利用TAB快速测定正极活性物质Ni(OH)_2的性能

Rapid determination of performance of active material Ni(OH)_2 utilizing TAB

利用聚四氟乙烯乙炔黑(TAB)作为正极活性物质Ni(OH)_2的导电体和粘合剂,直接和Ni(OH)_2混合做成电极,进行恒电流充放电试验.与实效电池试验相比,由于Ni(OH)_2用量少,电极制作简易,从而能够快速测定和评价活性物质Ni(OH)_2的电性能.

The electrode was made of Ni(OH)2 and TAB(teflon acetylene black)and the latter was used as conductor and binder. The charge and discharge of Ni(OH)2 electrode were carried out by constant current. Because of the low content of Ni(OH)2 in electrode and the simplicity of electrode preparation, this method was shown to be capable of evaluating the electrochemical active performance of Ni(OH)2 effectively and rapidly.
