Dramatically longer-lasting, faster-charging and safer lithium metal batteries may be possible, according to Penn State research, recently published in Nature Energy.
The researchers developed a three-dimensional, cross-linked polymer sponge that attaches to the metal plating of a battery anode.
“This project aims to develop the next generation of metal batteries,” said Donghai Wang, professor of mechanical engineering and the principal investigator of the project. “Lithium metal has been tried in batteries for decades, but there are some fundamental issues that inhibit their advancement.”
Under additional strain, like in the fast-charging methods desired in electrical vehicles, lithium ion (Li) batteries are vulnerable to dendritic growth — needle-like formations that can reduce cycle life and potentially cause safety issues — including fires or explosions.
“Our approach was to use a polymer on the interface of Li metal,” Wang explained. The material acts as a porous sponge that not only promotes ion transfer, but also inhibits deterioration.
“This allowed the metal plating to be free of dendrites, even at low temperatures and fast charge conditions,” he said.
Wang, who is an affiliated faculty member at the Penn State Institutes of Energy and the Environment, also belongs to the Battery Energy and Storage Technology Center, a leading research institute in energy storage.
A critical component of both IEE and the BEST Center’s mission, this project brought together researchers from different disciplines within the University.
“The collaboration in this cohort really helped drive this paper forward,” Wang explained. “It allowed us to examine the different aspects of this problem, from materials science, chemical engineering, chemistry, and mechanical engineering perspectives.”
The practical applications of this work could enable more powerful and stable metal battery technologies integral to everyday life, according to the researchers.
“In an electric vehicle, it could increase the range of a drive before needing a charge by hundreds of miles,” Wang said. “It could also give smartphones a longer battery life.”
Looking to the future, the team will explore the practical applications in a large-format battery cell to demonstrate its advantages and feasibility.
Wang said, “We want to push these technologies forward. With this work, I’m positive we can double the life cycle of these Li metal batteries.”
