3. Safety hazards of membranes and electrolytes

The electrolyte of lithium-ion batteries is a mixed solution of lithium salts and organic solvents, among which the commercially available lithium salt is lithium hexafluorophosphate. This material is prone to thermal analysis at high temperatures and undergoes thermochemical reactions with trace amounts of water and organic solvents, reducing the thermal stability of the electrolyte. The organic solvents in the electrolyte are carbonate esters, which have low boiling and flash points and are prone to react with lithium salts to release PF5 at high temperatures, leading to oxidation.

4. Safety hazards in manufacturing processes

During the manufacturing process of lithium-ion batteries, electrode manufacturing, battery assembly, and other processes can have an impact on the safety of the battery. The quality control of various processes such as mixing positive and negative electrodes, coating, rolling, cutting or punching, assembly, amount of electrolyte added, sealing, and formation all affect the performance and safety of the battery. The average degree of slurry determines the average distribution of active substances on the electrode, thereby affecting the safety of the battery. If the fineness of the slurry is too large, there may be significant changes in the expansion and contraction of the negative electrode material during battery charging and discharging, which may lead to the precipitation of metallic lithium; The fineness of the slurry is too small, which can lead to excessive internal resistance in the battery. If the heating temperature of the coating is too low or the drying time is insufficient, the solvent will remain and the adhesive will partially dissolve, causing some active substances to easily peel off; Excessive temperature may cause carbonization of the adhesive, detachment of active substances, and internal short circuits in the battery.
