    • A composition for a battery containing an electroconductive assistant improves battery performance of a battery produced using this composition as a result of achieving dispersion stabilization without inhibiting electroconductivity of the electroconductive assistant. The invention provides a composition for a battery comprising at least one type of dispersant selected from an organic pigment derivative having an acidic functional group(s) or a triazine derivative having an acidic functional group(s), a carbon material as an electroconductive assistant, and as necessary, a solvent, a binder and a positive electrode active substance or negative electrode active substance; and also provides a lithium secondary battery comprising a positive electrode having a positive electrode composite layer on a current collector, a negative electrode having a negative electrode composite layer on a current collector, an electrolyte containing lithium, and as necessary, an electrode foundation layer, wherein the positive electrode composite layer, the negative electrode composite layer or the electrode foundation layer is formed using the composition for a battery described above.
    • 含有导电助剂的电池用组合物通过实现分散稳定化而不阻碍导电助剂的导电性,提高使用该组合物制造的电池的电池性能。 本发明提供一种电池组合物,其包含选自具有酸性官能团的有机颜料衍生物或具有酸性官能团的三嗪衍生物,作为导电助剂的碳材料的至少一种分散剂, 根据需要,可以使用溶剂,粘合剂和正极活性物质或负极活性物质; 并且还提供一种锂二次电池,其包括在集电体上具有正极复合层的正极,在集电体上具有负极复合层的负极,含有锂的电解液,根据需要,包括电极基底层, 其中使用上述电池组合物形成正极复合层,负极复合层或电极基底层。
