Researchers at Harvard University have made a groundbreaking advancement in battery technology, developing a new solid-state battery that can recharge in just 10 minutes.

This innovative battery, a product of extensive research at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), sets a new standard for efficiency and durability in battery technology.

The key feature of this development is the use of a lithium metal anode, significantly enhancing the battery’s performance. Xin Li, Associate Professor of Materials Science at SEAS and the senior author of the paper emphasizes the importance of this breakthrough.

“Lithium metal anode batteries are considered the holy grail of batteries because they have ten times the capacity of commercial graphite anodes and could drastically increase the driving distance of electric vehicles,” Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper, said. “Our research is an important step toward more practical solid state batteries for industrial and commercial applications.”

The new battery not only charges rapidly but also demonstrates remarkable endurance. It can be charged and discharged at least 6,000 times, outperforming existing pouch battery cells. This durability marks a significant stride towards more practical and reliable batteries for various applications, including industrial and commercial use.

A major challenge in solid-state battery development has been the formation of dendrites on the anode’s surface. Dendrites are metallic projections that can grow into the electrolyte, piercing the barrier between the anode and cathode. This growth can lead to short circuits or even fires. The Harvard team’s research addresses this issue by exploring the mechanisms behind dendrite formation.

The Harvard team’s research represents a significant leap in battery technology, offering a glimpse into the future of energy storage. With its rapid charging capability and enhanced safety features, this new solid-state battery has the potential to transform the way we use and think about energy, particularly in the realm of electric vehicles and beyond.
