A rechargeable zinc-manganese battery and a preparation method thereof

The invention provides a rechargeable zinc-manganese battery and a preparation method thereof. A positive electrode adopts a linear alpha-MnO2 material to replace a traditional amorphous manganese dioxide material, and the linear alpha-MnO2 material has a uniform structure. The large tunnels and vacancies in MnO2 increase the contact between the active material and the electrode, reduce the internal resistance of the battery, and improve the diffusivity of protons. The larger aspect ratio of MnO2 can make the preferred orientation degree of the material higher, thus improving the rate performance of the battery. Stable structure, not easy to collapse, the activity can be maintained at a high level, the decay rate is slow, more conducive to the battery cycle performance. In accordance withthat present invention, the preparation method of the alpha-MnO2 material is simple and feasible, the experimental reproducibility is good, the raw materials used are cheap and easy to obtain, the linear alpha-MnO2 material has a uniform structure, large aspect ratio, and stable structure, and is not easy to collapse and slow in attenuation rate.

The invention discloses a dehydrocarbon process suitable for high-hydrocarbon-rich carbon dioxide gas, and relates to the field of carbon dioxide dehydrocarbon purification. The pretreated carbon dioxide-rich raw material gas is divided into two streams through an improved polyimide membrane group. One is feed gas with hydrocarbon content less than 0.02%, and the other is feed gas rich in hydrocarbons. The flow ratio of the two gases is about 1:1. By this method, the gas flow rate that needs to be heated up is halved, the power of the heater is halved, and the energy consumption is reduced by 50%. The other stream containing trace hydrocarbons directly enters the next process. Since the hydrocarbon content is very small, It can be directly liquefied into industrial-grade liquid carbon dioxide, or slightly purified as food-grade liquid carbon dioxide.
