Test Data

1. 1# and 2# powders are the same different batch materials, and the resistivity vs. pressure curve 2 overlaps, but according to the data analysis, the coefficient of variation of 2# is lower, indicating that the process conditions of batch 2# are more stable .

2. Diaphragm test data

Resistivity pressure curve at different positions of the diaphragm

3. Test data of standard block thickness and resistance repeatability

Repetitive measurement 20 times thickness data evaluation

Evaluation of resistance data with 20 repeated measurements

Some application scenarios

1. It is used for battery formulation design and optimization. By measuring the resistivity of different membranes to evaluate the quality of the formulation and whether the additive content is appropriate, it does not need to be made into a battery for evaluation, which can speed up the design iteration of the battery.
2. Improve the mixing and coating process. The resistivity and thickness of the membrane can be measured to evaluate whether the slurry is evenly dispersed, whether the sedimentation status, and whether the coating and baking are reasonable.
3. Formulate the process time of battery production, such as the relationship between the storage time of the pole piece in the atmosphere and the change of resistivity, so as to determine the allowable storage time of the pole piece in the production line.
4. Measure the resistivity of the solid electrolyte under pressure, and provide directions for optimizing the solid electrolyte.
5. Optimize the production process of powder materials and monitor the production quality of powder materials.
