Abstract

An electrolyte injection method, a detection apparatus, an electrolyte injection system, and a manufacturing system for battery cells are provided. The electrolyte injection method can significantly improve the electrolyte injection efficiency. The electrolyte injection method includes: constructing an electrolyte injection curve based on the obtained electrolyte injection time and electrolyte injection volume of a battery sample; dividing the electrolyte injection curve into at least two segments so that the average slopes of two adjacent segments of electrolyte injection curves are different, and taking a connection point between the two adjacent segments of electrolyte injection curves as a target time inflection point; calculating electrolyte injection parameters according to the target time inflection point, the electrolyte injection parameters including the number of electrolyte injection operations and the electrolyte injection volume corresponding to each electrolyte injection operation; and providing an electrolyte to an initial battery according to the electrolyte injection parameters, and performing standing treatment between two adjacent electrolyte injection operations to obtain an electrolyte-injected battery. The electrolyte injection method of the present application can significantly improve the electrolyte injection efficiency.
