FINE CARBON DISPERSION LIQUID AND METHOD OF PRODUCING THE SAME, AND ELECTRODE PASTE AND ELECTRODE FOR LITHIUM ION BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fine carbon fiber dispersion liquid in which fine carbon fibers are dispersed in a dispersion medium at high concentration and uniformly.SOLUTION: A fine carbon fiber dispersion liquid comprises fine carbon fibers having an average diameter of 5-20 nm and a DBP oil absorption of 250-360 ml/100 g, a dispersion medium, and a dispersant. A content of the fine carbon fibers is 0.1-20wt%, a rotational viscosity of the fine carbon fiber dispersion liquid is 50-500 mPa s, and the dispersant is polyvinyl pyrrolidone.SELECTED DRAWING: None
