However, since the effective contact area of existing S-TENG is only half of the total space area, the charge generation capability has not reached the optimum level. Therefore, developing an effective charge transfer mode strategy to extract maximum energy from limited space remains a challenge. Here, we propose a crossing lateral-sliding type triboelectric nanogenerator (CLS-TENG) with attached-electrode mode and full space arrangement. CLS-TENG is realized by cross-arranging dielectric layers of opposite polarity in two triboelectric layers. CLS-TENG combines the advantages of dual electrode working mode and full space arrangement of dielectric layers, and has the higher transfer charge among existing sliding basic mode. Under identical area conditions, the transferred charge in the CLS-TENG is approximately twice that of the free-standing mode TENG and twice that of the lateral sliding mode TENG. Furthermore, an integrated prototype is developed based on the CLS-TENG to achieve energy harvesting under unidirectional water flow. This study has broken through the drawback of the current sliding basic mode where space cannot be fully utilized and offer a new way for the further development of high-performance TENG.","PeriodicalId":394,"journal":{"name":"Nano Energy","volume":"35 1","pages":""},"PeriodicalIF":17.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The competitive specific adsorption in the Inner Helmholtz Plane (IHP) adjacent to the electrode determines the derivatized reduction of the electrolyte, which in turn affects the growth characteristics of the SEI. Herein, the synergistic effect of spray drying method and gas-phase fluorination method was cleverly used to construct uniform fluorocarbon (CF<sub>x</sub>) barriers in porous silicon/carbon materials to tune the composition of the IHP. The introduction of CF<sub>x</sub> effectively promotes the aggregation of Li<sup>+</sup> in the IHP, where C-F bond is electrochemically transformed into LiF and occupy the dense layer of SEI. More importantly, the preferentially generated LiF benefits the specific adsorption behavior of hexafluorophosphate (PF<sub>6</sub><sup>-</sup>) and fluoroethylene carbonate (FEC), further forming IHP-derived LiF at the inorganic interface. The robust LiF-rich skins are beneficial of accelerating Li<sup>+</sup> transfer and alleviating the elastic-plastic deformation of silicon anodes originating from large volume change upon cycling. As a result, the silicon-based composite exhibits a remarkable cycling performance with a reversible capacity of 919 mAh g<sup>-1</sup> (a high capacity retention of 90%) after 400 cycles at 3 A g<sup>-1</sup> and high rate capability of 721 mAh g<sup>-1</sup> at 5 A g<sup>-1</sup>.

These systems are prone to electrode electrolysis and bubble formation in the buffer solution. In this study, we propose a novel self-powered method based on triboelectric nanogenerators to enhance exosome production from MSCs. This approach utilizes the triboelectric effect to generate an electrical output with an open-circuit voltage of 1800V and a short-circuit current of 88µA, effectively avoiding harmful electrochemical reactions. By optimizing parameters such as current strength, electrical stimulation duration, and treatment cycles, exosome production is increased by up to 3.2 times. Further investigations reveal that the enhanced exosome production is closely linked to calcium ion influx. Moreover, exosomes produced under electrical stimulation retain their biological activity and significantly promote wound healing.
