Li-ion batteries have learned to charge 5 times faster

Lithium-ion batteries are actively used for portable electronics, electric vehicles

tools and portable electrical appliances and for storing solar energy.

However, the main disadvantage of these batteries is the low charging speeddue to a side reaction where lithium ions are placed in graphite particles too quickly. 

Lithium plating occurs when the lithium ion moves too fast and the graphite particles in the battery cannotWhile charging, this can be dangerous and cause the battery to catch fire or explode. 

We have designed an experiment that can visualize what happens to the negative electrode during charging.We can see the graphite particle — the material in the negative electrode — and what happenswhile charging the battery in real time.Now we understand the physics of this process.Thanks to this, it is possible to eliminate limitations and improve the charging performance of the battery.

Thanks to this, Gao believes, it is possible to create a car battery that charges five times faster than usual, or in just 10 minutes.Also, with the help of this technology, it will be possible to charge in 10 minutessmartphone. 

According to the authors, the latest type of high-speed charging can be implemented for smartphones in 3-5 years, and for electric vehicles in 5-10 years.
