Scientists have discovered the secret to rapid charging of lithium batteries Bashny.Net

Scientists at the University of bath and the University of Chicago in Illinois have accomplished an important discovery in the physics of lithium batteries — they realized that affects the rate of charging of the batteries and their performance.Lithium batteries — the fuel in the engine of the mobile revolution. They are used in laptops, tablets, smartphones, electric vehicles and home energy storage. But reloading usually takes considerable time. And before you develop an expedited process, scientists must first understand why the addition of charged metal atoms in the tunnel batteries structure improve their performance.

In accordance with the recent opening of large metal ions, e.g., potassium, can improve the accumulation of charge in the batteries, but why it happens is still was not clear.

An international team of researchers conducted a series of structural experiments and computer simulations and found for the first time, why adding potassium in the tunnel structure manganese oxide so positively affects the performance of the battery.

They found that positively charged potassium ions speed up the movement of lithium within the tunnels. But depends on the charging rate of the battery.

"Understanding these processes is important for the future development of the structure and materials of the battery, and may lead to the rapid charging process. This positive impact on customers and industry, says Professor Saiful Islam from the British University of bath. — The creation of new materials is the key to easier, cheaper and safer batteries, including for the production of electric vehicles, which will help to reduce carbon dioxide emissions".

To replace the existing lithium-ion batteries can come to a conductive sponge with a large surface area and high speed charging. They are made of "ORGANOMETALLIC structures", which science has long been known, but had never considered them from the point of view of electrical conductivity. published
