A stabilized PEO-based solid electrolyte via a facile interfacial engineering method for a high voltage solid-state lithium metal battery. Issue 42 (17th April 2020) - Qiu, Jiliang
Abstract : A facile interfacial engineering method was developed to achieve stable cycling of a Li/PEO–LiTFSI/LiNi0.5 Co0.2 Mn0.3 O2 solid-state battery at 4.2 V. Abstract : A facile interfacial engineering method via in situ electro-deposition was developed to stabilize the PEO-based solid electrolyte in high voltage solid-state lithium metal batteries (Li/PEO–LiTFSI/LiNi0.5 Co0.2 Mn0.3 O2 ), which demonstrate a superior capacity retention of 72.3% after 200 cycles in 3.0–4.2 V. The critical factors for the interfacial engineering method were also demonstrated in this study.
