MOFS-DERIVED CARBON AEROGELS, PREPARATION METHOD THEREOF AND APPLICATION THEREOF IN LITHIUM ION BATTERY

The invention relates to the technical field of lithium-ion batteries, and in particular to an MOFs-derived carbon aerogel, a preparation method thereof and an application thereof in lithium-ion batteries. The method includes the following steps: firstly, preparing [Cd(tppa)zC|2], wherein [Cd(tppa)zC|2] is a macroporous metal-organic framework material (MOFs), and carbonizing by using it; the obtained MOFs-derived carbon aerogel has the characteristics of porosity and light weight, so that lithium-ions may have more lithium storage space in the lithium intercalation process, and the performance of the material remains stable after repeated cycles. The MOFs-derived carbon aerogel of the invention is used as the cathode active material of lithium-ion batteries, and has excellent electrochemical performance: it has not only ultra-long cycle capacity and extremely high rate performance, and but also high reversible capacity at a small current density; therefore, it is hopeful to replace graphite and become the commercialized cathode material of a new generation of lithium-ion batteries.
