Batteries, Supercapacitors

Chao-Yang Wang, William E. Diefenderfer Chair in Mechanical Engineering and professor of mechanical engineering, of chemical engineering and of materials science and engineering at Penn State, has received a three-year award from the Toyota Research Institute (TRI) through the institute’s University Research Program (URP). The award will support Wang’s research on redesigning liquid electrolytes to prevent lithium-ion (Li-ion) batteries from catching fire.

A team of researchers at Penn State introduce a novel design approach that optimizes battery performance for extreme climates

Despite lithium-ion (Li) batteries’ role as one of the most widely used forms of energy storage, they struggle to operate at full power in low temperatures and sometimes even explode at high temperatures. Researchers at Penn State, however, have proposed a design that could hold the key to effective and stable power storage in a variety of climates.

Rechargeable solid-state lithium batteries are an emerging technology that could someday power cell phones and laptops for days with a single charge. Offering significantly enhanced energy density, they are a safer alternative to the flammable lithium-ion batteries currently used in consumer electronics — but they are not environmentally friendly. Current recycling methods focus on the limited recovery of metals contained within the cathodes, while everything else goes to waste.  

 Recycling does not necessarily prevent an item from eventually ending up in a landfill, according to Enrique Gomez, interim associate dean for equity and inclusion and professor of chemical engineering in the Penn State College of Engineering. Instead, recycling simply delays its end of life. Plastic bottles that are recycled and then turned into carpet, for example, eventually end up in the landfill when the carpet gets worn out and is thrown away.

The demand for high-performance batteries, especially for use in electric vehicles, is surging as the world shifts its energy consumption to a more electric-powered system, reducing reliance on fossil fuels and prioritizing climate remediation efforts. To improve battery performance and production, Penn State researchers and collaborators have developed a new fabrication approach that could make for more efficient batteries that maintain energy and power levels.

UNIVERSITY PARK, Pa. — A research lab at Penn State will equally share a three-year, $2.55 million grant from the Air Force Office of Scientific Research (AFOSR) with three other teams at Carnegie Mellon University and the Adolphe Merkle Institute of the University of Fribourg in Switzerland. The multidisciplinary research collaboration aims to develop a framework for the design and production of soft, self-charging, bio-inspired power sources for applications in space.

A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today (Oct. 12) in the journal Nature.
