Due to the broad application prospect, flexible and transparent electronic device has been widely used in portable wearable devices, energy storage smart window and other fields, which owns many advantages such as portable, foldable, small-quality, low-cost, good transparency, high performance and so on. All these electronic devices are inseparable from the support of energy storage device. Energy storage device, like lithium-ion battery and super capacitor, also require strict flexibility and transparency as the energy supply equipment of electronic devices. Here, we demonstrate the development and applications of flexible and transparent lithium-ion battery and super capacitor. In particular, carbon nanomaterials are widely used in flexible and transparent electronic device, due to their excellent optical and electrical properties and good mechanical properties. For example, carbon nanotubes with high electrical conductivity and low density have been widely reported by researchers. Otherwise, graphene as an emerging two-dimensional material with electrical conductivity and carrier mobility attracts comparatively more attention than that of other carbon nanomaterials. Substantial effort has been put on the research for graphene-based energy storage system by researchers from all over the world. But, there is still a long way to accomplish this goal of improving the performance for stretchable and transparent electronic device due to the existing technical conditions.
由于具有广阔的应用前景，柔性透明电子器件已广泛应用于便携式可穿戴设备、储能智能窗等领域，具有便携、可折叠、质量轻、成本低、透明度高、性能高等诸多优点。所有这些电子器件都离不开储能器件的支持。储能器件，如锂离子电池和超级电容器，作为电子器件的能量供应设备，也需要严格的柔韧性和透明度。在此，我们展示了柔性透明锂离子电池和超级电容器的发展及应用。特别是，碳纳米材料因其优异的光学和电学性能以及良好的机械性能，在柔性透明电子器件中得到了广泛应用。例如，具有高电导率和低密度的碳纳米管已被研究人员广泛报道。此外，石墨烯作为一种新兴的具有导电性和载流子迁移率的二维材料，比其他碳纳米材料吸引了更多的关注。世界各地的研究人员在基于石墨烯的储能系统研究方面投入了大量精力。但是，由于现有技术条件，要实现提高可拉伸透明电子器件性能这一目标仍有很长的路要走。
