1. Principle of Electrode Wetting
The Lucas–Washburn Equation is commonly used to describe the dynamic of liquid absorption in electrode pores, as represented by the equation below:
- r represents the radius of the capillary (m),
- σ represents the surface tension of the imbibition fluid (N/m),
- η represents the viscosity of the imbibition fluid (Pa*s),
- θ represents the contact angle of the wet phase (°),
- h represents the liquid suction height (m),
- t represents the liquid suction time,
- cr represents a fixed value, called the formal radius.
2. Applications
- Electrolyte performance evaluation
- Electrode consistency assessment
- Material / electrode surface-treatment process optimization
- Battery performance prediction
- Production process improvement
- Research & development(R&D)
