quicker battery charge holds promise for plug-in cars - lithium batteries for sale
According to a paper published Thursday in Nature, the new lithium-ion battery material has a special coating that allows it to charge and discharge dozens of times faster than the existing lithium-ion battery material
This capability enables hybrid and plug-in
More practical tools can be used to provide support in hybrid cars
Demand for wind and solar energy is on the rise, the paper said.
Byoungwoo, a graduate student at MIT, said that in terms of cars, charging and discharging capabilities are important
This paper was written with engineering professor Gerbrand Ceder.
"Rapid discharge means you can use the battery to speed up the car," Kang told CBCNews . ". ca Wednesday.
At present, the hybrid toaccelerate
Electric vehicles rely heavily on internal combustion engines.
A coating-free lithium-ion battery material similar to this new material has been used in transportation and power tool applications for about five years, Ceder said.
This battery can store a large amount of charge, but it is slow when charging or discharging energy --
A problem is blamed on the speed of the lithium ion, which helps to pass the charge through the battery.
During this process, the ions must leave one electrode, pass through the electrolyte and deposit "active" particles in another electrode.
"This is not what we see in batteries that use these materials, so there must be other issues.
"After further research, they concluded that once the lithium ion enters the inside of the particles, it can move quickly, but it has encountered difficulties when it reaches the inlet point through the surface of the particles.
"It's kind of like a big house with only one small door," he said . ".
Ceder andKang has made minor changes to the composition and processing used to make particles, so that they form a coating that allows lithium ion to quickly pass through the surface of the particles.
Using coated particles, they make a small battery that can be charged or discharged within 10 to 20 seconds, while using uncoated particles takes 6 minutes.
Because there is already an industrial practice of manufacturing lithium batteries with uncoated particles, Ceder estimates that batteries using new materials may be sold within two or three years.
Adding a coating is not difficult, says Ceder.
"It is produced when particles are synthesized.
Actually, this is not even an extra step.
"The technology has been licensed by two companies: Umicore, a material company that makes lithium particles in Belgium, and a battery manufacturer.
However, this does not mean that people must be able to charge electric cars.
Act right away.
