In addition to the flame retardant transformation of the battery itself, battery flame retardant can also be achieved by adding protection device outside the battery, such as wrapping a flame retardant shell outside the battery or installing an automatic fire extinguishing device, etc.
The battery consists of electrolyte, separator, electrode and shell, the traditional flame retardant method of battery is to modify the components to improve its flame safety.
Latest research progress of various battery flame retardant technologies is summarized. Typical flame retardant approaches and important properties of flame retardant battery are reviewed as well. In addition, the current main challenges of the battery flame retardant technology in both academics and the industrial are analyzed carefully.
As the most flammable component of the battery, battery electrolyte plays a leading role in the flame retardant transformation of the battery. By adding flame retardants to electrolytes or preparing nonflammable solid electrolytes, the flame retardancy of batteries can be effectively improved.
In the oxygen index test, the oxygen index of the battery separator is as high as 30%, it can well meet the flame retardant requirements of batteries. Lin et al. used a non-solvent-induced phase separation method to prepare flame-retardant poly (arylene ether nitrile) (PEN) porous membranes, the preparation process is shown in Fig. 17.
In this study, a novel strategy of coating flame retardancy was adopted to prepare a highly flexible flame-retardant CPCM (FR-CPCM) by combining flexible flame-retardant coating (FRC) with flexible CPCM. Its thermophysical properties, flexibility, and flame retardancy were characterized and used for the thermal management of batteries.
