Abstract: This application discloses a battery cell. An electrochemical cell includes a positive electrode plate, a negative electrode plate, and at least three separators located between the positive electrode plate and the negative electrode plate. A first separator located at the middle among the at least three separators is a conductive layer.

Abstract: Embodiments of the present invention provide a method, a device, and a system for acquiring a user behavior. In the embodiments of the present invention, an acquired URL request matches a database, and the database stores a URL actively initiated by a user recognized by adopting a web crawler technology. If a URL contained in the URL request matches a corresponding URL actively initiated by a user in the database, it may be determined that the URL request is actively initiated by the user. Therefore, a network forwarding device or a server can rapidly and accurately acquire a behavior that a user actively initiates a URL request so as to further analyze a user behavior.
