ABSTRACT: Lithium-ion batteries have been state-of-the-art electrochemical energy storage technology for decades, but their energy densities are limited by carbonaceous anodes and conventional liquid electrolytes can pose significant safety concerns. Lithium metal batteries featuring solid polymer electrolytes and high voltage cathodes are promising candidates for next generation devices exhibiting improved power and safety, but no solid electrolytes have been identified that exhibit the requisite electrochemical properties and thermal stability. Here, we report an interpenetrated network polymer with weakly coordinating anion nodes that functions as a high-performing single-ion conducting electrolyte, with a wide electrochemical stability window, high room temperature conductivity (1.5 × 10−4 S cm−1), and exceptional selectivity for Li-ion conduction (tLi+ = 0.95). Importantly, this material is also flame retardant and highly stable in contact with lithium metal. A lithium metal battery prototype containing this solid electrolyte outperforms a conventional battery featuring a polymer electrolyte.

BIO: Dr. Dong-Myeon Shin is appointed as postdoctoral researcher to work with Jeffrey Long at Department of Chemistry, University of California, Berkeley. He was inspired to work in nanoscience as the undergraduate and graduate researchers with Prof. Yoon-Hwae Hwang and Prof. Hyung Kook Kim at Pusan National University (BS, 2009; MS, 2011; Ph.D., 2016). His research is dedicated to developing the energy harvesting nanodevices, such as the piezoelectric and triboelectric nanogenerators, as well as energy storage devices including all solid state battery.IMG_7228_A.JPG
