Perovskite fluoride NaNiF3 with hollow micron sphere structure as anode for Li-ion hybrid capacitors
文献摘要：
Lithium-ion hybrid capacitors(LIHCs)are gaining more attention and applications because they break the performance limitations of supercapacitors(SCs)and lithium-ion batteries(LIBs).However,the difference of energy storage mechanism between anode and cathode is a problem that must be faced by Li-ion hybrid capacitors.The selection of suitable anode and cathode materials is one of the effective ways to solve this problem.Here,we synthesized hollow spherical perovskite fluoride NaNiF3 by a simple and safe method.The specific capacity of NaNiF3 is 142 mAh·g-1 at 0.1 A·g-1 for 1000 cycles.The mechanism in the cycling of NaNiF3 electrodes was investigated using ex situ X-ray photoelectron spec-troscopy(XPS),which is typical of the conversion reaction.Meanwhile,the NaNiF3//activated carbon(AC)Li-ion hybrid capacitor assembled and showed better energy density(69 Wh·kg-1)and power density(5699 W·kg-1).Its capacity retention after long cycling was 79％.The use of NaNiF3 expands the choice of electrode materials for LIHCs and extends their practical applications.
