Electricty - Battery, Tyer's Battery (Cell / Pile)
Battery, Tyer's Battery (showing interior sections). A modification (as regards the positive element) of Smee's battery. In Tyer's cell, the bottom of the battery jar contains a quantity of mercury in which pieces of zinc are thrown, and this constitutes the positive element. A ball of zinc at the end of an insulated copper wire affords the connection with the zinc and mercury. Its great advantage is that the smallest scraps of zinc can be used in it, by being dropped into the mercury. The negative plate is platinized silver; the exciting liquid, dilute sulphuric acid
