the same electrochemical energy storage and methods for preparing

There is proposed a method (400) for producing an electrochemical energy storage device. In this case, the electrochemical energy storage device to an electrode assembly and a housing. The method (400) comprises a step of introduction (410) of an aerosol to a surface to be coated of the electrode assembly. In this case, particles of the aerosol are precipitated on the surface to be coated to form an ion-conducting and electrically-insulating separator layer. Also, the method (400) to a step of installing (420) of the electrode assembly having the separator formed in the housing of the electrochemical energy storage device to produce the electrochemical energy storage.
