Description

Thomas Edison patented his accumulator in 1908. This was the first steel secondary element patented. In a secondary element or accumulator, the back reaction of the electricity generating reaction is possible. Thus, the cell can be charged and discharged. The Edison accumulator was used frequently up to the 1970ies. Today, modern accumulators include the Li-ion- or the Ni metalhydride battery.

In this experiment, the Edison accumulator is set-up, charged and discharged.
