However, the traditional solid\u2010core structure restricts internal ion transport pathways, leading to structural degradation and sluggish reaction kinetics during long\u2010term charge\u2013discharge cycles. Here, a novel hollow core\u2010shell structure composite construction strategy was presented by growing Co\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    nanorods on the surface of Cu\u2010containing ZIF\u20108 precursor derived hollow Cu\u2013ZnO nanoframe via anisotropic chemical etching and in situ metal oxidation processes (Co\n                    <jats:sub>3<\/jats:sub>\n                    \/Cu\u2013ZnO). The hollow core effectively shortens the ion diffusion path and provides sufficient internal space to accommodate volume variation, while the Co\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    nanorod shell contributes high pseudocapacitive activity through the redox reactions of its multivalent cobalt ions (Co\n                    <jats:sup>2+<\/jats:sup>\n                    \/Co\n                    <jats:sup>3+<\/jats:sup>\n                    and Co\n                    <jats:sup>3+<\/jats:sup>\n                    \/Co\n                    <jats:sup>4+<\/jats:sup>\n                    ).
