Advances in the structure and composition design of zinc anodes for high performance zinc ion batteries

Abstract

In this review, we classify in detail the recent achievements in structural and composition design, including intrinsic zinc metal anodes, metal-based anodes, alloy-based anodes, carbon-based anodes, MXene-based anodes and some novel composite anodes.

Insight on the Double‐Edged Sword Role of Water Molecules in the Anode of Aqueous Zinc‐Ion Batteries

“…[72] It is generally believed that zinc dendrites are caused by uneven structure of the zinc anode surface, inhomogeneous electric field distribution, disturbance of zinc ion flux, and rampant 2D diffusion process. [73,74] In general, under an uneven zinc anode structure and a nonuniform electric field, zinc ions preferentially achieve charge transfer and deposit at energy-favorable locations in the initial stage of the battery cycle, forming small protrusions on the zinc electrode surface. Moreover, the irregular motion of zinc ions in the electrolyte, including turbulent and advective motion, can cause a nonuniform concentration gradient of zinc ions at the solid-liquid interface.…”

A physico-chemo-electrochemically coupled stable interface for high-capacity and durable aqueous zinc metal batteries

“…Currently, there have been diverse strategies reported to solve the above issues, mainly including constructing a new bulk structure 17 and surface protective layer of the anode, 18 and designing electrolytes (high-concentration salt electrolyte, deep eutectic electrolyte, and electrolyte additives). [19][20][21][22] The bulk structure design of the anode, e.g.…”

Recent advances of organic polymers for zinc-ion batteries

“…1,2 Battery systems play a crucial role in the storage and conversion of clean energy, which are applied to a wide range of multifunction products, such as handsets, electronic devices, and electronic vehicles. [3][4][5] At present, lithium-ion batteries (LIBs) are the most extensively utilized energy storage technology. 6,7 However, the increasing concerns about cost, safety, contamination and resource limitation for the continuous manufacturing of LIBs have prompted the search for alternative energy storage technologies, such as sodium-ion batteries, 8 sodium-sulfur batteries, 9 and so on.…”
