An extended substrate screening strategy enabling a low lattice mismatch for highly reversible zinc anodes

Abstract Aqueous zinc batteries possess intrinsic safety and cost-effectiveness, but dendrite growth and side reactions of zinc anodes hinder their practical application. Here, we propose the extended substrate screening strategy for stabilizing zinc anodes and verify its availability (d substrate : d Zn(002) = 1: 1→d substrate : d Zn(002) =n:1, n = 1, 2). From a series of calculated phyllosilicates satisfying d substrate ≈ 2d Zn(002) , we select vermiculite, which has the lowest lattice mismatch (0.38%) reported so far, as the model to confirm the effectiveness of “2d Zn(002) ” substrates for zinc anodes protection. Then, we develop a monolayer porous vermiculite through a large-scale and green preparation as…
