Abstract

High power capability of the hybrid charge storage device Na-ion capacitor (NIC) is fabricated using battery type TiS₂ as an insertion host with the double layer forming activated carbon (AC) as supercapacitor component. Earlier, it is presumed that Na/TiS₂ system is considered as impractical energy storage system. TiS₂ single crystals are synthesized and exhibit the reversible insertion of ~0.62 mol. Na. AC/TiS₂ assembly is delivering the maximum energy density of ~38 Wh kg⁻¹. One of the important aspects of this NIC is high power capability, which outperformed its analogue Li-ion capacitor fabricated under similar circumstances.
