English to French Tech/Engineering Chemistry; Chem Sci/Eng (in a patent) COPPER-DOPED LITHIUM COBALT OXIDE PRECURSOR, POSITIVE ELECTRODE MATERIAL, PREPARATION METHOD AND USE THEREOF

In addition, there are [CuO4] chains in the structure of lithium cuprate, which are arranged in a co top manner and exist in a tetrahedron formed by the oxygen atoms with the Cu atom as the center. Such structure is relatively stable under high voltage, and it can also provide a channel for transferring lithium ions. During the charging and discharging process, lithium ions can enter and exit the [CuO4] structures through the gap therebetween, thereby ensuring the stable structure and the normal charge and discharge of the positive electrode material simultaneously.
