How to test lithium ion battery electrolyte liquids?

Since the electrolytic solution will continue during a lithium-ion battery, an oxidation and reduction reaction occurs in the positive and negative electrode, the amount of liquid liquid is less disadvantageous to the cycle life of the lithium-ion battery, and if the number of electrolytes is too small, it can also cause Some active substances cannot infiltrate, which is not conducive to the performance of the lithium-ion battery capacity, but the amount of liquid liquid will cause the energy density of the lithium ion battery to decrease, and therefore, how to determine the appropriate amount of liquid, related lithium The balance between ion batteries in performance and cost is especially important. Lithium-ion battery electrolytic solution is slightly less, less, serious less, this is a general statement, no strict requirements. Even slightly slightly less, the lithium-ion battery is already a defective product.

The electrolytic liquid is slightly smoker, which is not easy to discover. At this time, the capacity and internal resistance of the battery are normal, and the lithium ion battery electrolyte slightly less battery cell has three types of ways: remove the core, weigh, Detection. 1.

Splifting the core is a destructive experiment and can only test a battery at a time, although it can be intuitive and accurately determined, but actually use this method to screen the battery basics. 2. Weighing this method is low, because the pole, aluminum plastic film, etc.

also have a weight difference; the lithium-ion battery electrolyte is slightly less, then the actual amount of liquid flow will not The gap is very large, so that other materials are different, which is likely to be greater than the difference in the weight of the electrolyte. Of course, it is possible to measure the amount of liquid content or the amount of liquidation of each cell or the amount of liquidation amount of the liquid, but it is not as strong as the whole battery, which is not as strong as the full-cell core. And optimize the process,.

3. Exploring this is the key point of the problem, and what kind of detection method can screen the electrolyte slightly less battery cell, which is an abnormality. Currently, only two ways can measure capacity, and internal resistance is normal, but the electrolyte is slightly low.

These two methods are: cycling, magnification discharge platform. .
