We proposed a microfiber with ZIF-8 coatings for lithium-ion battery electrolyte leakage detection at ppm level, with a sensitivity of 4.5 pm/ppm and a detection limit of 43 ppm in the 0-800 ppm range.
In addition, the danger threshold of the external resistance of the electrolyte leaking battery is determined by considering the balance current of the BMS. Therefore, an online method for detecting electrolyte leakage is proposed on the basis of the battery number, the linear relationship between ΔV max and cycle, and the external resistance.
As known, the leakage of lithium battery (LIB) electrolyte is an important cause for runaway failure of LIB, so it has great significance to develop an approach for electrolyte leakage detection with low detection limit and fast response.
All the above studies show that the detection of electrolyte leakage is expected to become an effective way to solve the safety problem of LIB. However, the gas sensor based on organics has the disadvantages of low response sensitivity, poor stability and easy aging.
It can be seen that the battery resistance of first 14 cycles with electrolyte leakage is distributed in the normal range, while the 15th and 16th cycle resistance are obvious outliers.
In the presence of electrolyte leakage, not only will the content of the battery electrolyte decrease but the electrolyte will also continue to react with various components of air , resulting in decomposition and a change in the electrolyte composition.
The detection limit of the sensor for diethyl carbonate is as low as 1.4 ppm, and the leakage of 200 nL electrolyte can lead to a 3% response . All the above studies show that the detection of electrolyte leakage is expected to become an effective way to solve the safety problem of LIB.
