Abstract

The present invention relates to the technical field of lithium-ion batteries, and provides a MOFs-derived carbon aerogel, a manufacturing method thereof, and an application to lithium-ion batteries. The present invention first manufactures [Cd(tppa)2Cl2], which is a kind of macroporous metal-organic framework material (MOFs). When carbonization is carried out using this, the obtained MOFs-derived carbon aerogel has the characteristics of being porous and lightweight, and can have more lithium storage space in the process of lithium ions desorbing lithium. The performance of the material remains stable even after many cycles. The MOFs-derived carbon aerogel of the present invention is used as a negative electrode active material of a lithium-ion battery, has extremely excellent electrochemical performance, not only has ultra-long cycle ability and extremely high rate performance, but also has a high reversible capacity at a small current density, and is promising as a negative electrode material for the commercialization of next-generation lithium-ion batteries to replace graphite.
