Lead dioxide anode is preferred over lead strip because it has a higher oxygen overpotential, which allows for a higher efficiency in the oxygen evolution reaction. This means that less energy is required to produce oxygen at the anode, making it more cost-effective and environmentally friendly.
Lead dioxide anode is more durable than lead strip because it has a higher resistance to corrosion. This is due to the formation of a passivating layer on the surface of the anode, which protects it from further corrosion. In comparison, lead strip is more prone to corrosion in the harsh conditions of an electrochemical cell.
No, lead dioxide anode is not suitable for all types of electrochemical cells. It is primarily used in cells that require the production of oxygen at the anode, such as in the production of chlorine gas or in the purification of water. In other types of cells, different electrode materials may be more suitable.
While lead dioxide anode is generally considered safe for use in electrochemical cells, there are some potential health and environmental concerns. Lead is a toxic metal, and if not handled properly, it can pose a risk to human health and the environment. However, proper handling and disposal procedures can minimize these risks.
Yes, lead dioxide anode is typically more expensive than lead strip. This is due to the additional processing and materials required to produce the anode. However, the higher efficiency and durability of lead dioxide anode can offset this cost in the long run, making it a more cost-effective option for certain applications.
