Herein, a design of flexible triboelectric generator integrated with high‐efficiency energy storage unit (FTEG‐ES) is proposed. The power generation unit is a flexible triboelectric generator (FTEG). Natural rubber and polyethylene terephthalate (PET) release film with silicone oil on the surface are used as the friction layer, and the polyvinylidene fluoride (PVDF) layer prepared by electrospinning is added compared with traditional structure to improve output performance. The flexible solid‐state capacitor made of chemical cross‐linked poly(vinyl alcohol)−H₂SO₄ hydrogel (CPH) and activated carbon is used as an energy storage unit. The test results prove that adding the PVDF layer effectively increases the output performance of FTEG. The open‐circuit voltage and short‐circuit current are increased by 19% and 47%, respectively. The short‐circuit current density and maximum output power are up to 1.30 μA cm⁻² and 100 μW cm⁻², respectively. The flexible solid‐state capacitor can store energy more efficiently than electrolytic capacitors. The charging speed of the flexible solid‐state capacitor is increased by 34.4% compared with electrolytic capacitors when charge the 1 mF capacitor to 1.5 V. Finally, the experiments show that FTEG‐ES can be used as a backup power source for low‐power devices. The feasibility of triboelectric generator applications is explored by this work.

集成有高效储能单元的柔性摩擦发电机的设计

在此，提出了一种与高效储能单元（FTEG-ES）集成的柔性摩擦发电机的设计。发电单元是柔性摩擦发电机（FTEG）。天然橡胶和表面有硅油的聚对苯二甲酸乙二醇酯（PET）隔离膜用作摩擦层，与传统结构相比，通过静电纺丝法添加了聚偏二氟乙烯（PVDF）层，以提高输出性能。由化学交联的聚乙烯醇-H ₂ SO ₄制成的柔性固态电容器水凝胶（CPH）和活性炭被用作能量存储单元。测试结果证明，添加PVDF层可有效提高FTEG的输出性能。开路电压和短路电流分别增加了19％和47％。短路电流密度和最大输出功率分别高达1.30μAcm ^-2和100μWcm ^-2， 分别。柔性固态电容器比电解电容器可以更有效地存储能量。当将1 mF电容器充电至1.5 V时，与电解电容器相比，柔性固态电容器的充电速度提高了34.4％。最后，实验表明FTEG‐ES可用作低功率的备用电源设备。这项工作探讨了摩擦发电机的可行性。
