On the stress characteristics of graphite anode in commercial pouch lithium-ion battery

► The stress of graphite anode in pouch cell is characterized. ► Compressive stress inhomogeneously distribute in graphite anode. ► Stress generates and accumulates in the early stage of cycling process. ► Stress of graphite anode is directly related to cell thickness swelling. ► Stress causes fast capacity fading during cycling process.
