    Recently, the research team of Wu Zhongshuai of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences used low-cost and large-scale screen printing technology to prepare highly flexible, high-safety and long-life secondary aqueous planarized zinc-manganese miniature batteries
    .
    This is a method for large-scale preparation of planarized zinc-manganese miniature batteries with great industrial application prospects, and also provides new ideas
    for the development of other planarized flexible energy storage devices.

    The team developed a low-cost, simple, efficient, and large-scale screen printing technology, and successfully prepared a new concept of aqueous planarized zinc-manganese miniature battery
    with good mechanical flexibility, high safety and long life.
    Researchers first used manganese dioxide, zinc powder and graphene as functional materials, and configured the positive and negative electrodes of zinc-manganese batteries and graphene current collector thixotropic inks respectively; Then, the multi-step screen printing method was used to realize the simple and low-cost large-scale preparation
    of planarized zinc-manganese micro-batteries.
    The zinc-manganese battery not only has the characteristics of environmental friendliness and high safety, but also shows a long working life, and can maintain a specific capacity of 83.
    9% under a current density of 5C for 1300 cycles, while having good mechanical flexibility and performance consistency
    .
    In addition, the diversity of printing substrates can meet the needs
    of different application scenarios.
