  • Structural micro-porous carbon anode for rechargeable lithium ion batteries
    Patent number: 5510212
    Abstract: A secondary battery having a rechargeable lithium-containing anode, a cathode, and a separator positioned between the cathode and anode with an organic electrolyte solution absorbed therein is provided. The anode comprises three-dimensional microporous carbon structures synthesized by the controlled pyrolysis of gel derived polymer foam precursors. The gradual heating process in the carbonization of pretreated foam precursors stabilizes the pore structures in the pretreated foam.
