被撤回的出版物: Hollow amorphous NaFePO4 nanospheres as a high-capacity and high-rate cathode for sodium-ion batteries (Publication with Expression of Concern. See vol. 6, pg. 13979, 2018) (Retracted article. See vol. 7, pg. 20441, 2019)

Hollow amorphous NaFePO4 nanospheres were prepared on a large scale by a simple in situ hard template process, wherein the hollow nanospheres exhibited a high storage capacity and high rate as a cathode material for sodium-ion batteries.
