“…In fact, the research on transient energy storage devices is still in its infancy, and there is still a long way to achieve the practical application of transient energy storage devices. Although researchers have conducted comprehensive and in-depth research on electrolyte materials suitable for energy storage devices such as lithium batteries, [31][32][33] ZIBs, [34,35] and supercapacitors, [36,37] there are few reports on degradable solid-state electrolytes.…”

Transient devices represent an emerging type of electronics whose main characteristic is the constituent materials that could fully or partially dissolute or disintegrate by chemical or physical processes after completing the mission, and are considered as new research directions for implantable devices. However, research on transient devices is still in its infancy and there are many challenges to overcome, especially the development of transient energy devices is relatively slow. Here, an implantable, biodegradable transient zinc ion battery (TZIB) that assembles a carefully designed cellulose aerogel-gelatin (CAG) solid electrolyte. The new fully degradable CAG solid electrolyte allows TZIB to achieve controlled degradation and stable electrochemical performance, at the same time maintaining excellent mechanical properties. The entire battery device can be completely degraded within 30 days in the buffered proteinase K solution. More importantly, TZIB has excellent electrochemical performance while meeting controlled degradation, providing a specific capacity of 211.5 mAh g −1 at a current of 61.6 mA g −1 and a wide voltage range (0.85-1.9 V). These results demonstrate the potential of TZIB in future clinical applications and provide a new platform for transient electronic technology.

“…Accordingly, aqueous zinc‐ion batteries (AZIBs) come to prominence in view of the extensive zinc sources (zinc is several times more abundant than lithium in the earth's crust), tremendous energy density (820 mAh g −1 , 5851 mAh cm −3 ), and tiny security risk 7 . − 9 On the other hand, low redox potential (−0.762 V vs. standard hydrogen electrode) allows Zn metal to be a candidate which could be directly employed as a safe anode in an aqueous metal‐ion battery. A weakly acidic zinc salt aqueous solution is non‐toxic and environmentally friendly as the electrolyte, permitting the battery to be assembled in the air, which will greatly reduce production costs at the same time.…”

The need for large‐scale electrochemical energy storage devices in the future has spawned several new breeds of batteries in which aqueous zinc ion batteries (AZIBs) have attracted great attention due to their high safety, low cost, and excellent electrochemical performance. In the current research, the dendrite and corrosion caused by aqueous electrolytes are the main problems being studied. However, the research on the zinc metal anode is still in its infancy. We think it really needs to provide clear guidelines about how to reasonably configure the system of AZIBs to realize high‐energy density and long cycle life. Therefore, it is worth analyzing the works on the zinc anode, and several strategies are proposed to improve the stability and cycle life of the battery in recent years. Based on the crystal chemistry and interface chemistry, this review reveals the key factors and essential causes that inhibit dendrite growth and side reactions and puts forward the potential prospects for future work in this direction. It is foreseeable that guiding the construction of AZIBs with high‐energy density and long cycle life in various systems would be quite possible by following this overview as a roadmap.
