Abstract: The present disclosure provides a flow battery and a cell stack. The cell stack includes: a first end plate; a second end plate; and at least one cell module arranged between the first end plate and the second end plate. Each cell module includes a first flow channel end plate, a second flow channel end plate arranged opposite to the first flow channel end plate, and single-cell assemblies arranged between the first flow channel end plate and the second flow channel end plate. The single-cell assemblies include at least three hermetically-assembled cell assemblies, the first flow channel end plate is provided with arch-like flow channels, the second flow channel end plate is provided with arch-like flow channels, and each arch-like flow channel is provided with a flow channel aperture in communication with the at least three hermetically-assembled cell assemblies.

Abstract: The present disclosure provides a vanadium electrolyte, a preparation method and use thereof.

Abstract: Techniques and solutions are provided for assessing the semantic difference between networking access control lists (ACLs). For example, a semantic difference can be determined between an ACL that is currently deployed on a network device and an ACL that is a candidate for deployment. The semantic difference can be presented to a user to better understand what changes would be made to network traffic flow if the candidate ACL is deployed. The semantic difference can also be used in an automated manner to perform automatic deployment of the candidate ACL.
