Embodiment 1

[0051] Take two types of slurry of the same system, numbered as slurry A and slurry B, and test them in the following ways:

[0052] 1. Place the pre-cleaned and dried container on the horizontal platform. Take the slurry to be tested and pour the electrode slurry into the solution. The operator's eyes are level with the marked line at the bottom of the container, and ensure that the slurry plane is just level with the marked line. During the process of pouring the slurry, it is necessary to ensure that the slurry does not touch the container. On the side wall above the marked line, otherwise the container needs to be washed and dried and then the above steps are repeated.

[0053] 2. Tilt the container slowly until the mouth of the container touches the horizontal surface, fix the position of the container, start timing at the same time, and set the standing time to 1min.

[0054] 3. After 1 minute, put the container on the horizontal surface stably, and read the number of t...

Abstract

The invention provides a method for detecting leveling property of battery slurry, which is used for measuring the flowing distance of the battery slurry with the set volume in a set inclined path and at set time, and then measuring the leveling property of the battery slurry according to the flowing distance. The method detects the leveling property of the battery slurry by the aid of the flowing property of the battery slurry. During detection, only the flowing distance of the quantitative slurry in the set inclined path and at the set time needs to be measured, if the flowing distance is longer, the leveling property is better, and the density of a polar plate surface prepared by the slurry is more uniform. The method is simple and convenient in operation and visual and accurate in results. Technicians in the field can determine upper and lower limit values of the flowing distance of a system of the standard slurry in advance, and when the slurry is blended, testing is performed according to the method until the flowing distance of the prepared slurry meets needs within a specified range.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to a method for detecting the leveling property of battery slurry. Background technique [0002] In recent years, with the depletion of traditional petrochemical resources and the resulting soaring oil prices and a series of problems, people's demand for new clean energy is increasing. Lithium-ion battery is a new type of power source, which has the advantages of high energy density, long cycle life and no pollution. It is currently a portable chemical energy source with the highest specific energy. Lithium-ion batteries have developed rapidly since their inception, and are now widely used in devices such as notebook computers, video cameras, mobile communication tools, and cameras. [0003] Although lithium-ion batteries have the above advantages, their rate performance needs to be improved, which is one of the reasons that limit their application in vehicle power sources. In...
