Laboratory Electrolyte Wetness Measurement System For Battery Electrolyte R&D

The Importance of Electrolyte Wetting
Electrolyte is the core part of lithium-ion battery (LIB) research and development. It is not only an important medium to ensure ion transmission, but also an important basis for the LIB to obtain high voltage and high specific energy.
Relevant parameters of the electrolyte and its wettability to the electrode and separator directly affect the performance of the LIB. The wetting effect of the electrolyte in the electrode is closely related to the compaction density,
pore size, porosity and other parameters of the electrode itself. The evaluation of the wetting effect of the electrolyte in the electrode can be used as a key indicator for the process optimization of the electrode , and can also provide a new direction for the research and development of high-performance LIBs; Similarly, as one of the main materials of lithium-ion batteries, the separator also need a good wetting performance of the electrolyte. .Therefore, it is necessary to develop a kind of equipment that can effectively evaluate and test the stability of electrolyte wettability

Traditional test methods 



Creative Solutions

1. Based on the capillary diffusion principle of electrolyte in the electrode and separator, quantitatively evaluate the difference of electrolyte infiltration;
2. Equipped with high-precision mechanical control and visual acquisition system, the test is stable and efficient;
3. It is applicable to the evaluation of infiltration of different electrodes, electrolyte, separator with different formula and process;
4. Real-time characterization of the wetting rate of the electrolyte in the sample.

Software Interface 



Application Cases

Wettability test of negative electrode of lithium-ion battery


Experiments:Select four different positions of the same negative electrode and complete four groups of repeatability tests. The test results are shown in the figure & table;

Result: the saturation curves of four repeated infiltration tests on the same negative electrode are basically consistent, and the standard deviation of the difference of the liquid level height at 50s is about 0.135, which indicates that the test consistency is good.
