Abstract
By carefully selecting a variety of additives and designing scientific experimental schemes, we have systematically studied the role of these additives in improving the performance of lithium-ion batteries. In the experiment, we used the advanced electrochemical test technology to evaluate the detailed performance of the electrolyte with different additives. The results show that some additives can significantly improve the cycle stability and high rate discharge performance of the battery, among them, fluorinated vinyl carbonate and other additives in inhibiting the internal short circuit of the battery, reducing self-discharge and improving the ionic conductivity of the electrolyte. This study not only reveals the positive effects of the electrolyte additives on the performance of lithium-ion batteries, but also mechanistically explains how the additives can improve the internal environment of the batteries. This research provides theoretical support and practical guidance for the optimized design of lithium-ion battery electrolyte, and is expected to promote the further development of battery technology to meet the growing energy demand.
