摘要We introduced the nanoconcept in the oxide solid electrolyte Li7La3Zr2O12(LLZO). All-solid-state Li/LiFePO4(LFPO) cell using this solid electrolyte with thickness of several micrometers was assembled with appropriate solvent, dispersant, adhesives, and surfactant without cold- or hot-pressing. At room temperature, the Li/LLZO/LFPO cell showed the first discharge capacity of 160.4 mAh g-1, which was 94.4% of the theoretical capacity of LFPO, and the cell provided a discharge capacity of 136.8 mAh g-1after 100 cycles. At 60 °C, the battery presented more stable electrochemical performance. The capacity loss during cycles 2-100 was only 0.06% (0.7 mAh g-1). The excellent performance could be attributed to the ultrathin solid electrolyte film. (Graph Presented). © 2017 American Chemical Society.
