Abstract： |
The invention discloses an active carbon micro-sphere-packing metal compound cathode material and making method in the chemical engineering and source material technological domain, which is characterized by the following: blending metal grain in the active carbon micro-sphere; making the metal as Li-reserving active metal at 30-80 percent; adopting phenol resin, metal or oxidation as priority; proceeding high-temperature disposal to carbonation reduction through solidifying inversed-colloidal group emulsion. The invention possesses higher first charging specific capacity and second charging and discharging circulated capacitance, which displays excellent circulating property. |
