Abstract
A hyper-branched polymer dispersant represented by, for example, formula (I) has high adhesion properties to a current collector substrate and therefore enables the formation of an electrically conductive bonding layer having high carbon nanotube concentration. When a composite current collector for an energy storage device electrode which is equipped with the electrically conductive bonding layer is used, it becomes possible to produce an energy storage device from which an electrical current can be extracted without causing the decrease in a voltage particularly in use applications that require a large electrical current instantaneously, such as electrical automotive applications, and which has a long cycle life.
