“…[92] The thickness of the separators typically varies between 25 and 40 µm, depending on the type of battery, they show a degree of porosity larger than 40% with an average pore size below 1 µm and are stable at temperatures up to 150 °C.

For the proper design and evaluation of next‐generation lithium‐ion batteries, different physical‐chemical scales have to be considered. Taking into account the electrochemical principles and methods that govern the different processes occurring in the battery, the present review describes the main theoretical electrochemical and thermal models that allow simulation of the performance of lithium‐ion batteries, including different materials and components (electrodes and separators) and battery geometries. As the separator plays an essential role in the performance and safety of lithium‐ion batteries, the recent theoretical simulation work for this battery component are shown, with particular emphasis on morphology, dendrite growth, ionic transport, and mechanical properties. Further theoretical simulations and modeling of this battery component are still required for improving performance, taking into consideration varying geometric parameters such as pore size, porosity, and tortuosity as well as the optimization of the lithium diffusion process and ionic conductivity value. Theoretical simulations of battery separators will play an essential role in the new generation of lithium‐ion batteries, allowing the improvement of their performance while reducing experimental probes and time.

“…In this case, their high theoretical capacity (1675 mA h g −1 ) and energy density (2600 W h kg −1 ) make lithium-sulfur batteries (LSBs) a promising candidate to replace LIBs. [4][5][6][7] The high capacity of LSBs originates from their internal redox reaction, which can be described as S 8 + 16Li + + 16e − # 8Li 2 S. During the discharge process, metal lithium will be oxidized to release Li + and e − , and a current is generated via the migration of e − . [8][9][10] During the charge process, solid Li 2 S will be oxidized to S 8 .…”

“…Although the shuttle effect can be effectively suppressed by modifying the PP separator, the PP separator still has some inherent disadvantages. Firstly, it has poor thermal stability, which leads to poor high temperature safety of the separator and increases the safety hazard of the battery [25,26]. Secondly, the PP separator displays low wettability which reduces the electrochemical performance of the separator to a certain extent [27,28].…”

Lithium-sulfur batteries (LSBs) have attracted extensive attention due to their high energy density and low cost. The separator is a key component of LSBs. An excellent LSBs separator requires not only good electrolyte wettability, but also high thermal stability, good tensile mechanical properties, green environmental protection potential and enough inhibition of shuttle effect. In this paper, composite separator Bacterial cellulose/Ketjen black-TiO2 (BKT) was prepared by coating the green and environmentally friendly bacterial cellulose (BC) substrate with KB-TiO2 material. BKT not only demonstrates higher electrolyte wettability, but also displays thermal stability and tensile resistance to enhance the safety of the battery. The high ratio of TiO2 and KB on the BKT surface provides chemical and physical adsorption of lithium polysulfides (LiPSs), thereby inhibiting the shuttle effect and increasing the cycle life of LSBs. The secondary current collector formed by TiO2 and KB can also reactivate the adsorbed LiPSs, further improving the capacity retention rate of the battery. Therefore, the LSBs assembled with the BKT separator exhibited an initial discharge capacity of 1180 mAh × g−1 at a high current density of 0.5 C, and maintained a specific discharge capacity of 653 mAh × g−1 after 100 cycles was achieved. Even at 2.0 mg × cm−2 sulfur areal density and 0.1 C current density, the BKT separator based battery still has an initial discharge specific capacity of 1274 mAh × g−1. In conclusion, BKT is a promising lithium-sulfur battery separator material. sulfur areal densities.
