Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a batching cylinder capable of accurately measuring viscosity. Background Art

[0002] Lithium batteries are new high-energy batteries developed in the 20th century. They can be understood as batteries containing lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers). They can be divided into lithium metal batteries (rarely produced and used) and lithium ion batteries (now used in large quantities). Due to their advantages such as high specific energy, high battery voltage, wide operating temperature range, and long storage life, they have been widely used in military and civilian electrical appliances, such as drones, electric vehicles, energy storage, and various types of electric tools. The industrial scale of new energy vehicles, energy storage, and other fields will maintain an exponential growth trend in the next few years, which will greatly stimulate the production demand for lithium ion batteries.

[0003] When measuring the viscosity of battery slurry, the viscometer is affected by temperature, stirring speed, measurement position and other factors, resulting in inaccurate viscosity, which affects the batching and coating process. Among them, temperature, stirring speed and measurement position are important factors affecting the viscosity of lithium battery slurry.

[0004] From the patents searched so far, the batching tank and the viscometer are separate and do not exist in the same device or apparatus at the same time. Generally, when the viscosity of the slurry in the batching tank needs to be measured, it needs to be taken out and measured with a viscometer. In this way, the consistency of the external environment (such as temperature and other factors) cannot be guaranteed, resulting in the accuracy of the measured slurry viscosity being affected. At the same time, once the viscosity needs to be measured multiple times, this step will become cumbersome, increasing production time and thus reducing production efficiency. Utility Model Content

The viscosity test is performed directly in the batching cylinder, avoiding the influence of external environmental factors on the viscosity of the slurry, thereby affecting the accuracy of the viscosity data. The batching and viscosity measurement steps are completed in one step, which directly shortens the measurement time, improves production efficiency, and can also control the viscosity test at the same temperature.

[0014] 2. The batching cylinder that can accurately measure viscosity starts the motor to drive three viscometers to move down through the hole. The three viscometers extend into the interior of the batching cylinder to test the slurry inside the batching cylinder. The three viscometers can perform viscosity tests at different positions, making it easy to read viscosity data at different locations. BRIEF DESCRIPTION OF THE DRAWINGS
