In operando visualization of electrolyte stratification dynamics in lead-acid battery using phase-contrast X-ray imaging.

Abstract

An understanding of electrolyte stratification behaviours in lead-acid battery electrolytes during battery operation is important for optimal operation and design of lead-acid batteries for vehicle applications. In this paper, we present an in operando phase-contrast X-ray imaging technique for quantitatively visualizing electrolyte stratification dynamics that arise in electrolytes during battery operation.
