Implanting a Solid Li-ion Battery into a Triboelectric Nanogenerator for Simultaneously Scavenging and Storing Wind Energy

Implanting a Solid Li-ion Battery into a Triboelectric Nanogenerator for Simultaneously Scavenging and Storing Wind Energy
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 135V 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 1.5V to 3.5V in about 55s 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.
