Abstract

The invention discloses application of semi-porphyazine and transition metal complex thereof serving as lithium / thionyl chloride battery catalyst. Discharging performance of batteries is obviously improved, discharging time is prolonged, and discharging voltage is improved by adding the semi-porphyazine and transition metal complex of the semi-porphyazine.

Description

technical field [0001] The invention relates to the application of semi-porphyrazine and a transition metal complex thereof as a lithium / thionyl chloride battery catalyst, belonging to the technical field of batteries. Background technique [0002] In the past few decades, there have been many studies on how to improve the performance of lithium / thionyl chloride batteries. Metal phthalocyanine complexes have been reported as catalysts for such batteries, and some progress has been made. Studies have shown that transition metal phthalocyanine complexes have a good catalytic effect on lithium / thionyl chloride batteries. [0003] Hemiporphyrazines (Hemiporphyrazines, H 2 hp) has a nitrogen-containing macrocyclic structure similar to phthalocyanine, and has a large conjugated system with 20-π delocalized electrons. As far as the inventor knows, there is no literature report on the application of semi-porphyrazine and its metal complexes as catalysts in lithium / thionyl chloride...
