Potassium-ion batteries (PIBs) have attracted enormous attention due to the abundance of potassium resources, low cost, fast ionic conductivity of electrolyte and relatively high operating voltage. Despite great efforts and progress, researches on PIBs are still at the initial stage, especially in the emerging field of flexible and wearable PIBs. The inevitable challenges for PIBs include low reversible capacity, unsatisfactory cycling stability and insufficient energy density, the solution to which mostly relies on designing advanced electrodes. Binder-free electrodes have emerged as promising electrode architecture for PIBs. Such electrodes avoid the use of insulating binders, which can be designed with various synergistic functional materials to address the aforementioned PIB issues and be endowed with flexibility/wearability. In this review, we mainly summarize the recent progress on binder-free electrodes for PIBs, with the focus on the methodologies, detailed strategies and functional materials for electrode construction. One strategy for binder-free electrodes is to assemble free-standing architecture with the help of carbon nanotubes (CNTs), graphitic fibers, and other carbon or mechanically robust materials, either alone or in combination. The other effective strategy is current collector substrate-assisted direct growth, including the use of carbon cloth, metal, MXenes and other conductive substrates. Additionally, challenges and research opportunities are put forward at the end as the guidance for future development of binder-free PIB devices.

卵巢癌是女性生殖系统常见的恶性肿瘤之一,发病率仅次于宫颈癌、子宫体癌,位居第三。近年来其病死率也一直居高不下。手术联合化疗是目前治疗卵巢恶性肿瘤的主要方法,但仍然存在着较高的复发率以及易产生耐药等诸多问题,总体临床预后不佳。因此,为了改善卵巢癌的临床结局,研究新的治疗措施便成为当下研究的重点。免疫治疗,尤其是免疫检查点抑制剂治疗,作为卵巢癌的一种新型治疗方法,近年来受到广泛关注。本文将对免疫治疗新技术在卵巢癌患者中的应用和研究进行综述。
