TechPak Categories Carbon Negative Electrodes for Lithium Secondary Batteries Carbon anodes based on our carbon materials can be used for lithium ion secondary batteries, providing them with high energy densities and excellent cycle characteristics and making them capable of large-current charge and discharge. Carbon materials are highly crystalline. Although their theoretical energy density is high (372 mAh/g), it is difficult to use them for charge and discharge at large currents because of their low internal impedance. Our carbon anodes have solved this problem. Our carbon anode technology simultaneously improves electron conduction between carbon materials and filling density of the carbon material particles. This produces a high energy density anode capable of large-current charge and discharge. Beyond that, our technology suppresses swelling and shrinkage of the anode associated with changes in the crystalline structure of the carbon materials during the charge and discharge processes. The result is excellent cycle characteristics. Technological characteristics of the carbon anodes based on our carbon materials lie in the mixture of two or more carbon materials whose spacing of lattice in the C-axis direction (d002) is 3.40 Å. This technology greatly improves the characteristics of lithium ion secondary batteries. A US patent has been issued for this technology. Interested?
