ASU team develops new solution for mitigating Li dendrite growth by tackling plating-induced residual stress

Green Car Congress

Now, researchers at Arizona State University, with colleagues at Rice University, have used a 3-dimensional layer of Polydimethylsiloxane (PDMS), or silicone, as the substrate of lithium metal anode to mitigate dendrite formation. —Wang et al.
