英文摘要	Co 3 O 4 is a promising high-performance anode for lithium ion batteries (LIBs), but suffers from unsatisfied cyclability originating duo to low electrical conductivity and large volume expansion during charge and discharge process. Herein, we successfully constructed the Co 3 O 4 nanoparticles embedded into graphene nanoscrolls (GNSs) as advanced anode for high-performance LIBs with large capacity and exceptional cyclability. The one-dimensional (1D) Co 3 O 4 3 O 4 nanoparticles, followed by freeze drying and annealing at 400?°C for 2?h in nitrogen atmosphere. Benefiting from the interconnected porous network constructed by 1D Co 3 O 4 3 O 4 during lithiation and delithiation. The resultant Co 3 O 4 ?1 at 0.1?C, outperforming most reported Co 3 O 4 anodes. Moreover, they showed high rate capability of 600 mAh g ?1 at 5?C, and outstanding cycling stability with a high capacity retention of 90% after 500 cycles. Therefore, this developed strategy could be extended as an universal and scalable approach for intergrating various metal oxide materials into GNSs for energy storage and conversion applications.
