This work presents the first application of three-dimensional digital image correlation for real-time displacement and strain analysis of a pouch type lithium-ion battery. During the electrochemical charge discharge processes, displacements in the x-, y- and z-directions vary at different states-ofcharge (SOCs) attributed to the expansion and the contraction of the interior structure. The zdisplacement is observed to develop and concentrate at the vicinity of the openings of the jelly-roll structure. By resolving the displacement components, the progression and distribution of the surface strains, including principal and von-Mises strains, are computed in the charge discharge processes. It is shown that the dominant strains are up to 0.12% in the rolling direction of the jelly-roll structure and distribute uniformly on the x y plane over the surface. (C) 2014 Elsevier B.V.
