A facile synthesis of highly porous CdSnO3 nanoparticles and their enhanced performance in lithium-ion batteries

CdSnO3 materials have been extensively studied as gas-sensing materials. However, there are few reports on the synthesis and use of porous CdSnO3 nanostructures for energy storage. Herein, we report highly porous CdSnO3 nanoparticles prepared using citric acid with sizes in the range of similar to 7.8 nm to 28.7 nm and the application of these nanoparticles as an anode material for rechargeable Li-ion batteries ( LIBs). Electrochemical measurements showed that the highly porous CdSnO3 nanoparticles delivered a high reversible capacity of similar to 515 mA h g(-1) for up to 40 cycles at a current rate of 70 mA g(-1). Even at a high rate of 150 mA g(-1), the porous CdSnO3 could still deliver a capacity of 506 mA h g(-1). It is observed that the electrochemical performance of the highly porous CdSnO3 nanoparticles is much better than that (similar to 370 mA h g(-1) for up to 40 cycles) of a counterpart obtained without citric acid, which also demonstrates the capacity enhancement and high rate capacity.
