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.
As one of the most popular research directions, the application safety of battery technology has attracted more and more attention, researchers in academia and industry are making efforts to develop safer flame retardant battery.
Flame retardant modification of electrolyte for improving battery safety is discussed. The development of flame retardant battery separators for battery performance and safety are investigated. New battery flame retardant technologies and their flame retardant mechanisms are introduced.
Flame retardants have important theoretical research and applied value for lithium-ion battery safety. Microcapsule flame retardants based on ammonium polyphosphate (APP) and aluminum hydroxide (ATH) were synthesized for application in lithium-ion batteries.
Although adding flame retardants enhances fire resistance, it may negatively impact the SEI, resulting in degraded cycling performance. A promising alternative is grafting flame retardants onto polymer chains, which helps to minimize their adverse effects on the SEI and improves the electrochemical performance of the battery.
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.
