摘要：Polymer electrolytes are promising for high-energy lithium-metal batteries due to their favorable flexibility and processability. However, it remains a significant challenge to develop a polymer electrolyte with high mechanical strength, good thermal stability, and the ability to eliminate lithium dendrites. In this work, we developed an innovative strategy to fabricate a self-healing poly(vinylidene fluoride)hexafluoropropylene/graphene oxide/borate bonds (PHGB) polymer electrolyte with high mechanical strength, good thermal stability, and the ability to eliminate lithium dendrites by integrating graphene oxide and borate bonds. The PHGB polymer electrolyte exhibits excellent thermal stability (200 degrees C), high elongation at break (202 %), and remarkable capacity retention (95.7 %), which exceeds previously reported polymer electrolytes. It is noteworthy that lithium dendrite elimination from PHGB polymer electrolytes was characterized in-situ using microscopy. It is also suitable for use in pouch cells, which retain the ability to illuminate LEDs even when subjected to varying degrees of bending. This work paves the way for the development of high-performance polymer electrolytes, which provides a new prospective toward high-energy batteries.
