Homogeneous nano-CeO 2 coated on LiMn 2 O 4 powder has been successfully prepared via a facile solid-state approach. Our work demonstrates that surface modification of LiMn 2 O 4 sintered at 450 °C shows a high initial discharge of 137.7 mAh·g −1 and superior capacity retention with 95.86%, which is...
