摘要: The invention provides a composite electrolyte of lithium-air battery and preparation method the electrolyte. comprises following steps: mixing lithium salt certain additive with pyrrole ionic liquid to form solution; immersing polyvinyl acetal polymer porous film into removing residual on surface after fully adsorbing swelling film. has high room-temperature conductivity greater than 10 S/cm, wide operating temperature range electrochemical stability window or equal 5V (vs.Li/Li ), hardly volatilizes in an open semi-open working condition, shows excellent hydrophobic property, is not decomposed presence oxygen superoxide radical O2 cycle process, does generate side reaction, compatibility cathode anode, even current density; particle size discharge product Li2O2 distribution air interface can be controlled; reaction reversibility long life are ensured.
