摘要： The present application provides an end cover assembly, a secondary battery, a battery module, a device, a liquid-injection method and a device thereof. The end cover assembly for the secondary battery includes: an end cover, provided with a through hole for injecting electrolyte, and including a connecting portion; a sealing assembly, configured to seal the through hole; a locking-fixing member, configured to be movable relative to the connecting portion in a radial direction of the through hole, so as to realize switching between a locked state and an unlocked state of the locking-fixing member and the connecting portion. In the locked state, the locking-fixing member presses against the sealing assembly to restrict the end cover to be separated from the sealing assembly; in the unlocked state, the end cover and the sealing assembly are separable to allow electrolyte to be injected from the through hole.

摘要： An interface system for mechanically decoupling a cooling system includes: a housing having an opening; an inset having opposite first and second sides; an interface body having first and second ends and a bore-hole open to the first and second ends thereof. The inset has a recess in the second side to accommodate the interface body. The interface body is at least partially inserted into the inset, and the inset is at least partially inserted into the opening in the housing such that the first side of the inset is inside the housing. The first side of the inset has an opening open to the bore-hole of the interface body. One end of the bore-hole is configured to slidably receive an inlet of a cooling pipe, and the other end of the bore-hole is configured to be connected, in a fluid-tight manner, with an external coolant supply or coolant discharge.

摘要： In one example, a system for a flow cell for a flow battery, comprising: a first flow field; and a polymeric frame, comprising: a top face; a bottom face, opposite the top face; a first side; a second side, opposite the first side; a first electrolyte inlet located on the top face and the first side of the polymeric frame; a first electrolyte outlet located on the top face and the second side of the polymeric frame; a first electrolyte inlet flow path located within the polymeric frame and coupled to the first electrolyte inlet; and a first electrolyte outlet flow path located within the polymeric frame and coupled to the first electrolyte outlet. In this way, shunt currents may be minimized by increasing the length and/or reducing the cross-sectional area of the electrolyte inlet and electrolyte outlet flow paths.

摘要： Systems and techniques for measuring process characteristics including electrolyte distribution in a battery cell. A non-destructive method for analyzing a battery cell includes determining acoustic features at two or more locations of the battery cell, the acoustic features based on one or more of acoustic signals travelling through at least one or more portions of the battery cell during one or more points in time or responses to the acoustic signals obtained during one or more points in time, wherein the one or more points in time correspond to one or more stages of electrolyte distribution in the battery cell. One or more characteristics of the battery cell are determined based on the acoustic features at the two or more locations of the battery cell.
