The new material will increase the charging speed of electric cars by almost 3 times

Currently, charging modern electric cars takes about 40 minutes, while gas vehicles take no more than five minutes to refuel. To compete, electric cars need to charge in less than 15 minutes.

A team of scientists from the Japan Advanced Institute of Science and Technology (JAIST) recently developed an anode fabrication approach that could lead to extremely fast charging of lithium-ion batteries.

To test the effectiveness of their anode and compare it to the more common graphite, the researchers conducted a series of experiments. The results were promising – the proposed anode material proved to be suitable for fast charging due to the improved kinetics of lithium-ion charging. What’s more, durability tests have shown that new batteries retain about 90 percent of their original capacity even after 3000 charge / discharge cycles at high rates.

One researcher believes that the extremely high charging rate of the anode material they have prepared could make it suitable for use in electric vehicles.
