So we combining P(VDF-HFP) polymer electrolyte and LLZO powder and painting it on the fiberglass to construct composite solid polymer electrolyte. The SEM micrographs of the with 30wt% LLZO added are shown in Fig.1. There are obvious powder have attaching to the fiberglass surface and the polymer on it. Fig.2. compared rate capability of the composite solid polymer electrolyte film and the fiberglass. Founding that the composite system can obviously increasing it.
