CT cross-sections in (a–e) x/y-plane and (f–j) x/z-plane; (a,f) jelly roll in a pristine state before discharge in CaCl2 solution; (b–e) light to severe deformation of the jelly roll due to storage in CaCl2 solution; (g) no dissolution of the active material for 5 min storage; (h–j) light to the severe dissolution of the active material for 10 h, 48 h, and 1 week storage time in CaCl2; the deformation of the jelly facilitates the penetration of the CaCl2 and leads to the faster dissolution of the active material.
