SOURCES OF DEGRADATION IN LI-S CELLS
Original language description
Lithium-sulfur batteries have attracted the focus of scientists for more than four decades [1-4]. This type of battery represents a promising system of high theoretical capacity, energy density, low cost and the non-toxicity of sulfur. Yet many challenges facing the Li-S technology exist, either with the materials or with the systems, such as a low utilization of sulfur, poor cycle life, high self-discharge rates and capacity fading [1], [3-5]. The degradation mechanisms in Li-S batteries, that are responsible for low sulfur utilization and capacity fading, are still unclear [3,6,7], since some mechanisms may lead to reversible or irreversible degradation [6]. Dominant sources of degradation are determined through Coulombic efficiency and energy efficiency dependences on the number of cycles and from the temperature evolution within the cell cycling.
