Edison–Lalande cell
The Edison–Lalande cell was a type of alkaline primary battery developed by Thomas Edison from an earlier design by Felix Lalande and Georges Chaperon. It consisted of plates of copper oxide and zinc in a solution of potassium hydroxide. The cell voltage was low (about 0.75 volts) but the internal resistance was also low so these cells were capable of delivering large currents. The cell could be replenished with fresh zinc and copper oxide plates and KOH solution for reuse.
