“…Thus, the designing of an anodic interlayer should focus on the functions of inhibiting dendrite growth, protecting lithium anode, and promoting the uniform deposition of lithium. A separator in the Li-S battery can not only prevent the direct contact of cathode and anode, but also offer the transmission channels for Li + ions [38][39][40][41]. The modification on separator plays a similar role to the anodic/cathodic interlayer, and mainly by changing the pore size and structure of the separator.…”

“…From our results, attapulgite and montmorillonite show high POD-like activities. We guess it is because they contain iron [56,57], which is also contained in HRP. In addition, the surface area may also be the key point for activities.…”

Natural nanominerals (NNMs) are progressively deposited during earth’s formation. They have shown a broad range of applications from industrial catalysis, environmental treatment, and earth science to pharmaceutics due to their unique nanostructures and characteristics. Here, we first report that NNMs have intrinsic enzyme-like properties and show good biocompatibility. First, we characterized the morphology and structure of the six most representative NNMs including sepiolite, attapulgite, halloysite, montmorillonite, kaolinite, and diatomite by SEM, TEM, and XRD. Then, we quantitatively tested their peroxidase- (POD-), catalase- (CAT-), oxidase- (OXD-), and superoxide dismutase- (SOD-) like activities. The results indicate that different kinds of NNMs show varying degrees of POD-like, CAT-like, and SOD-like activities and minor OXD-like activity. Finally, we tested their cytotoxicity and found that the selected representative NNMs have no or less influence on cell viability, showing high biosafety. At present, NNMs have been widely used, mostly focusing on the physical and chemical properties, such as luminescence and conductivity. Our work promotes the understanding of NNMs, providing a new direction for the better application of NNMs.

“…The functional groups on separator formed by organosiloxane fumigation grafting can well suppress LPS diffusion and the channel structure formed by chemical tailoring can well retain the dissolved LPS. Attapulgite, a kind of natural multi-metal oxide nanorods consisting of Al, Mg, Fe, Si and O ions, was applied as multifunctional ionic sieve to capture LPS between separator and cathode by Sun et al [63] Furthermore, they find that Fe ions in attapulgite can catalyze LPS converting, faster and relative amount of polysulfide adsorbent and the conductive agent plays an important role in the performance of Li-S batteries.…”

Because lithium-ion batteries cannot meet increasing demand for power density, lithium metal batteries are expected as the next generation of rechargeable batteries. As one of lithium metal batteries, lithium-sulfur (Li-S) batteries have attracted extensive attention because of their ultrahigh power density (2600 Wh kg −1 ) and low cost of sulfur. In order to overcome problems of active material loss, volume expansion and dendritic growth of Li metal in Li-S batteries, researchers have adopted several methods such as adding electrolyte additives, electrode modification and separator modification. Among them, separator modification shows significant advantages in inhibiting the shuttle effect of lithium polysulfides. This paper reviews research progress of inhibiting the shuttle effect of Li-S batteries by the means of the separator modification in recent years, including direct design of new type of separator and physical/chemical modification of separator surface. Through extensive reading and summarizing of the research results of the separator modification of Li-S batteries, we give the possible development direction of Li-S batteries at the end of the paper.
