Free QuoteDue to the nature of polymer materials, the modification and improvement of polymer-based separators in terms of thermal stability and high safety are limited. Ceramic-based separators are the future solution for addressing the root cause of battery thermal runaway. Figure 5. Separator classification. 5. Research Progress of High Safety Separator
Thermal shutdown is achieved through the expansion of microspheres. These separators are based on PVDF-HFP with different amounts of microspheres. PVDF-HFP/15 wt% of microspheres show excellent cycling behavior and thermal shutdown. Battery separators with thermal shutdown capabilities have been developed to improve battery safety.
The thermal safety separator focuses on having a higher melting point and lower thermal shrinkage than the commercial LIB polyolefin separator. Thermal-shutdown separators would prevent the thermal runaway by shutting down the battery's electrochemical reaction.
Polymeric separators are widely used in various battery technologies, particularly lithium-ion batteries. These separators are typically made from polyethylene (PE) or polypropylene (PP). Polymeric separators offer excellent dielectric properties, thermal stability, and mechanical strength.
As the understanding of TR mechanism deepens, it is evident that numerous exothermic reactions between substances in the battery are closely linked to separator. Consequently, the functional design and development of thermal runaway-blocking separators (TR-blocking separators) are regarded as key strategies for mitigating TR.
The separator is a key component of lithium-ion batteries. It plays a crucial role in battery safety, serving as one of the most effective measures against internal short circuits.Separator failure is a direct cause of the thermal runaway and can be specifically divided into three categories: puncture, melting, and thermal shrinkage.
