Increased gas generated in the battery will increase the internal pressure of the battery, endangering the safety of the battery. Increasing humidity will consume more active materials in the battery, causing the battery capacity to decrease, and vice versa. .
SFY-20A lithium ion battery pole piece humidity detector can quickly measure the moisture content of electronic lithium pole pieces, including humidity in separators, graphene powder and battery raw material powder, in 3-5 minutes. results can be achieved, no consumables, convenient and practical,
Three natural enemies of lithium batteries
What will happen if too little electrolyte is injected into the lithium battery:
1. There is less electrolyte, but there are fewer lithium-ion transmission channels, which leads to an increase in internal resistance, exwater leakage inside the battery, battery leakage, battery internal short circuit and severe polarization. which causes further reactions in the lithium flakes, causing the lithium flakes to swell and bulge
2. The internal resistance is high, the capacity of the positive electrode cannot be fully exerted, the negative electrode lithium is precipitated. , and the cycle performance is poor, and it is easy to swell in the later stages of the cycle. If it is slightly less, the long cycle will be poor, and if it is too small, it will be poor. very bad at the beginning
3. For sealed batteries, too much lithium-ion electrolyte is prone to leakage. Initial efficiency has little effect, but it will reduce lifespan. small, the electrolyte will have a relative increase in resistance which will affect the first efficiency and reduce the service life. Water content in electrolyte mainly affects the transmission of lithium ions and the activity of the active material of the electrode, thereby reducing the capacity and service life. p>
4. When charging, the electrolyte will overflow from the ventilation holes and contaminate the battery shell, causing self-discharge and corrosion of the battery holder and other parts. Ventilation holes must be unobstructed and not blocked, otherwise hydrogen will escape. released during charging will cause the battery to burst.
5. First of all, you can see that the negative electrode piece should be gold. Then the gold gradually fades and slowly becomes white, with the appearance of white crystals. The lithium ions in the negative electrode part increase, so white color will appear after oxidation.
Hello, would you like to ask about the three natural enemies of lithium batteries? The three natural enemies of lithium batteries are humidity, dustand breakdowns. Lithium batteries are mainly composed of wet positive electrodes, negative electrodes, separators, electrolytes and casings. Humidity has a huge impact on its performance and structure. Dust and heavy impurities can cause micro-short circuits. inside the lithium battery, which is harmful to the lithium battery. Some failures will occur during the production, transportation and use of lithium batteries. A failure will affect the performance and reliability of the entire battery. may even cause the battery to stop working or cause other safety issues. Therefore, lithium batteries The three natural enemies are moisture, dust and breakdown.
