“…In addition, Zhang and co-workers prepared ultra-thick LiFePO 4 electrode by 3D printing technology, creating the highest areal energy density of 5.25 mWh cm À 2 until now as shown in Figure 8e. [45] The potential of LiMnPO 4 (4.1 V vs. Li + /Li) was higher than LiFePO 4 (3.4 V vs. Li + /Li), [46] but LiMnPO 4 often suffered from poor kinetic behavior and irreversible capacity because of the slow transmission of electron and Li + . [47] LiMn x Fe 1-x PO 4 integrated the excellent rate performance of LiFePO 4 and the high redox potential of LiMnPO 4 , where Fe 2 + partially replaced Mn 2 + .…”

Rechargeable zinc‐ion batteries (ZIBs) are attractive for large‐scale energy storage due to their superiority in resources, safety, and environmental friendliness. However, the lack of suitable ZIBs cathode materials limits their practical applications. In consideration of the excellent electrochemical performance of phosphate materials in monovalent ion (Li+, Na+) batteries, they were also employed as ZIBs cathode materials recently and performed well with high potential. But they also suffer from low capacity and poor conductivity, and the energy storage mechanism is not clear yet. This Review provides a state‐of‐the art overview on the developments of phosphate cathode materials in ZIBs, including NASICON‐type phosphates, fluorophosphates, olivine‐structured, layered‐structured, and novel‐structured phosphate materials mainly. This study presents the reaction mechanism and electrochemical performance of phosphate cathode materials in aqueous ZIBs, and future research directions are discussed, which are intended to provide guidance for exploring high‐potential cathode materials for ZIBs.

Zinc ion batteries (ZIBs) have been gradually developed in recent years due to their abundant resources, low cost, and environmental friendliness. Therefore, ZIBs have received a great deal of attention from researchers, which are considered as the next generation of portable energy storage systems. However, poor overall performance of ZIBs restricts their development, which is attributed to zinc dendrites and a series of side reactions. Constructing 3D zinc anodes has proven to be an effective way to significantly improve their electrochemical performance. In this review, the challenges of zinc anodes in ZIBs, including zinc dendrites, hydrogen evolution and corrosion, as well as passivation, are comprehensively summarized and the energy storage mechanisms of the zinc anodes and 3D zinc anodes are discussed. 3D zinc anodes with different structures including fiberous, porous, ridge‐like structures, plated zinc anodes on different substrates and other 3D zinc anodes, are subsequently discussed in detail. Finally, emerging opportunities and perspectives on the material design of 3D zinc anodes are highlighted and challenges that need to be solved in future practical applications are discussed, hopefully illuminating the way forward for the development of ZIBs.

Aqueous zinc-ion micro-batteries (ZIMBs) have attracted considerable attention owing to their reliable safety, low cost, and great potential for wearable devices. However, current ZIMBs still suffer from various critical issues, including short cycle life, poor mechanical stability, and inadequate energy density. Herein, the fabrication of flexible planar ZIMBs with ultrahigh energy density by interfacial engineering in the screen-printing process based on highperformance MnO 2 -based cathode materials is reported. The Ce-doped MnO 2 (Ce-MnO 2 ) exhibits significantly enhanced capacity (389.3 mAh g −1 ), considerable rate capability and admirable cycling stability than that of the pure MnO 2 . Importantly, the fabrication of micro-electrodes with ultrahigh mass loading of Ce-MnO 2 (24.12 mg cm −2 ) and good mechanical stability is achieved through optimizing the interfacial bonding between different printed layers. The fabricated planar ZIMBs achieve a record high capacity (7.21 mAh cm −2 or 497.31 mAh cm −3 ) and energy density (8.43 mWh cm −2 or 573.45 mWh cm −3 ), as well as excellent flexibility. Besides, a wearable self-powered sensing system for environmental monitoring is further demonstrated by integrating the planar ZIMBs with flexible solar cells and a multifunctional sensor array. This work sheds light on the development of high-performance planar ZIMBs for future self-powered and eco-friendly smart wearable electronics.
