High-density cathode structure of independently acting Prussian-blue-analog nanoparticles: a high-power Zn–Na-ion battery discharging ∼200 mA cm⁻² at 1000C

Abstract

High-density RSW cathodes (1.0–1.3 g cm−3) are prepared by using independently water-dispersible nanoparticles with carbon nanotubes and output high-power 198 mA cm−2/246 mW cm−2 by full-discharging the theoretical capacity at 1000C (66 A g−1).
