AB  - Na-ion capacitors (NICs) and Na-based dual-ion batteries (Na-DIBs) have been 
      considered to be promising alternatives to traditional lithium-ion batteries 
      (LIBs) because of the abundance and low cost of the Na-ion, but their energy 
      density, power density and life cycle are limited. Herein, dual-vacancy 
      (including K(+) and F(-) vacancies) perovskite fluoride K(0.86) MnF(2.69) 
      @reduced graphene oxide (rGO; recorded as Mn-G) as anode for NICs and Na-DIBs has 
      been developed. The special conversion/intercalation dual Na-ion energy storage 
      mechanism and pseudocapacitive dynamics are analyzed in detail. The Mn-G//AC NICs 
      and Mn-G//KS6 Na-DIBs delivered a maximum energy density of 92.7 and 
      187.6 W h kg(-1) , a maximum power density of 20.2 and 21.12 kW kg(-1) , and long 
      cycle performance of 61.3 and 68.4 % after 1000 cycles at 5 A g(-1) , 
      respectively. Moreover, Mn-G//AC NICs and Mn-G//KS6 Na-DIBs can work well over a 
      wide range of temperatures (-20 to 40  degrees C). These results make it competitive in 
      Na-ion storage applications with high energy/power density over a wide 
      temperature range.
