Battery auxiliary material detection
Test background
Electrode binder is one of the important auxiliary functional materials in lithium-ion batteries. Although it has no capacity and accounts for a small proportion in the battery, it is the main source of the mechanical properties of the entire electrode and has an important impact on the production process of the electrode and the electrochemical properties of the battery.
Lithium-ion battery binder is a polymer compound whose main function is to connect the electrode active material, conductive agent and electrode current collector to make them have overall connectivity, thereby reducing the impedance of the electrode and making the electrode sheet have good mechanical properties and processability.
Requirements for battery electrode binders
An ideal lithium-ion battery electrode binder should have the following properties:
● Good solubility, fast dissolution speed, and high solubility;
● Safe, environmentally friendly, and non-toxic solvents, with water being the best solvent;
● Large molecular weight and small amount of binder;
● Moderate viscosity, easy to homogenize and maintain slurry stability;
● Strong bonding force, and high peeling strength of the prepared electrode;
● Stable electrochemical properties, no redox reaction within the working voltage;
● Resistant to electrolyte corrosion;
● With a certain degree of flexibility, it can withstand the bending of the electrode and the volume change of the active material particles;
● Good conductivity and lithium ion conductivity;
● Wide source and low cost.
