Significantly enhanced electrochemical performance of lithium titanate anode for lithium ion battery by the hybrid of nitrogen and sulfur co-doped graphene quantum dots Original Research Article Electrochimica Acta, Available online 6 August 2015, Pages Li Ruiyi, Jiang Yuanyuan, Zhou Xiaoyan, Li Zaijun, Gu Zhiguo, Wang Guangli, Liu Junkang
Graphical abstract

The study reported a facile synthesis of Li4Ti5O12/nitrogen and sulfur co-doped graphene quantum dots (LTO/N,S-GQDs). The unique architecture and the introduction of N,S-GQDs create both ultrafast electron transfer and electrolyte transport. The as-prepared LTO/N,S-GQDs anode provides prominent advantage of specific capacity, high-rate performance and cycle stability. | Is single layer graphene a promising anode for sodium-ion batteries?
