空气电极催化层中导电炭材料的研究(I)

Study on conductive carbon in the catalyst layer of the air electrode(I)

选用一种新型炭黑材料Printex XE2-B作为锌空气电池空气电极的导电剂,同传统的乙炔黑作为空气电极的导电剂进行了比较。测试比表面积、电阻率、孔径分布情况、空气电极的极化曲线、放电性能。结果表明,采用Printex XE2-B炭黑材料作为锌空气电池空气电极的导电剂,电池电性能得到提高。

A new kind of carbon black-Printex XE2-B, is used as electrical conductive additive for air electrode of zinc-air battery, and is compared with acetylene black. Specific surface area, resistivity, and distribution of pore diameter of air electrode were measured. Polarization curve and operating performance of air electrode have been tested. The experimental results show that when Printex XE2-B is used as conductive additive for air electrode of zinc-air battery, the electrical performance of battery is improved.
