Transient technology seeks the development of materials, devices, or systems that undergo controlled degradation processes after a stable operation period, leaving behind harmless residues. To enable externally powered fully transient devices operating for longer periods compared to passive devices, transient batteries are needed. Albeit transient batteries are initially intended for biomedical applications, they represent an effective solution to circumvent the current contaminant leakage into the environment. Transient technology enables a more efficient recycling as it enhances material retrieval rates, limiting both human and environmental exposures to the hazardous pollutants present in conventional batteries. Little efforts are focused to catalog and understand the degradation characteristics of transient batteries. As the energy field is a property-driven science, not only electrochemical performance but also their degradation behavior plays a pivotal role in defining the specific end-use applications. The state-of-the-art transient batteries are critically reviewed with special emphasis on the degradation mechanisms, transiency time, and biocompatibility of the released degradation products. The potential of transient batteries to change the current paradigm that considers batteries as harmful waste is highlighted. Overall, transient batteries are ready for takeoff and hold a promising future to be a frontrunner in the uptake of circular economy concepts.

瞬态电池的降解行为、生物相容性、电化学性能和循环潜力

瞬态技术寻求开发在稳定运行期后经历受控降解过程的材料、设备或系统，留下无害的残留物。为了使外部供电的全瞬态设备比无源设备运行更长时间，需要瞬态电池。尽管瞬态电池最初是用于生物医学应用，但它们代表了避免当前污染物泄漏到环境中的有效解决方案。瞬态技术可以提高材料回收率，从而实现更有效的回收，从而限制人类和环境接触传统电池中存在的有害污染物。人们很少致力于对瞬态电池的退化特性进行分类和了解。由于能源领域是一门属性驱动的科学，因此不仅电化学性能而且它们的降解行为在定义特定的最终用途应用中发挥着关键作用。对最先进的瞬态电池进行了严格的审查，特别强调了降解机制、瞬态时间和释放的降解产物的生物相容性。突显了瞬态电池改变当前将电池视为有害废物的模式的潜力。总体而言，瞬态电池已做好腾飞的准备，并有望成为循环经济概念领跑者。
