Die Eignung einiger Übergangsmetallhalogenide als Kathodenmaterialien / The Suitability of Some Transition Metal Halides as Cathode Materials

Some transition metal halides are tested for their suitability as cathode materials in secondary high energy batteries. The solubilities of the silver halides are determined colorimetrically. Furthermore the generation of halide complexes of silver and copper halides in different electrolytes is tested by cyclic voltammetry. It is shown, that with silver and copper halides in different electrolytes, even in a solution of 1 ᴍ LiAlCl in PC halide complexes are formed, which rapidly diffuse from the working electrode. The generated chloro complexes were determined by potentiometric titrations as AgCl , CuCl and CuCl . The use of other transition metal halides is also considered.
