Cellulosic Biomass-Reinforced Polyvinylidene Fluoride Separators with Enhanced Dielectric Properties and Thermal Tolerance
Safety
issues are critical barriers to large-scale energy storage applications
of lithium-ion batteries (LIBs). Using an ameliorated, thermally stable,
shutdown separator is an effective method to overcome the safety issues.
Herein, we demonstrate a novel, cellulosic biomass-material-blended
polyvinylidene fluoride separator that was prepared using a simple
nonsolvent-induced phase separation technique. This process formed
a microporous composite separator with reduced crystallinity, uniform
pore size distribution, superior thermal tolerance, and enhanced electrolyte
wettability and dielectric and mechanical properties. In addition,
the separator has a superior capacity retention and a better rate
capability compared to the commercialized microporous polypropylene
membrane. This fascinating membrane was fabricated via a relatively
eco-friendly and cost-effective method and is an alternative, promising
separator for high-power LIBs
