- lithium ion rechargeable battery

Sarah Griffiths released: EDT 10: 03 on July 30, 2014 | update: EDT 12: 58 on July 30, 2014, many of us have a smartphone that only charges for a few hours, or because the battery is almost "dead ", laptops are no longer portable.
But this frustration may have become a thing of the past, as scientists have accurately pointed out why rechargeable batteries degrade so quickly that they force consumers to replace or upgrade their devices.
Experts say laptops and smartphones may have longer lives.
Lasting lithium-ion batteries and electric vehicles in the future can even be fully charged for more than 30 years.
In two separate studies published in Nature Communications, researchers in the United StatesS.
Doe has revealed why the battery has lost its ability to keep it charged over time.
Although the basic form of the battery has existed around 200, until now, scientists do not understand why the battery will lose all its power over time, so to solve this problem, I have done a lot of work.
But because of spending cuts, this has changed over the past decade.

According to the Journal of the Smithsonian Institution, physicists have studied the charging and discharging processes of lithium-ion batteries, which are used in many devices and point fingers to microscopic loopholes in the structure of the battery and the accumulation of tiny crystals.
Physicists have found that tiny weaknesses randomly guide lithium ions through the battery, eroding the battery in an irregular way, and reducing the efficiency of the battery.
They also noticed the deposition of nano-materials.
The scale crystals produced by the chemical reaction cause the flow of ions to become more irregular each time the battery is charged.
Using the battery at a higher voltage can aggravate this irregularity and reduce the life of the battery.
Hopefully, these findings will lead to a longer period of development.
Long-lasting, smaller, and more powerful batteries that allow phones and laptops to work longer with full power.
Some experts believe that the answer is to protect the surface of the battery or cathode with a very thin film.
Huolin Xin is a material scientist at the Brookhaven National Laboratory in New York.
The authors of both studies believe that battery prices for electric vehicles will fall sharply.
As scientists learn more about battery efficiency, he says, they can make electric car batteries that last for more than 30 years.
