New materials systems for aqueous batteries
Abstract/Contents
- Abstract
- Existing battery technologies do not offer the cycle life, power, energy efficiency, or low cost needed for widespread adoption on the electric power grid. In the first part of this thesis, the development of aqueous lithium ion batteries is discussed. In the second part of this thesis, the use of Prussian Blue analogues as battery electrodes in aqueous potassium ion and sodium ion cells is presented. These materials have extremely fast kinetics and long cycle life when operated as battery electrodes in aqueous electrolytes. The effects of insertion species and electrode composition on the performance of Prussian Blue analogue electrodes were characterized in aqueous half-cells. Cycle lives of up to 40,000 cycles and high rate capability (over 80C) were observed for these electrode materials. Full cells were built using a copper hexacyanoferrate cathode, an activated carbon/conductive polymer anode, and an aqueous potassium ion electrolyte. These batteries batteries show promise for stationary storage applications including those on the electric grid.
