When the weight ratio of the NdFeB powder was 50 wt% and the interdigitated electrode gap was 2 mm, HNG achieved the best output performance. The optimized TENG can generate an open-circuit voltage (V oc), short-circuit current (I sc), and a maximum power of ∼ 54.8 V, 5.4 μA, and 99.2 μW, respectively, at a wind speed of ∼ 15.5 m/s.
According to Adamas Intelligence’s forecast (2021), in 2030, EVs alone will be responsible for around 25% of NdFeB consumption. Traction motors (for passenger and commercial vehicles, as well as bikes, scooters and motorcycles) will take 23% of the NdFeB market.
In the rotor, flexible NdFeB/EC composite films have dual-functional roles in the device: serving as a positive layer of the TENG unit and acting as magnet sources for the EMG unit. Moreover, a commercial wind cup fixed to the top of the rotor was used to efficiently harvest wind energy.
Initially, 50 wt% NdFeB powder was dispersed in a solvent of 15 mL anhydrous ethanol containing 2 g of EC, and the as-obtained suspension was mechanically stirred at a constant speed of 300 rpm with a mechanical stirrer for 40 min to form a uniform solution.
Concomitant with the evolution of novel electron-donating and electron-accepting compounds, there has been a significant augmentation in the power conversion efficiencies (PCEs) of non-fullerene organic solar cells (NFOSCs), with recorded values surpassing 19 %.
The as-prepared NdFeB/EC composite film with 50 wt% NdFeB powder can not only serve as a positive triboelectric layer of the TENG unit but can also be used as an EMG unit magnet, which gives the device a simpler structure and lighter weight than conventional HNGs.
