Wind energy scavenging and storage usually can be achieved by utilizing two different separated units, such as a triboelectic nanogenerator and a Li-ion battery with need of being periodically charged. Here, we report a new strategy of implanting a flexible solid Li-ion battery (SLB) into a triboelectic nanogenerator (TENG) for simultaneously scavenging and storing wind energy into chemical energy to achieve a self-charging system. The fabricated TENG can deliver an output voltage of about 135 V and an output current of about 12 μA, which can be utilized to effectively charge the SLB in the triboelectric vibration film of TENG. The SLB can be easily charged from 1.5 V to 3.5 V in about 55 s by using a transformer and a rectifier to connect the TENG. This research provides a new route of energy scavenging and storage devices for self-charging systems.

将固体锂离子电池植入摩擦型纳米发电机中，以同时清除和存储风能

风能的清除和存储通常可以通过利用两个不同的分离单元来实现，例如需要定期充电的摩擦电纳米发电机和锂离子电池。在这里，我们报告了一种将柔性固态锂离子电池（SLB）植入摩擦电纳米发电机（TENG）中的新策略，该策略同时将风能清除和存储为化学能以实现自充电系统。制成的TENG可以提供约135 V的输出电压和约12μA的输出电流，可用于对TENG的摩擦电振动膜中的SLB有效充电。通过使用变压器和整流器连接TENG，可以在大约55 s的时间内将SLB从1.5 V充电至3.5V。
