a GCD curves and (b) corresponding o-SXRD patterns of typical characteristic Bragg peaks in the initial two cycles. c GCD curves and (d) corresponding o-SXRD patterns of typical characteristic Bragg peaks in the two cycles after cycling. e Quantized lattice expansion during the measured cycles. f Schematic of the pillar effects of copper carrier redox during the intercalation process. g TEM observation, (h) HAADF image, and the corresponding (i), Cu, (j), S, (k), V elemental mapping of full-discharged product. l, HRTEM image and SAED pattern of full-discharged product.
