Rechargeable lithium-ion batteries (LIBs) have been attractive as energy storage systems for portable electronic devices and electric vehicles (EVs) because of their high power densities, low cost, and long cycle life. However, there have been still considerable demands for enhancing reversible capacities, cycling stabilities, and rate capabilities. Recently, nickel oxide (NiO) has been attractive as one of the promising anode materials for LIBs because of its high theoretical capacity (about 718 mA h g-1), low cost, and non-toxicity. Nevertheless, NiO suffers from poor rate performance and cycling stability because of the low electronic conductivity and large volume changes during the prolonged cycles. In this work, NiO-embedded carbon sheets (NiO/C) were synthesized through the polymerization reactions of citric acid and ethylene glycol with NaCl as a hard template and Ni precursors. Compared with pristine NiO, the NiO/C composite exhibited the enhanced reversible capacity of about 988.2 mA h g-1 after 50 cycles at 0.1 C and 0.01-3.0 V.
