In this review, recent advances in lithium battery flame retardant technology are summarized. Special attentions are paid on the flammability and thermal stability of a variety of battery flame retardant technology including flame-retardant electrolyte and separator.
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 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.
According to the provisions of safety standard for non-metallic materials in UL 2580 safety standard, the minimum flame retardant grade of the plastics used in battery pack shell materials should be V-1 in UL 94 standards test.
The study found that the heating rate is positively correlated with the onset temperature, peak temperature, and endset temperature of the endothermic peak. The flame-retardant modified polymer electrolyte for new lithium-ion batteries has better thermal stability than traditional lithium-ion battery electrolytes.
Nowadays, lithium-ion batteries on the market consist of positive and negative electrodes coated with highly active electrode materials, separators, and electrolytes. To solve the thermal safety problems of lithium-ion batteries, the design and development of electrolyte flame-retardant additives are critical.
