The research team of Wu Zhongshuai, Dalian Institute of Chemical Physics, Chinese Academy of Sciences used low-cost, large-scale screen printing technology to prepare secondary aqueous planar zinc-manganese micro-batteries with good commercial application prospects, high flexibility, high safety and long life. Published in the National Science Review. The development of a new generation of miniaturized and wearable electronic products has greatly stimulated people's urgent need for matching new concepts, high-security, long-life micro-energy storage devices, especially planar micro batteries. The planarized mini battery has the characteristics of high integration and integration, which overcomes the shortcomings of the traditional sandwich configuration battery, such as large size, poor mechanical flexibility, and easy separation of the interface under bending. It is a new type of wearable electronic device power source with great development prospects. . The team developed a low-cost, simple, efficient, and large-scale screen printing technology, and successfully prepared a new concept water-based planar zinc-manganese microbattery with good mechanical flexibility, high safety, and long life. They first used manganese dioxide, zinc powder, and graphene as functional materials to configure the positive and negative electrodes of the zinc-manganese battery and graphene current collector thixotropic ink, and then used a multi-step screen printing method to achieve planarized zinc-manganese. Low-cost, large-scale production of miniature batteries. The new zinc-manganese battery not only has the characteristics of environmental friendliness and high safety, but also exhibits a long working life. In addition, the diversity of printed substrates can also meet the needs of different application scenarios.
