“…The results show that the introduction of the Al 2 O 3 enhanced the mechanical strength and thermostability of the nanofibrous membranes, and also improved the stable cycle performances of the LIBs. Although the operation and procedure of the dipcoating method are facile and simple, but the main disadvantage of this method is that it is difficult to distribute nanoparticles evenly and anchored them firmly on the surface of nanofibers [29,30]. In addition, hot-pressing is another effective approach to enhance the mechanical strength of the nanofibrous membranes.…”

The separator with excellent mechanical and thermal properties are highly required for lithium ion batteries (LIBs). Therefore, it is crucial to develop novel nanofibrous membranes with enhanced mechanical strength and thermal stability. In this work, the fluorinated polyimide (FPI) was synthesized and blended with polyvinylidene fluoride (PVDF) to fabricate composite nanofibrous membranes (CNMs) via electrospinning method. Benefiting from the introduction of aromatic FPI, the prepared PVDF/FPI nanofibrous membranes were endowed with enhanced mechanical strength and thermal stability. When the FPI content increased from 0 to 30 wt%, the tensile strength of composite nanofibrous membranes enhanced from 1.57 to 2.30 MPa. Moreover, there are almost no dimensional shrinkage for the CNM-30 containing 30 wt% FPI after heat treatment at 160 °C for 1 h. Furthermore, the prepared CNMs show improved electrochemical performances in comparison with neat PVDF and commercial Celgard membranes. The electrolyte uptake and ionic conductivity of the CNMs could reach to 522.4% and 1.14 ms•cm −1 , respectively. The prepared CNMs could provide an innovative and promising approach for the development and design of high-performance separators.

“…The electronic wearable technology has created a revolution in our daily life, making possible to use portable devices for monitoring sport activities, communication, or healthcare. − Nonetheless, the current devices are rigid structures that are not always comfortable for the user: as ideal electronic wearable device would be as comfortable and adjustable as the used clothes. On the basis of that premise, an important trend in the last years has been the development of new materials on commercial fabrics or yarns. , Pioneer works in that area have shown that is possible to modify such textiles by incorporating electroactive nanomaterials that later are used for tailoring textile supercapacitors, − batteries, , Joule heaters, among others. − …”

Multifunctional wearable electronic textiles based on interfacial polymerization of polypyrrole on carbon nanotubes/cotton fibers offer advantages of simple and low-cost materials that incorporate bactericidal, good electrochemical performance, and electrical heating properties. The high conductivity of doped polypyrrole/CNT composite provides textiles that reaches temperature on order of 70 °C with field of 5 V/cm, superior electrochemical performance applied as electrodes of supercapacitor prototypes, reaching capacitance in order of 30 F g and strong bactericidal activity against Staphylococcus aureus. The combination of these properties can be explored in smart devices for heat and microbial treatment on different parts of body, with incorporated storage of energy on textiles.

“…Apart from the surface modification of PP and PE separators, energy scientists have also attempted to design advanced separators with other polymers and ceramic materials, especially fibrous materials . As one of the alternative separators, glass fiber (GF) separators are often used in supercapacitors and sodium- and potassium-ion batteries due to their high ionic conductivities. − Recently, glass fiber membranes have also started to be used as separators for lithium-sulfur batteries due to the fact that the thick GF separators can increase the uptake of soluble polysulfide intermediates and, to some degree, slow down the diffusion of lithium polysulfide from the cathode to the Li anode side .…”

Separators are key safety components for electrochemical energy storage systems. However, the intrinsic poor wettability with electrolyte and low thermal stability of commercial polyolefin separators cannot meet the requirements of the ever-expanding market for high-power, high-energy, and high-safety power systems, such as lithium-metal, lithium-sulfur, and lithium-ion batteries. In this study, scalable bendable networks built with ultralong silica nanowires (SNs) are developed as stable separators for both high-safety and high-power lithium-metal batteries. The three-dimensional porous nature (porosity of 73%) and the polar surface of the obtained SNs separators endue a much better electrolyte wettability, larger electrolyte uptake ratio (325%), higher electrolyte retention ratio (63%), and ∼7 times higher ionic conductivity than that of commercial polypropylene (PP) separators. Moreover, the pore-rich structure of the SNs separator can aid in evenly distributing lithium and, in turn, suppress the uncontrollable growth of lithium dendrites to a certain degree. Furthermore, the pure inorganic structure endows the SNs separators with excellent chemical and electrochemical stabilities even at elevated temperatures, as well as excellent thermal stability up to 700 °C. This work underpins the utilization of SNs separators as a rational choice for developing high-performance batteries with a metallic lithium anode.
