Abstract
En 中文
As high-energy-density solid-state cells approach maturity, battery management systems must be developed to maximize the performance of these cells by monitoring and/or controlling their mechanical stress. This paper describes the design, testing, and control of a lab-scale solid-state battery cell testing system. Solid-state lithium-sulfur cells are characterized under constant volume and constant stress conditions. The testing system also uses axial displacement feedback for mixed volume/stress control and dynamic switching between control modes as a function of state-of-charge and/or charge/discharge conditions.
