“…In comparison, commercial Zn wire shows the specific capacity of 79.90 mAh g –1 and 63.20% capacity retention after 10,000 cycles, which was caused by the formation of Zn dendrites (Figures S22 and S23). Compared with the previously reported flexible aqueous ZIB (Figure e), ,− the fiber-shaped aqueous ZIB in this work shows an extraordinarily long life span, an ultrahigh capacity retention rate, and a relatively high working voltage range (Table S1).…”

Flexible aqueous zinc-ion batteries (ZIBs) are considered as promising energy storage devices for wearable electronics due to their costeffectiveness, environmental friendliness, and high theoretical energy density. Herein, a flexible fiber-shaped aqueous ZIB is demonstrated by using a selfassembled Co 3 O 4 nanosheet array on a carbon nanotube fiber as the cathode and Zn nanosheets deposited on a carbon nanotube fiber as the anode. The cycle life span of the fiber-shaped battery is largely enhanced by a simple electrolyte dynamics engineering strategy of preadding a trace amount of Co 2+ cations in the mild aqueous electrolyte. The assembled fiber-shaped ZIB shows a high specific capacity (158.70 mAh g −1 at 1 A g −1 ), superior rate capacity, and excellent cycling life span (97.27% capacity retention after 10,000 cycles). Additionally, the fiber-shaped ZIB also shows superior flexibility, which can charge a smart watch under deformed states. This work provides new opportunities for the development of flexible, safe, and highperformance energy storage devices for wearable electronics.

[6,7] Transient electronics refer to a new class of advanced electronics that can partially or completely dissolve or disintegrate with environmentally and biologically benign byproducts at a controlled rate and lifetime when triggered by specific environmental elements such as water/ biofluids, moisture, light, or heat. [8][9][10] Transient electronic devices, combining advanced transient materials with traditional electronics processing technology, can perform like traditional electronic devices without creating additional electronic waste, which is expected to open up a wide range of biomedical applications in clinical diagnosis and treatment.…”

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.
