| Abstract: | The effects of small addition of CdO, Ca(OH)2 and Zn dust to the plastic bonded zinc electrode have been evaluated through triangular potential sweep voltammetry, potentiodynamic polarization (with temperature effect), impedance measurements, solution analysis and Porosity measurements. In the case of CdO additive, a composition of 2% is preferred because of its enhanced ageing behaviour, good high temperature performance and minimum shape change despite its increased standby corrosion. 1% Ca(OH)2 gives both good ageing behaviour as well as minimum idle corrosion. The additive Zn dust is not recommended owing to its poor ageing behaviour. Based on the above results, the suitable zinc electrode composition is suggested. |
