The South Bank Lion, also known as the Red Lion, is a Coade stone sculpture of a standing male lion cast in 1837. It has stood at the east end of Westminster Bridge in London, to the north side of the bridge beside County Hall, since 1966.

With a standard electrode potential (SEP) of −0.76 volts, zinc is used as an anode material for batteries. (More reactive lithium (SEP −3.04 V) is used for anodes in lithium batteries ). Powdered zinc is used in
