Flame retardant polyacylonitrile/phosphinate composite-based separators for safe lithium-ion batteries |
| 초록 |
A novel heat-resistant and flame-retardant composite membrane incorporating phosphorus-rich aluminum diethylphosphinate (ADEP) into mechanically and thermally stable polyacrylonitrile (PAN) was prepared by electrospinning. To improve the heat resistance and tensile strength, the PAN-based composite membranes were partially oxidized at 210 ℃ for 30 min. From a vertical burning test under ambient conditions, it was confirmed that the flame retardancy of the PAN/ADEP composite was effectively enhanced by ADEP when more than 5 wt% was introduced into PAN. For the battery performance, the composite membrane showed highly stable electrochemical and thermal properties, including superior discharge capacity when compared to the commercial polypropylene membrane. This indicates that the developed composite membrane can be used as a flame-retardant separator for safe and high-performance lithium-ion batteries. |
