FRACTURE IN LITHIUM-ION BATTERIES AND FUEL CELLS

 Hybrid propulsion system has become popular in marine industry due to increasingly strict emission control standards. Hence, as one component in the system, marine batteries become attractive in marine design. Solid Oxide Fuel Cells (SOFCs) and lithium ion battery are the most promising energy storage devices in the electric propulsion system or HPS. Since silicon particles expands around 400% in volume during lithation, the battery electrodes will experience large volumetric change during normal battery cycling. As a result, misdistribution of stress may form inside the battery electrode. Therefore, degradation and delamination may happens in the battery electrode after many cycling process of marine battery.
