As a sort of cathode material with appreciable theoretical capacity, sulfur has received a lot of attention for lithium− sulfur batteries. There is extensive research focused on cathode materials. However, relatively little attention has been gained on a binder in enhancing battery performance. The binding agent is a primary component in the cathode and plays an important role in solving the sulfur volume expansion problem during the reaction. In this work, Al (III)-carboxylate metal−organic aerogels (Al-MOGs) are reported for the first time as a binder, which can anchor the diffusion of hydrophilic polysulfides in the cathode and restrain a self-discharge reaction from proceeding for the Li−S battery. In the charge−discharge system, the admirable electrochemical performance of the as-fabricated combination cathode is proven through a satisfactory initial discharge capacity and good rate performance (1391 mAh g −1 at 0.3 C and 664 mAh g −1 at 6.0 C) and a notable cyclability (902 mAh g −1 after 200 cycles at 0.3 C). Accordingly, the creation of Al-MOG gives an updated perception for high-energy-density Li−S batteries.

“…Unlike primary batteries, which have been on the market for more than 30 years, secondary batteries are capable of being charged and discharged numerous times. A secondary battery involves innumerable types of batteries including nickel−cadmium batteries, nickel−metal hybrid batteries, lithium ion batteries (LIBs), redox flow batteries, lithium−sulfur batteries (Li−S), etc . Nowadays, lithium−ion batteries (LIBs) are the primary subject of numerous studies due to their successful applications as the main energy storage device of portable devices, e. g. laptop computers, mobile phones and digital cameras, and rapidly expanding large‐scale applications, e. g. hybrid electrical vehicles (HEVs) and smart utility grids, arising from their significant energy and power density, eco‐friendliness and long‐term cycle life .…”

Secondary Li−ion batteries have been paid attention to wide‐range applications of power source for the portable electronics, electric vehicle, and electric storage reservoir. Generally, lithium‐ion batteries are comprised of four components including anode, cathode, electrolyte and separator. Although separators do not take part in the electrochemical reactions in a lithium‐ion (Li−ion) battery, they conduct the critical functions of physically separating the positive and negative electrodes to prevent electrical short circuit while permitting the free flow of lithium ions through the liquid electrolyte that fill in their open porous structure. Hence, the separator is directly related to the safety and the power performance of the battery. Among a number of separators developed thus far, polyethylene (PE) and polypropylene (PP) porous membrane separators have been the most dominant ones for commercial Li−ion batteries over the decades because of their superior properties such as cost‐efficiency, good mechanical strength and pore structure, electrochemical stability, and thermal shutdown properties. However, there are main issues for vehicular storage, such as nonpolarity, low surface energy and poor thermal stability, although the polyolefin separators have proven dependable in portable applications. Hence, in this review, we decide to provide an overview of the types of polyolefin microporous separators utilized in Li−ion batteries and the methods employed to modify their surface in detail. The remarkable results demonstrate that extraordinary properties can be exhibited by mono‐ and multilayer polyolefin separators if they are modified using suitable methods and materials.
