Moderate Temperature Sodium Cells: I . Transition Metal Disulfide Cathodes

Abstract: A moderate temperature, rechargeable Na cell having the configurationnormalLiquid Na/β‐Al2O3/Na+‐normalconducting electrolyte/normalTransition metal disulfideis described. The cell operates at ∼130°C. Three transition metal disulfides, TiS2 , VS2 , and Nb1.1S2 , have been evaluated as cathode materials. A 1M solution of normalNaI in 1,2‐Bis(2‐methoxy‐ethoxy)ethane, (triglyme), served as the electrolyte. The mechanism of discharge in all the three cathode materials involves Na intercalation. Experimental re… Show more

“…The cathodic/anodic peaks at 1.08 / 0.96 V contributed by the layered sodium titanium oxides may overlap with the Na-intercalation/deintercalation processes of VS 2 , limiting their visibility. Consequently, we propose a possible sodium-storage mechanism in the NTO-VS 2 composite electrode at the initial discharge as follows [19,30,35]: …”

“…Aside from its intrinsically metallic behavior, VS 2 monolayer also has a higher theoretical capacity of 466 mA h g -1 for lithium storage and a lower or similar lithium diffusion barrier compared to MoS 2 and graphite, which makes it a highly attractive anode candidate for energy storage [29]. VS 2 was first reported as a cathode with the Na system in the 1980s, and it intercalated up to one Na per VS 2 during first discharge as a cathode [30,31].…”

“…In spite of several early reports on the Na intercalation of layered NaMS 2 (M = transition metal) [14,15], these layered sulfides are conspicuously absent in the battery literature. This absence is understandable considering the history of Li-ion battery development, where layered sulfide electrodes were replaced by layered oxide cathodes and carbon anodes.…”

“…Accordingly, various efforts have been made to offer alternative high specific energy/power batteries operating at reduced temperatures [ 1,2,3 ]. However, since electrode kinetics and mass transport processes in batteries are thermally activated, lower temperature systems often present a compromise between lower power output, and enhanced reliability, safety, and economic factors.…”
