- Abstract
- In order to investigate the role of iron additive in the Ni3S2 electrode, the Ni3S2 electrode was prepared by addition of iron. The discharge properties of Na/Ni3S2 cells using 1 M NaCF3SO3 in tetra(ethylene glycol) dimethyl ether liquid electrolyte were investigated at room temperature. The Na/Ni3S2 cell had an initial discharge capacity of 400 mAh g(-1) with a plateau potential at 0.84 V versus Na/Na+. The discharge capacity decreased to 255 mAh g(-1) after 15 cycles. Iron additive in Ni3S2 electrode played a role as a conductive agent and did not form iron sulfide during charging. (c) 2010 Elsevier B.V. All rights reserved.
