Abstract: |
The invention discloses a preparing technology of high-energy Li-marcasite battery material, which comprises the following steps: covering conductivity and stable metal oxide on the surface of marcasite with composite conductive; setting the percentage of marcasite at 82-94 percent, conductive percentage at 4-10 percent and metal oxide percentage at 2-8 percent. The method reduces grain size of natural marcasite material through wetting ball grinding technology, which prepares the needed anode material. |
