Synergistic effects of novel battery manufacturing processes for lead/acid batteries: Part II: Mechanistic studies

摘要: The mechanistic aspects of the beneficial effects different manufacturing processes on performance lead/acid batteries have been studied using electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD) and scanning electron microscopy (SEM). implications grid etching, active material compression spiking with conductive additives, along various combinations these processes, PAM positive electrode corrosion layer shown that a combination additives reduces PbSO4 content both (PAM) layer, leading to an enhancement in battery performance. Furthermore, impact most promising process kinetics occurring LAB, as EIS, has charge transfer resistance control cells fully discharged state increases cycling, while treated behaved like near-perfect capacitor, yielding negligible resistance. EIS additive spiked compressed is accelerated respect cells.
