“…This is primarily attributed to the hydroxyl groups on the surface of the Lyocell fibers (Supporting information, Figure S9), which act as Lewis basic sites containing lone pair electrons. These hydroxyl groups can reduce the solvation structure of Li + , thereby promoting their migration. , Moreover, these groups can also form hydrogen bonds with PF 6 – , impeding its migration …”

Lithium-ion batteries have long been plagued by the safety issue of thermal runaway. Improving the thermal stability and developing the thermal shutdown function of the separators are considered reliable solutions. Therefore, in this work, a tri-layer structured nonwoven separator with a thermal shutdown function has been prepared via the papermaking method. The separator comprises a polyethylene fiber layer, a microfibrillated cellulose fibers layer, and a polyethylene terephthalate nonwoven fabric layer. The polyethylene fiber layer endows the separator with a thermal shutdown function at 135 °C. The middle polyethylene terephthalate nonwoven layer provides support, while the microfibrillated cellulose fibers adjust the pore size. The separators exhibit excellent thermal stability, no shrinkage after heat treatment at 200 °C, and a wide thermal shutdown temperature window, thereby enhancing battery safety. This research provides an approach to fabricating high-safety thermal shutdown separators.

As a key component of lithium‐ion batteries (LIBs), separator plays a crucial role in the performance and safety of LIBs. In this paper, a cellulose‐based porous membrane modified by nano CaCO3 is prepared conveniently by electrospinning. The membrane exhibits rich fibrous porous networks and uniform distribution of nanoparticles. Strengthened by CaCO3, the tensile strength of the cellulose porous membrane elevates from 4.7 ± 0.4 MPa to 7.7 ± 0.7 MPa. Besides, the modified membranes possess improved thermal stability and can maintain their original size after treatment at 150°C and 180°C. Also, the electrolyte uptake of cellulose/CaCO3 membrane is 73% higher than that of the pure cellulose membrane. Thus, the ionic conductivity of membrane achieves 1.08 mS cm−1 and the electrochemical window is about 4.8 V, which meets the practical requirements of LIBs. Significantly, with LiFePO4/Li battery this membrane can run for 230 cycles with a capacity retention of 97.4% and a discharge capacity of 149.0 mAh g−1, demonstrating the huge potential for high safety and next‐generation LIBs.
