In recent years, flexible/stretchable batteries have gained considerable attention as advanced power sources for the rapidly developing wearable devices. In this article, we present a critical and timely review on recent advances in the development of flexible/stretchable batteries and the associated integrated devices. We first provide an overview on the requirements for flexible or stretchable batteries. This is followed by the design and development strategies for free-standing flexible/stretchable electrodes. We then summarize the recent developments of flexible/stretchable electrolytes and separators as the key battery components as well as various flexible/stretchable batteries and their integrated devices. Finally, the current challenges and future perspectives in this emerging field of flexible/stretchable batteries are also discussed.

近年来，作为快速发展的可穿戴设备的高级电源，柔性/可拉伸电池已经引起了广泛的关注。在本文中，我们对柔性/可拉伸电池以及相关集成设备的最新进展提出了关键而及时的评论。我们首先提供有关柔性或可拉伸电池要求的概述。其次是独立式柔性/可拉伸电极的设计和开发策略。然后，我们总结了作为关键电池组件的柔性/可拉伸电解质和隔膜以及各种柔性/可拉伸电池及其集成设备的最新发展。最后，还讨论了在柔性/可拉伸电池这一新兴领域中的当前挑战和未来前景。
