A type of bimetallic ZnTe-CoTe2 heterostructure was synthesized adopting template-assisted method which was supported on N-doped carbon framework (NC) to serve as sulfur host for lithium sulfur batteries (LSBs). The NC structure not only could build efficient conductive channels for fast ion/electron transport, but also inhibit the polysulfides shuttling via multiple spatial confinement. Besides, the construction of ZnTe-CoTe2 heterogeneous interface weakened the nucleation/decomposition barrier of Li2S and promoted the bidirectional conversion of sulfur. Benefiting from the advantages mentioned above, therefore, the assembled batteries delivered a high initial discharge capacity of 1250 mAh g-1 at 0.2 C and achieved enhanced long cycling performance with an attenuation rate of 0.047% at 1 C after 1000 cycles. Furthermore, even under sulfur loading of 4 mg cm-2 and E/S ratio of 6 μL mg-1, the area capacity could also reach to 3 mAh cm−2.

In this study, urchin and tremella-like NiCo2O4 was synthesised by adopting a facile hydrothermal method using green solvents (water and ethanol). Using different ratios and pure forms of green solvents has a direct impact on materials synthesised. Ethanol based NiCo2O4 (NCO-E) illustrated tremella like microspheres with a specific surface area of 260.8 m2 g−1. The electrochemical performance confirmed that the NCO-E has a maximum specific capacitance of 2271 F g−1 at a current density of 1 A g−1. Further, as-fabricated NCO-E//AC-ASC device delivers a Cs value of 96.6 F g−1 at 1 A g−1 and a cyclic stability of 99.68 % over 5000 cycles. The device exhibited a high energy density of 30.19 Wh kg−1 at a power density of 749.48 W kg−1 and a high power density of 7542.61 W kg−1 at energy density 18.43 Wh kg−1 owing to the working electrode's effective electrochemical usage and excellent ion transfer mechanism.
