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.

normalLiBfalse(CH3)4 is an example of a large class of boron complex anion salts which are very soluble and highly conductive in dioxolane. Solutions of normalLiBfalse(CH3)4 have been investigated as electrolytes in normalLi‐TiS2 cells. At room temperature such cells have been operated as rechargeable energy storage devices which are capable of continuous discharge (5 mA/cm2) and charge (1.25 mA/cm2) cycling. While solutions of normalLiBfalse(CH3)4‐normaldioxolane appear stable over long periods, contact with TiS2 results in anion oxidation with concomitant formation of LixTiS2 false(x<1false) . The oxidation products are gases whose apparent rate of generation is proportional to the concentrations of solute and TiS2 . The product distribution depends on whether normalLiBfalse(CH3)4‐normaldioxolane solution contacts TiS2 alone, or in a normalLi‐TiS2 cell. The electrolyte‐cathode reaction is thought to involve transient methyl radicals which are formed during a concerted process involving anion oxidation and TiS2 lithiation.

Li‐TiS2‐Zellen mit Dioxolan‐Lösungen von LiBMe4 als Elektrolyt werden bei Raumtemp. als wiederaufladbare Energiespeichervorrich.tungen, die kontinuierlich entladen (5 mA cm ′2) und geladen (1.25 mA cm ü) werden können, betrieben.

Die schlechte Reversibilität einer Li/NbSe3‐Zelle läßt sich durch Verwendung von Dioxolan als Lösungsmittel für den Elektrolyten (LiClO4) entschieden verbessern.
