This type of battery could potentially be made twice as light as a lithium-ion cell, using cheap, earth-abundant materials; however, Li-S batteries are not currently commercially viable because they tend to die after only a few recharge cycles. This work could lead to better batteries for electric vehicles, as well as other applications where low weight is critical. While at UW, Dion was a graduate fellow at the Clean Energy Institute. After completing his Ph.D. in 2019, Dion joined Gao Liu's Applied Energy Materials group at Lawrence Berkeley National Laboratory as a postdoctoral scholar. The group focuses on synthesis and processing of energy materials, including energy storage materials, solar energy materials, high performance materials and prototype development based on modern computational, synthesis and processing methods.
