Rechargeable lithium-ion batteries (LIBs) are essential for future portable electronics, electric vehicles, and in the storage of renewable energy. Thus, the development of electrode materials and new reaction mechanisms for the production of LIBs with improved energy density and power capability is necessary.

Xianluo Hu, Yunhui Huang, and co-workers at the Huazhong University of Science and Technology, China, have developed a microwave-assisted in situ synthesis of nanocomposites that are comprised of Zn₂GeO₄ nanorods assembled within 3D interconnecting frameworks of conducting N-doped graphene sheets (pictured). The Zn₂GeO₄/N-doped graphene nanohybrid exhibits highly reversible capacity, excellent cyclability, and superior rate capability as an anode material in LIBs.

This method could become an effective strategy for the fabrication of other high-performance electrode materials and functional devices.
