“…Archer's group further investigated the effect of the adsorption behavior of PEGs with different molecular weights on the stability of the Zn anode. [ 61 ] Figure 6f,g shows that the polymer chains were adsorbed in a layer‐by‐layer Langmuir‐type manner for low‐molecular‐weight PEGs. In contrast, high‐molecular‐weight PEGs resulted in multilayer polymer adsorption due to the overlap of the PEG chains in the solution.…”

Aqueous zinc‐ion batteries (AZIBs) comprising zinc anodes hold intrinsic safety and high energy density ideally for distributed and large‐scale energy storage, thus have generated intriguing properties and increasing research interests. Unlike organic batteries, AZIBs require different, sometimes even opposite design principles and preparation strategies in solvent, electrolyte, and separator. This is especially true for the polymer materials that are widely used as critical components in stabilizing metal anodes and functioning as high‐performance safe cathode materials. This review discusses the explicit compositional and structural requisite of polymeric components in AZIBs, with an emphasis on the exclusive molecular structure–property relationship that governs the stability, reversibility, and capacity of these devices. The usage of polymers is classified into five categories aligning with the primary architecture of AZIBs: separators, additives, hydrogel electrolytes, coatings, and electrode materials. The most recent advances in the structure/property interplay of polymers by novel synthesis and preparation techniques targeting stable AZIBs are summarized and discussed. The challenges and perspectives of multifunctional polymers in developing high‐performance AZIBs are also proposed.

Interface, especially the electrochemically formed solid electrolyte interphase (SEI), is significantly important for cycling stability, reaction kinetics and safety of rechargeable batteries. The structure and composition of the electric double layer (EDL) greatly affect the formation of SEI and the performance of electrodes. However, as far as we know, there isn’t review to demonstrate the theme specially. Herein, the recent substantial progress for EDL and its impact on the formation of SEI in rechargeable batteries are reviewed and discussed. Firstly, the specific adsorption of electrolyte components on electrodes’ surface and the ionic solvation structure is introduced. Furthermore, various methods for controlling EDL in different electrode systems are described. Finally, the future development of SEI via EDL is presented for improvements and breakthroughs in electrochemical performance of rechargeable batteries.

Neutral zinc‐air batteries are considered potential wearable energy storage devices due to their high theoretical energy density, superior safety, and low cost. However, the current performance of neutral zinc‐air batteries is severely influenced by the zinc anodes. The pure zinc anode can be comminuted during charge and discharge cycles due to its unstable electrode structure, resulting in the failure of electrical contact. As a result, the battery exhibits low capacity and short cycle life. In addition, the pure zinc anodes show slow reaction kinetics in neutral electrolytes, which causes the battery to perform low power density and poor energy efficiency. Besides, pure zinc anodes own high bending stiffness, which cannot meet the demands for powering flexible electronics. Herein, a new kind of hybrid zinc/carbon nanotube fiber anode with a stable electrode structure, high reaction activity, as well as high flexibility is proposed to produce high‐performance neutral zinc‐air batteries. The fabricated fiber battery showed a high specific capacity and maximum power density of 645.3 mAh g−1 and 615.8 mW g−1, respectively. Furthermore, a high energy efficiency of 71% is achieved, the highest among the reported neutral zinc‐air batteries. The entire fiber battery is highly flexible, highlighting its potential for wearable energy storage applications.
