Application of Aluminum Hydroxide as Halogen-Free Flame Retardant in Lithium Batteries

Aluminum hydroxide is used as a flame retardant additive in Lithium batteries. The safety of Lithium batteries is critical, and batteries that are substandard or have safety hazards can cause thermal runaway and potentially cause a fire or explosion.

ATH exists in the electrolyte and separator of Lithium-ion batteries as a flame retardant additive to improve the battery’s resistance to fire. In the event of overheating or internal short circuit, ATH releases water vapor through an endothermic reaction, absorbs heat and cools the battery, thus inhibiting the spread of flames and mitigating the risk of fire or explosion.

In addition, ATH can be incorporated into different components of Lithium-ion batteries, including electrolytes, separators, and packaging materials to provide comprehensive flame retardant protection. By strategically incorporating ATH in key battery components, manufacturers can balance safety and performance, ensuring optimal battery performance while minimizing fire risk.

Finally, the addition of aluminum hydroxide fits well with regulatory requirements: Regulatory bodies such as the International Electrotechnical Commission (IEC) and various national standards organizations impose strict requirements on the safety performance of Lithium-ion batteries, including measures to prevent thermal runaway and fire hazards. Through ATH, battery manufacturers can demonstrate their compliance with these regulations and ensure that their products meet the highest safety standards.

In summary, aluminum sulfate trihydrate (ATH) plays a key role as a flame retardant additive in improving the safety and reliability of Lithium-ion batteries. Corresponding manufacturers can improve compliance with safety standards, enhance user confidence, and ensure the continued development of battery technology.
