Lithium‐Ion Batteries: Flexible Composite Solid Electrolyte Facilitating Highly Stable “Soft Contacting” Li–Electrolyte Interface for Solid State Lithium‐Ion Batteries (Adv. Energy Mater. 22/2017)

Abstract

In article number 1701437, a flexible composite solid electrolyte membrane consisting of polymer and Li-ion conductive ceramic is prepared and investigated by Feng Pan and co-workers. The addition of boronized poly ethylene glycol (BPEG) oligomer not only improves its ionic conductivity, but also facilitates a better contact between the lithium metal and the electrolyte, resulting a smooth lithium interface after cycling.
