摘要：
The lithium-metal-anode solid-liquid hybrid batteries assembled with poly (vinylidene fluoride) (PVDF) based solid polymer electrolyte membranes are promising high-energy high-safety lithium batteries for next generation. The high-performance PVDF based solid polymer electrolyte thin membranes were prepared by a large scale coating method. The PVDF based membranes could be used in the high-energy-density lithium batteries via electrochemical characterization verification, such as ionic conductivities, electrochemical windows, interface stabilities with lithium metal anode, battery performances in coin cell, etc.. The pouch-type solid-liquid hybrid batteries with an energy density of 350 W·h/kg and all-solid-state bipolar batteries were also assembled. In addition, a practical technical approach to obtain the batteries with an energy density of 400 W·h/kg was also proposed. © 2019, Editorial Department of Journal of the Chinese Ceramic Society.
