    • A battery electrode paste composition containing modified maleimide(s) is provided, which has an electrode active material, a conductive additive, a binder and modified maleimide(s) as dispersant. The modified maleimide as the dispersant in the battery electrode paste composition has dendrimer-like hyperbranched structures, which can form a stable complex with the electrode active material. Therefore, owing to the excellent compatibility of the modified maleimide with the solvent in the electrode paste, the storage stability of the paste is increased. Furthermore, through formation of stable bonding between the modified maleimide and the current-collecting metal substrate, the adhesive force between the electrode film and the current-collecting metal substrate is enhanced and the cycling life of the battery product is extended.
    • 提供含有改性马来酰亚胺的电池电极糊剂组合物,其具有电极活性材料,导电添加剂,粘合剂和改性马来酰亚胺作为分散剂。 在电池电极糊料组合物中作为分散剂的改性马来酰亚胺具有树枝状大分子超支化结构,其可以与电极活性材料形成稳定的络合物。 因此,由于改性马来酰亚胺与电极糊中的溶剂的相溶性优异,因此糊料的保存稳定性提高。 此外,通过形成改性马来酰亚胺和集电金属基材之间的稳定结合,电极膜和集电金属基板之间的粘合力增强,电池产品的循环寿命延长。
