Abstract :A reliable supply of energy source is required for aerospace applications. Due to their high specific energy density and low self-discharge, Lithium-ion cells are preferred over other energy sources. Pouch cells have much better energy density compared to metallic cell cases. A pouch cell is developed for launch vehicle and automotive applications. Two aluminum-polymer laminates are heat sealed at 180-1900 C to form the pouch cell. Experimental characterization insert ignore into journalissuearticles values( lap shear, T-peel and tensile); of bonded laminate/films are carried out. UTS of laminate is obtained from lap shear and tensile tests. Fracture energy insert ignore into journalissuearticles values(mode-1); is obtained from T-peel tests and used as an input for the cohesive zone model. Mechanics of pouch cell due to internal pressure insert ignore into journalissuearticles values(abuse condition); is performedKeywords : Aluminum polymer laminates, Burst test, Experiment, Finite element analysis, Pouch cell
