Electric automobiles are infinitely superior to gasoline-powered cars but they have yet to be widely adopted. One of the issues that impede this shift is the fact that electric automobiles take a long time to charge.

Increasing charging speeds

According to a TechXplore report, a team of researchers from different countries in China has successfully completed a 5.6-minute process of charging a lithium-ion battery for a 60% charge. This feat was accomplished by adding a copper coating and nanowires to the battery''s anode in order to improve ordering.

Most anodes are made from graphite and are constructed in a non-ordered slurry, which isn''t a viable method for passing along the current. In addition, the way the materials in anodes line up creates a concern about the gap between them.

The researchers focused mainly on the anode to overcome these difficulties in speeding up charging. Here''s what they did here:

Making changes to a standard graphite anode

"They first created particle-level theoretical models to enhance the spatial distributions of different sized particles and electrode porosity. They then took what they learned from the models to make changes to a standard graphite anode. They then heated and then chilled the anode, which then compressed the slurry into a more ordered material," said TechXplore.

The researchers were surprised to discover that they could charge the battery to 60% in 5.6 minutes and to 80% in 11.4 minutes. (The researchers avoided testing how long it would take to charge to 100% because that does cause damage to such batteries.)

The researchers did not specify how much money a battery would cost, and when it might be ready for production. Despite this, the development is a great one for electric automobiles everywhere.

The study was published in the journal Science Advances.

Abstract:

We demonstrate an extremely rapid-charging lithium-ion battery with 60% recharge in 6 min and a high volumetric energy density of 6C. This technique is hampered by the lack of graphite anodes'' rate design. On the basis of a dual-gradient graphite anode, we demonstrate an extremely rapid-charging lithium-ion battery with 60% recharge in 6 min.
