“…As shown in Table S2, compared with the work of the previously reported flexible aqueous zinc-ion battery, the all-around performance has obvious advantages. [47][48][49][50][51][52][53][54][55] The pouch cell or fiber cell as the core components couples with solar panels, wireless charging, and battery indicators (Figure 6A). The "smart watch," driven by PAA-Zn/ZnF 2 @Zn||MnO 2 pouch cell or fiber cell, is used to collect the corresponding information including temperature, humidity, and pressure sensors modular integrated system, and then send the data to the mobile phone through the Bluetooth protocol.…”

Flexible aqueous zinc batteries (FAZBs) with high safety and environmental friendliness are promising smart power sources for smart wearable electronics. However, the bare zinc anode usually suffers from damnable dendrite growth and rampant side reaction on the surface, greatly impeding practical applications in FAZBs. Herein, a composite polymer interface layer is artificially self‐assembled on the surface of the zinc anode by graft‐modified fluorinated monomer (polyacrylic acid‐2‐(Trifluoromethyl)propenoic acid, PAA‐TFPA), on which an organic–inorganic hybrid (PAA‐Zn/ZnF2) solid electrolyte interface (SEI) with excellent ionic conductivity is formed by interacting with Zn2+. Both the pouch cell and fiber zinc anode exhibit excellent plating/stripping reversibility after protecting by this organic–inorganic SEI, which can be stably cycled more than 3000 h in symmetric Zn||Zn cells or 550 h in fiber Zn||Zn cells. Additionally, this interface layer preserves zinc anode with excellent mechanical durability under various mechanical deformation (stably working for another 1200 h after bending 100 h). The corresponding PAA‐Zn/ZnF2@Zn||MnO2 full cell displays an ultra‐long life span (79% capacity retention after 3000 cycles) and mechanical robustness (85% of the initial capacity for another 3000 cycles after bending 100 times). More importantly, the as‐assembled cells can easily power smart wearable devices to monitor the user's health condition.

“…A main problem for the study of the Zn anode in ZOBs is the selection of organic cathode materials when assembling full cells. Currently, PANI is generally employed to serve as the cathode of the full cell, 195,196 but the ordinary electrochemical performance of PANI hinders its large-scale commercial application. Consequently, other typical organic cathode materials with outstanding performance, such as PTO or HATN, may be more suitable for the cathode of the full cell when focusing on Zn anode protection.…”

“…123 Zeng et al proposed a direct 3D printing method to construct a novel Ag-anchored layered porous flexible zinc anode (3DP-ZA) for flexible dendrite free zinc anodes. 124 3DP-ZA anodes exhibit good inherent mechanical flexibility and structural stability: (1) interactions between the components (carbon nanotubes, graphene and cellulose) in the formulation ink drive a robust interwoven flexible network assembly in which the zinc powder is uniformly embedded; (2) 3D printing of custom macropores ensures sufficient buffer space to release stresses to accommodate volume changes and maintain post-plating/slitting structural integrity (Fig. 6b).…”
