In this paper, a work mechanism based on Newton's cradle model for secondary battery is proposed. Zn vertical bar CH3COOLi +Zn(CH3COO)(2)vertical bar LiMn2O4 binary ion battery is a typical Newton's cradle system. Its work process is discussed in detail by cyclic voltammetry (CV). inductively coupled plasma-atomic emission spectrometry (ICP-AES), scanning electron microscope (SEM) and X-ray diffraction (XRD). The charge-discharge curves and cycling calendar life as well as current rate performance indicate that the work mechanism based on Newton's cradle model operates well, the sustainable current rate larger than 20C suggests that this system can offer a considerable high power.
