title: Novel Organic-Inorganic Hybrid Electrolyte to Enable LiFePO4Quasi-Solid-State Li-Ion Batteries Performed Highly around Room Temperature.
abstract: A novel type of organic-inorganic hybrid polymer electrolytes with high electrochemical performances around room temperature is formed by hybrid of nanofillers, Y-type oligomer, polyoxyethylene and Li-salt (PBA-Li), of which the Tgand Tmare significantly lowered by blended heterogeneous polyethers and embedded nanofillers with benefit of the dipole modification to achieve the high Li-ion migration due to more free-volume space. The quasi-solid-state Li-ion batteries based on the LiFePO4/15PBA-Li/Li-metal cells present remarkable reversible capacities (133 and 165 mAh g-1@0.2 C at 30 and 45 °C, respectively), good rate ability and stable cycle performance (141.9 mAh g-1@0.2 C at 30 °C after 150 cycles).
