An Improved Composite Polymer Electrolyte for Lithium metal Batteries

摘要

We have demonstrated that PEO-based polymer electrolytes prepared by solvent-free procedures and with the addition of particle-size ceramic powder have very stable lithium interface properties-a very important feature for the development of successful lithium metal polymer batteries. The results of cyclability tests at different charge-discharge rates carried out on prototypes of LPBs asembled with the dry prepared PEO_20-LiCF_3SO_3-20
