    Sammanfattning : Lithium-ion batteries are commonly used for energy storage systems, and temperature is one key impact factor on the cell performance and lifetime. In literature, the focus has been on the ambient temperature of the test condition, and there is little discussion about how the temperature swing during cycling affects the battery lifetime. LÄS MER
