A New Study on Faster Charging Energy Storage – EQ Mag Pro


An award-winning Tulane University researcher has led a team in discoveries that could result in significantly faster charging electric vehicles and portable devices such as cell phones and laptops.

The team, engineered novel materials at the nanoscale to achieve high power and energy densities.

The new material has the potential to reduce charging times from hours to a matter of minutes.

“The performance we are getting—in terms of energy and power density—is outstanding and bridges the gap between batteries and capacitors,” the Researcher said.

One of the researchers from the team said the rightful shift toward renewable energy has led to a dire need for electrochemical energy storage devices that can handle high charging rates and have high capacity.

While lithium-ion batteries, also called Li-ion batteries or LIBS, offer one of the highest energy densities, They still struggle when it comes to high charging rates, and their electrolytes exhibit some safety concerns.

On the other hand, aqueous electrochemical capacitors, also known as supercapacitors, can deliver very high power but their energy density is limited.

Funded by the Department of Energy’s Energy Frontier Research Center (DOE-EFRC) as part of the Fluid Interface Reactions, Structures and Transport (FIRST) centre, the work revolves around MXenes, promising energy storage materials that are conductive and can host ions, such as lithium, between layers.

Room-temperature ionic liquids are promising electrolytes because they provide stability and a larger energy density. But because their ions are so large and unable to get between the MXene layers, the amount of energy stored is limited.

“Here we introduced wedges or pillars between the layers to open them up, allowing the ionic liquid ions to get stored between the MXene layers, thus achieving very high energy and power densities,” the researcher said.

He said this work exemplifies the importance of optimizing and engineering the spacing in 2D materials to unlock their potential for new applications.
