Abstract
The present invention relates to an electrochemical element and a method for producing same, the electrochemical element comprising: electrodes comprising a composite of active material and conductive material having a nanofiber structure; and a cellulose nanofiber separator combined with the electrodes. The electrochemical element according to the present invention obviates the need for separate binder and electrode current collector, has a stable interfacial surface due to the physical union of the separator and electrode, can assure superb mechanical and physical properties, and can maintain stable battery performance even against deformations due to a variety of external impact.
