“…Bicy et al 135 cellulose/carboxylated polyimide porosity ∼ 78%; electrolyte uptake ∼ 638%; and σ ∼ 0.51 mS.cm −1 mechanical strength was enhanced through the addition of cellulose, due to an increase in the solution viscosity and so the formation of fibers with larger diameters; the prepared structure could maintain 88% of the electrolyte after 100 min at ambient temperature, which was significantly higher than the PP (∼20%); frequent H-bong donating groups in the suggested network could provide numerous channels for feasible transferring of the Li + ions. between the electrodes and the separator component enables easy migration of the Li + ions during cycling processes.…”

“…At the same time, the separator is a key factor that affects the safety property of the battery 6,7 . Generally, the separators mainly have the following basic properties: (1) Excellent mechanical strength to meet the demand of the battery manufacturing process 8 ; (2) good compatibility with electrolyte and good permeability with ions 9 ; (3) Outstanding electronic insulation and electrochemical stability 10 ; (4) Good chemical stability, no reaction with electrode or electrolyte 11 . However, in order to enhance the safety performance of lithium‐ion battery, the separator should have an excellent thermal stability to prevent the short circuit due to cathode and anode contact at high temperature, which may lead to safety accidents.…”

The separator as a main part of lithium‐ion batteries (LIBs) acts as a primary factor that affects the safety property of the battery. The pre‐oxidized PAN (OPAN) separator as an alternative separator with high temperature resistance was developed through the electrospinning of PAN by thermal stabilization. The prepared OPAN separator showed an exceptional dimensional thermal stabilization, without obvious dimensional shrinkage after treated in the oven at 300°C for 30 min, which improves the safety of LIBs at high temperatures. The OPAN separator had a high porosity and excellent affinity to the electrolyte, along with 351.3% of electrolyte uptake. Furthermore, the ionic conductivity and the interfacial resistance of OPAN separator were 1.63 mS/cm and 881 Ω, better than 0.65 mS/cm and 1463 Ω of commercial Celgard 2400 separator. In addition, the LiFePO4/Li battery assembled with OPAN separator given an outstanding initial discharge specific capacity and coulomb efficiency of 152.1 mAh/g and 97.9% and shown an excellent capacity retention ability of 92.3% after 100 cycles. The battery assembled with OPAN separator exhibits more excellent rate performance than PAN and Celgard 2400 separators at a charge current density of 0.2–3.0 C. It is believed that this excellent separator with such remarkable performances and low cost can be a promising separator candidate for safe LIBs.

“…It is widely known that the materials used for traditional battery separators are mainly polypropylene and polyethylene, but these materials have poor thermal stability and chemical corrosion resistance. Therefore, in recent years, researchers have begun to explore new types of membrane materials, including composite materials [4][5][6][7] . The types of fillers for composite materials are also considered.…”

The polyvinylidene fluoride/graphene composite membranes were prepared by electrostatic spinning under different conditions. Statistical analysis was conducted on the film-forming properties and liquid absorption rate. Scanning electron imaging technology observed the typical morphologies of the prepared membranes. The influences of process conditions, such as the graphene content, the applied voltage, the needle-collector distance, and the spinning flow rate on the typical morphology of the composites, were compared. It was found that the applied and the needle-collector distance significantly affected the thin film’s film-forming properties. In contrast, the flow rate had a smaller effect on the film properties and morphology. Comprehensive comparison results suggested that the morphology and uniformity of the fibers in the prepared composite material were relatively better at the needle-collector distance of 13 cm with a graphene content of 0.5%, the applied voltage of 18 KV, and the spinning flow rate of 0.12 μL/min.
