Research and Development of Long Life Lead Carbon Battery for Energy Storage

Abstract

This thesis is a summarization of a lead acid battery research and development work. The first four sections present briefly the lead acid battery (LAB) history, battery structure, fundamental theory, application in energy storage and a literature of latest research on carbon as an additive in advance lead acid battery system. In the following main sections, the detailed research design, procedure, lab experiments, experiment result are discussed. The research goal is to highly improve the deep cycle life and rate performance of the conventional lead acid battery in a cost-efficient way. According to latest research using carbon material as additive in the negative electrode paste could be the direction. The practical way to experiment this Lead Carbon Battery (LCB) idea is presented. Then the experiment procedures and test methods, like negative paste preparation, quality control, single cell assembly and performance testing, are all detailed in text, tables and/or pictures. There after an optimized experiment procedure and test protocols is concluded. This would be the guidance to the high-performance lead acid battery industrial manufacturing. Finally, a comparison of LCB and conventional LAB in terms of 100% DOD (depth of discharge) cycle life and specific energy cost is discussed.
