Structure and Interfaces of Advanced Battery Electrode and Electrolytes
EMSL Project ID
61060
Abstract
The research undertaken as part of this project will yield fundamental results that will inform electrolyte design and optimization for advanced battery systems, and enhance development of existing, conventional battery chemistries to extend their usage profile. It is supported through the DOE Office of Electricity Cost-Competitive Energy Storage Program. The core theme is the exploration of the structure-property relationships that link the local interactions, composition, and dynamics of the electrolytes with their bulk transport and interface properties, with an emphasis on systems that could potentially furnish much more inexpensive grid-scale energy storage. In the Pb-acid system, this takes the form of correlating changes in the solution structure with concentration, temperature, and the presence of additives, coupled with post-mortem studies on commercial electrode plates as well as the chemistry and the structural evolution of active electrode surfaces during charging and discharging. With all cases, the combination of X-ray diffraction and inductively coupled plasma mass spectrometry (ICP-MS) capabilities available through EMSL will be decisive in deriving key insights necessary to aid development of these battery technologies.
