Self-charging power systems collecting energy harvesting technology and batteries are attracting extensive attention. To solve the disadvantages of the traditional integrated system, such as highly dependent on energy supply and complex structure, an air-rechargeable Zn battery based on MoS/PANI cathode is reported. Benefited from the excellent conductivity desolvation shield of PANI, the MoS/PANI cathode exhibits ultra-high capacity (304.98 mAh g in N and 351.25 mAh g in air). In particular, this battery has the ability to collect, convert and store energy simultaneously by an air-rechargeable process of the spontaneous redox reaction between the discharged cathode and O from air. The air-rechargeable Zn batteries display a high open-circuit voltage (1.15 V), an unforgettable discharge capacity (316.09 mAh g and the air-rechargeable depth is 89.99%) and good air-recharging stability (291.22 mAh g after 50 air recharging/galvanostatic current discharge cycle). Most importantly, both our quasi-solid zinc ion batteries and batteries modules have excellent performance and practicability. This work will provide a promising research direction for the material design and device assembly of the next-generation self-powered system.
集成了能量收集技术和电池的自充电电源系统正受到广泛关注。为了解决传统集成系统的缺点，如高度依赖能源供应和结构复杂等问题，本文报道了一种基于MoS/PANI阴极的空气可充电锌电池。受益于聚苯胺（PANI）优异的导电性去溶剂化屏蔽作用，MoS/PANI阴极展现出超高容量（在氮气中为304.98 mAh g，在空气中为351.25 mAh g）。特别地，该电池能够通过放电阴极与空气中的氧气之间自发的氧化还原反应的空气可充电过程，同时收集、转换和存储能量。这种空气可充电锌电池具有高开路电压（1.15 V）、可观的放电容量（316.09 mAh g，空气可充电深度为89.99%）以及良好的空气再充电稳定性（经过50次空气再充电/恒电流放电循环后为291.22 mAh g）。最重要的是，我们的准固态锌离子电池和电池模块均具有优异的性能和实用性。这项工作将为下一代自供电系统的材料设计和器件组装提供一个有前景的研究方向。
