Abstract

The invention discloses an Li / SOCl2 nano cobalt phthalocyanine catalyst material for a battery and a preparation method of the Li / SOCl2 nano cobalt phthalocyanine catalyst material, and belongs to the technical field of preparation of Li / SOCl2 catalytic materials for battery electrodes. The bulk solid cobalt phthalocyanine is firstly synthesized through microwave reaction; and then nano cobalt phthalocyanine is prepared by a recrystallization method. The method comprises the steps as follows: the bulk solid cobalt phthalocyanine is firstly dissolved into a concentrated sulfuric acid; a very dilute potassium hydroxide solution is added and quickly stirred for severe neutralization reaction; accelerated nucleation of the cobalt phthalocyanine is relatively easy; and the nano cobalt phthalocyanine is generated. The prepared nano cobalt phthalocyanine has the advantages of being high in purity, short in cycle, low in energy consumption and economical; large-scale production is facilitated; and the nano cobalt phthalocyanine catalyst material prepared by the method has relatively long discharge time and relatively high discharge energy, and can be widely used as an Li / SOCl2 battery catalyst.

Description

technical field [0001] The invention belongs to Li / SOCl 2 The technical field of preparation of battery electrode catalytic materials, in particular to a Li / SOCl 2 Battery nano cobalt phthalocyanine catalyst material and preparation method thereof. Background technique [0002] Transition metal phthalocyanines have good thermal and chemical stability and become Li / SOCl 2 The main research object of battery catalyst, with Li / SOCl 2 In-depth research on batteries shows that transition metal phthalocyanine catalysts are effective for SOCl 2 Reduction to surface coordination catalytic reaction [Xu Z, Zhao J, Li H. Influence of the electronic configuration of the central metal ions on catalytic activity of metal phthalocyanines to Li / SOCl 2 battery[J].Journal of Power Sources,2009,194(2):1081-1084], added to SOCl 2 is not dissolved in but dispersed in SOCl 2 middle. The nanonization of phthalocyanine is beneficial to increase the active surface due to the small size effect...
