Sodium‐titanium disulfide cells have been cycled at ambient temperature in sodium triethyl(N‐pyrrolyl)borate‐dioxolane electrolyte. During primary discharge at 2.5 mA/cm2 two voltage plateaus or steps are seen in plots of cell emf vs. sodium stoichiometry in NaxTiS2 and a limiting cathode composition is reached when x is 0.8. During repeated discharge and recharge cycling the capacity of the higher voltage step is lost while the capacity of the lower voltage step remains essentially constant. A simple prismatic design for sodium organic electrolyte cells is described and characteristic properties of the electrolyte are discussed.

Proton magnetic resonance measurements of the aqueous ZnQ-KOH system have been made. Only a single resonance line is observed, but the position of the line depends on the concentrations of KOH and ZnO. Analysis of the data is consistent with the presence of only one zincate species. A value for the chemical shift of the zincate ion is derived, and also a more precise value for the chemical shift of KOH in water is determined. The significance of the results is discussed.
