Abstract

The invention discloses a whisker type conducting material used for batteries. The conducting material consists of the following raw materials in parts by weight: 3 to 4 parts of potassium hexatitanate whisker, 5 to 7 parts of polyamide wax micro powder, 0.1 to 0.3 part of dodecyl dimethyl betaine, 100 to 120 parts of pyrrole, 3 to 5 parts of dibenzoyl peroxide, 1 to 2 parts of lauryl mercaptan and 2 to 4 parts of triethylamine. According to the conducting material, the triethylamine is used for treating the potassium hexatitanate whisker, so that the surface activity of the whisker is effectively improved; by using the pyrrole as a monomer, obtained polypyrrole is blended with the whisker after surface modification through polymerization under the effect of an initiator, and the mechanical and conductive stability of the finished product conducting material is realized.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a conductive material for whisker-shaped batteries and a preparation method thereof. Background technique [0002] Polypyrrole is usually an amorphous black solid, and pyrrole is used as a monomer to make a conductive film through electrochemical oxidation polymerization. The oxidant is usually ferric chloride, ammonium persulfate, etc. Or synthesized by chemical polymerization, electrochemical anodic oxidation of pyrrole is also an effective means to prepare polypyrrole. It is a conductive polymer with good air stability and easy electrochemical polymerization to form a film, insoluble and infusible. It can electrochemically oxidize and polymerize into a film in acidic aqueous solution and various organic electrolytes, and its properties such as electrical conductivity and mechanical strength are closely related to the polymerization conditions such as electrolyte anion, so...
