Fast Li+migration in LiPON electrolytes doped by multi-valent Fe ions
文献摘要：
Achieving superior ionic conductivity of LiPON solid electrolyte films is critical for the solid-state thin-film batteries with high energy density.Here we describe a method of preparing LiPON with promising ionic migration capability and high work function by systematically tailoring the concentration of Fe ions doping.Fe-doped LiPON exhibits excellent ionic conductivity(1.08×10-5 S cm-1,nearly 10 times higher than the pristine LiPON),low ionic activation energy,and moderate equilibrium potential difference(ver-sus LiCoO2,0.78 V)at room temperature.The favorable ionic mobility and electrochemical stability of Fe-doped LiPON are fully confirmed.All-solid-state"Li/LiPON/LiCoO2"TFB has been successfully constructed with a large specific capacity(～36.3 μAh cm-2 μm-1 at 10 μA cm-2)and good cycle performance(87.8％capacity retention after 40 cycles).Fe with the unique d-orbital electronic structure changes the local electron density of LiPON system with the weakened electrostatic constraint of PO3N4-tetrahedrons to Li+.A low Li+migration barrier center is established around the Fe-N bridge bonds.
