A piece of common cellulose paper but with outstanding functions for advanced aqueous zinc-ion batteries

Regulating zinc deposition behaviors by using a functional PANI modification layer on a separator for high performance aqueous zinc-ion batteries

“…Wang et al introduced an intermediate membrane of cellulose paper between the anode and the separator, the affinity between zinc ions and the separator can be weakened, and interlayer engineering can induce the lateral growth of zinc and mitigate the accumulation of zinc ions and by-products at the zinc negative electrode. 22 Furthermore, one feasible solution is to prepare a new separator to replace the GF separator, such as cellulose film (CF), 23 Nafion, 24 or polyacrylonitrile (PAN) nanofiber separators. 25 However, the preparation process of the intermediate membrane and new separator is complicated.…”

Strategies for addressing the challenges of aqueous zinc batteries enabled by functional separators

“…Recently, GF sandwiched between two layers of cellulose paper (CP) was used as a separator (CP–GF) by Yang et al in an NH 4 V 4 O 10 //Zn full cell to simultaneously alleviate the issues of shuttle effect and formation of dendrites. 99 Firstly, the cell with the CP–GF separator presented much better cyclic stability than that with the GF separator at 4 A g −1 (Fig. 13a).…”

Improved Strategies for Separators in Zinc‐Ion Batteries

“…developed the Janus separator by utilizing a spin‐coating technique to apply sulfonamide cellulose to one side of a commercially available GF separator, thus creating two graphene sheets in parallel (Figure 3d). [47] The Janus separator is able to maintain the growth of Zn in the direction of locked Zn (002) weave crystallization, thus preventing the formation of dendrites. The separator is designed to prevent the passage of SO 4 2− , while simultaneously allowing H + and Zn 2+ to pass through, thus avoiding any potential side reactions.…”
