- 요약Small changes to the makeup of a battery's electrode will lead to measurable changes in collected current and voltage data. Ongoing efforts seek to optimize positive electrode materials, their interfaces with the electrolyte, and the overall structure of the electrode itself. Interpreting the signals, however, is not entirely straightforward. Often, voltage and current data can be misinterpreted, leading to poorly informed and inefficient optimization feedback loops.This thesis demonstrates how careful interpretation of voltage and current signals, with understanding built from thermodynamic and kinetic fundamentals, enables more accurate assessment of battery performance. We will step through three examples that tackle increasingly complex levels of design optimization: positive electrode material synthesis, interface modification, and electrode architecture. We will focus on layered oxide positive electrode materials, such as Li(NixMnyCoz)O2(NMC) or Li-, Mn-Rich layered oxides (LMR), with Li metal counter electrodes. In Chapter 3 we will reveal, through careful measurement of the voltage, that changes to positive electrode synthesis methods do not engender new redox reactions, but a step-change in kinetic limitations. In Chapter 4, we will demonstrate the impact of particle-to-particle heterogeneity, and uncover the mechanism by which performance is improved through an interfacial modification. Finally, in Chapter 5, we will use the understanding built in Chapters 3 & 4 to uncover loss mechanisms incurred when electrode architecture transitions from liquid- to solid-electrolytes. These findings will then help us understand how interface modifications and heterogeneity limit the performance of solid-state batteries.
