Abstract

Carbon matrix metal organic frameworks (MOFs) hybrid is often used as electrode materials for lithium ion batteries (LIBs). Herein, we report three dimensional (3D) puffed rice inspired porous carbon (3DPRC) supported Co-MOFs derived composite by facile method. Co/C nanoparticles are uniformly dispersed on porous carbon sheets surface, forming unique 3D structures. As anode of LIBs, the prepared Co/C-3DPRC electrode shows excellent electrochemical properties when compared with the pristine Co/C electrode. With capacity of 430 mAh g^-1 at 1C and 300 mAh g^-1 at 10C is obtained in the composite electrode, respectively. The excellent properties can attribute to the Co/C-3DPRC interconnected porous framework with a high electrical conductivity and large surface area. Our developed design strategies can be extended for fabrication of other heteroatom doped carbon matrix hybrid for environmental energy fields.
