| Abstract |
Serious environmental pollution and rapid depletion of fossil fuel reserves have facilitated the development of alternative energy conversion/storage systems in the past few decades. Lithium-ion batteries (LIBs) have recently been the most attractive means to store electric energy because of the low environmental impact, high energy density, and long cycle life. Nevertheless, the conventional LIBs using graphite as an anode have limitations to meet the increasing demands for high performance batteries due to its low theoretical capacity (about 372 mAh g-1) and the lithium dendrites formation on graphite surface. NiO has been considered as an alternative anode material with its high theoretical capacity (about 718 mAh g-1), nontoxicity, and low cost. However, NiO suffers from severe volume changes, rapid fading due to particle aggregations, and poor electronic conductivity during long-term cycles. As an effort to solve these issues, NiO-embedded carbon sheets (NiOC) were synthesized in this work. The carbon sheets were synthesized by polymerization reactions of citric acid and ethylene glycol with salts (NaCl and KCl) as structural templates. The NiOC composite exhibited the significantly improved cycling performance than bare NiO at 0.1 C rate in the 0.0-3.0 V voltage range. |
