A continuous humidity and solar-light dual responsive intelligent solid Mg-moisture battery (SMB) with a graphdiyne nanosheets array was fabricated. The integrated battery works based on a new concept of chemical bond conversion on the surface of the graphdiyne nanosheets array that is grown in situ on a 3D melamine sponge (GDY/MS). The unique structure, excellent catalytic, and semiconductor performance of GDY endows the GDY/MS with some outstanding characteristics on trapping and transferring water molecules, catalyzing HER, and utilizing solar energy, making the GDY/MS a new generation cathode for a high-performance intelligent SMB. The performance of the GDY/MS-based smart SMB (GSMB) can be continuously tuned by humidity and solar-light. The GSMB shows a significant positive correlation between open circuit potential (OCP) and humidity, while the natural band gap of GDY makes it further act as a photoelectrode to capture light and generate photoelectrons. The GSMB can be applied as a self-power humidity monitor with an ultrafast response time of <0.24 s, a recovery time of <0.16 s, and a sensitive (36,600%) respiratory sensing performance. This simple and efficient battery-made strategy represents the future development direction of self-power supply equipment, intelligent electronic devices, and intelligent battery integration.

直接生长石墨炔纳米阵列阴极集成智能固态镁水电池

制造了具有石墨二炔纳米片阵列的连续湿度和太阳能双响应智能固体镁水分电池 (SMB)。集成电池的工作原理基于在 3D 三聚氰胺海绵 (GDY/MS) 上原位生长的石墨二炔纳米片阵列表面化学键转换的新概念。GDY独特的结构、优异的催化和半导体性能赋予了GDY/MS在水分子捕集和转移、催化HER、利用太阳能等方面的一些突出特性，使GDY/MS成为新一代高性能阴极。智能中小企业。基于 GDY/MS 的智能 SMB (GSMB) 的性能可以通过湿度和太阳光进行连续调整。GSMB 显示开路电位 (OCP) 与湿度之间存在显着的正相关关系，而GDY的天然带隙使其进一步作为光电极捕获光并产生光电子。GSMB 可用作自供电湿度监测器，具有 <0.24 秒的超快响应时间、<0.16 秒的恢复时间和灵敏 (36,600%) 的呼吸传感性能。这种简单高效的电池制造策略代表了自供电设备、智能电子设备、智能电池集成未来的发展方向。
