6 FAQs about [Mercury-free battery zinc powder production process]

How to make zinc battery electrode?

To prepare the zinc battery electrode, first a powder mixture was produced. Four grams of electrolytic Zn powder were mixed with few percents of HgO and PVA binder. Then, the mixture was pressed in a die under pressure of 5 MPa. Two electrodes were made in this way from each powder batch.

How to produce zinc powder?

Zinc powder can be produced using some processes such as atomization and electrolysis. It is obvious the electrolytic zinc powder with dendritic and porous morphology improves the battery operation. Several investigators have studied zinc–silver batteries , , .

How are electrolytic zinc powders produced?

Electrolytic zinc powders were produced by electrolysis of alkaline zincate solutions. Current density (C.D), zincate concentration and electrolyte concentration (KOH concentration) were chosen as three main variable parameters. Other parameters, as bath temperature and electrodes distances, were kept constant.

How to produce zinc powder through electrolysis of alkaline solutions?

A research conducted to produce zinc powder through electrolysis of alkaline solutions by using various concentrations of KOH and zincate in the bath. Different current densities were applied for each concentration and then, morphological changes of Zn powder batches were examined by scanning electron microscopy.

Does Mercury affect the load capacity of a zinc powder electrode?

The influence of mercury on the load capability of a zinc powder electrode (0.2 mm) is illustrated in Figure 7. It is obvious, that amalgamated zinc exhibits an initial peak current of 171 about 24 mA/mg Zn while the peak current of mercury-free zinc is more than 20 times smaller.

Is it necessary to produce mercury-free manganese dioxide-zinc primary batteries?

For that reason it may be necessary to produce mercury-free manganese dioxide-zinc primary batteries. Worldwide, more than 12 billions of such batteries are manufactured - and thrown away. It can be done, industry has produced mercury-free manganese dioxide batteries.
