrolyte. These components can play only one role on each device.
In new battery design the electrolyte has duel functions. It serves as an ion conductor and also as a cathode supplement.
This co-operative chemistry, empowered by the use of an ORNL-developed solid electrolyte, discharge an extra boost to the batterys potential and extends the lifespan of the device.

The bi-functional electrolyte revolutions are the concept of conventional batteries and opens a new avenue of the design of batteries with unprecedented energy density, Chengdu Liang (ORNLs) said.
The new discovery of the researches is based on the lithium carbon fouride(CFx) chemical formula, could also lead to batteries that are safer than current ones.
A prototype battery was tested by researchers based on formula at the DOEs ORNL-Oak Ridge National Laboratory and rated paper was published in the Journal of the American Chemical Society.
When ORNL researches incorporated a solid lithium thiophosphate electrolyte into a lithium-carbon fluoride battery, the device generated a 26 percent higher capacity than what would be its theoretical maximum if each component acted independently.
The increase is caused by the co-operative interactions between the electrolyte and athode. said Liag
As the battery discharges, it generates a lithium fluoride sat that further catalyzes the electro chemical activity of the electrolyte, said Liang.
This relationship converts the electrolyte-conventionally an inactive component in capacity- to an active one.
Depending on how the battery is engineered and used, the improvement in capacity could translate into years or even decades of extra life.
We have a demand for applications for long life disposal batteries such as artificial cardiac pacemakers, radio frequency identification devices, remote key less system, and sensors, where replacing or recharging a battery is not possible or acceptable.
If you have a pace maker, you dont want to undergo surgery every 10 years to replace the battery, Liang said.
What if a battery could last 30 to 50 years? Our fundamental research is opening the possibility through a new design mechanism.The study is published as “Pushing the Theorethical Limit of Li-CFx Batteries: A Tale of Bi-functional Electrolyte. in the Journal of the American Chemical society.
