  • Patent number: 11600822
    Abstract: A cathode material and a fabricating method thereof, and a lithium-ion battery are described. The cathode material is a 1D metal-organic coordination polymer of [CuL(Py)2]n, and its structure is formed by interlinking organic ligands (L) and metals (Cu). The cathode material can use redox active sites on both the metal and organic ligand to carry out multi-electron transfer. A C?N bond contained in L together with a benzene ring of L in an adjacent polymer chain form a weak interaction of C?N . . . ?. In addition, a Py of adjacent polymer chains also have an interaction of ? . . . ?. Therefore, [CuL(Py)2]n chains are closely interlaced and packed, but there is still enough regular space for lithium ions to enter and exit quickly, so it can be charged and discharged rapidly and exhibits high power density.
