通过在泡沫镍上生长超厚介孔Co 3 O 4纳米片网络，设计了一种用于高面容量锂离子电池负极的新型电极。这种新颖的结构由介孔Co 3 O 4纳米片组成，它们相互连接形成大孔。得益于有利的大/中孔结构以及三维泡沫上合成的Co 3 O 4的大质量负载，这种独特的电极表现出高达4.39 mAh cm− 2的面积容量以及优异的倍率性能和循环稳定性。
An advanced electrode for high areal capacity Li ion battery anode has been designed by growing ultra thick mesoporous Co3O4nanosheet networks on Ni foam. This noval architecture consists of mesoporous Co3O4nanosheets, which are interconnected with each other to form macropores. Benefiting from the favorable macro/meso-porous structures as well as the large mass loading of the synthesized Co3O4on three dimensional foam, this unique electrode exhibits an areal capacity as high as 4.39 mAh cm−2and excellent rate capability and cycling stability.
