Abstract

Herein, a unique hierarchical structure of interconnected microspheres constructed by regular lithium titanate (Li4Ti5O12) nanosheets has been prepared via a facile and smart approach. When evaluated as anode materials for lithium-ion batteries (LIBs), the as-prepared Li4Ti5O12 shows outstanding lithium storage performance, delivering a high reversible specific capacity of 161.9 and 141.1mAhg−1 after 300 and 1200 cycles at 20 and 200mAg−1, respectively. This work may open up a broader vision into developing advanced Li4Ti5O12 anode materials for LIBs.
