Zusammenfassung:The present disclosure relates to the technical field of lithium-ion batteries, in particular to a composite pole, a preparation method and use thereof, and a lithium-ion battery containing the composite pole. The composite pole comprising a current collector and coating disposed on surface of the current collector; wherein the coating comprises active electrode material and a eutectic electrolyte; wherein the melting point and the phase transition temperature of the eutectic electrolyte are respectively higher than or equal to 60°C. The composite pole provided by the present disclosure has higher safety, structural stability, and ionic conductivity; meanwhile, when the composite pole is used lithium-ion battery, the safety and electrochemical performance of the battery can be effectively improved.
