Tuning and probing initial stages of lithium deposition for lithium metal battery anodes
Abstract/Contents
- Abstract
- Rechargeable lithium-ion batteries have become ubiquitous energy storage devices in society, functioning as power sources for electronics ranging from personal devices to electric transportation to grid-scale energy storage. However, in order to meet fast-growing demands for increased range of electric vehicles and longer times between charging of devices, higher energy density batteries with next-generation chemistries need to be developed. High capacity electrode materials like lithium metal are ideal candidates for advanced batteries, but suffer various problems which remain unsolved. Much research has been dedicated to elucidating and mitigating the safety and performance problems of lithium metal research, but bringing practical lithium batteries to market has still been impossible. In Chapter 1, the background and problems of lithium metal anodes are introduced, along with some discussion about current strategies for enabling their use. In Chapter 2, initial studies on the nucleation of lithium metal during electrodeposition are discussed and put into context the importance of the initial states of lithium metal growth. Chapters 3 and 4 introduce some examples of soft polymeric protective coatings developed to prevent performance decay of lithium electrodes, in addition to studies of standard polymers and determination of polymer properties which are critical to functional coatings. Chapter 5 introduces microelectrodes as a tool for high rate studies of lithium metal kinetics during deposition and stripping, and demonstrate the growth of highly faceted lithium metal particles during these high rate deposition experiments. Finally, lithium metal is put into context for future use as a practical anode material, and considerations related to the manufacturing and production of lithium metal-containing cells are discussed. Ultimately, it will be the combination of both advances in battery technology through research like what is presented here and the advent of new manufacturing techniques compatible with lithium metal that will enable a new paradigm in lithium-ion anode technology.
