Lithium ion non-Newtonian fluid viscosity measurement scheme

Lithium-ion batteries were born in the early 1990s and are based on lithium batteries. Lithium-ion batteries use a carbon material as the negative electrode and a lithium-containing compound as the positive electrode. There is no metal lithium, only lithium ions. This is a lithium ion battery. A lithium ion battery is a general term for a battery in which a lithium ion intercalation compound is used as a positive electrode material. The charging and discharging process of a lithium ion battery is a process of intercalating and deintercalating lithium ions.

Lithium batteries are classified into lithium batteries and lithium ion batteries. As an emerging clean and renewable secondary energy source, lithium-ion battery has the advantages of high working voltage, high energy density and light weight. Lithium-ion batteries are used in mobile phones, notebook computers, power tools, digital cameras, etc. People commonly call them lithium batteries, and real lithium batteries are rarely used in everyday electronics because of their high risk. In recent years, the application of lithium-ion batteries in the military and aerospace fields has gradually increased, and the presence of lithium-ion batteries in military communications, torpedoes, submarines, flying, and lunar exploration is also everywhere.

For the production of lithium-ion batteries, coating is a key process in battery production, which directly affects the quality of the electrodes and batteries, so the control of the battery slurry is very important. The slurry is a non-Newtonian fluid and the viscosity reflects the basic characteristics of the non-Newtonian fluid. Lithium-ion battery positive and negative slurry viscosity can not be coated, the coating determines the quality of the battery (coating is the positive and negative electrode slurry coated on copper aluminum foil and dried to make the pole piece of the battery), the electrode The quality level determines the performance of the battery. Therefore, the control of non-Newtonian fluid viscosity determination is of great significance. Brookfield is the world's leading manufacturer of laboratory and online rotary viscometers. As the world's leading manufacturer of laboratory and on-line rotational viscometers, most quality control, research and development and manufacturing processes use Brookfield viscometers as their primary choice for viscosity measurement.

The Brookfield Bolery Viscometer-DV2T Viscometer can be used to measure the viscosity of a lithium ion battery. BROOKFIELD DV2T Viscometer Quick Positioning Bracket: Press and hold the button to quickly and easily move the viscometer up and down for quick positioning and sample replacement. Ball bearing suspension system: More durable and durable sensing system, Greatly improve production efficiency and instrument life; EZ-Lock rotor quick connect system: Quick and safe installation and removal of the rotor in two simple steps, avoiding viscometer belts due to frequent rotor replacement or multi-person operation The damage that comes.
