Leclanche, Georges-Lionel

Ledanche cell (battery) one of the earliest practical non-rechargeable batteries (Georges-Lionel Leclanche, 1866). It uses a zinc anode (negative electrode) and a manganese dioxide cathode (positive electrode) with ammonium chloride solution as electrolyte. The initially liquid electrolyte... 

Georges-Lionel Leclanche developed the first prototype of the modem dry cell, Leclanche s cell, in 1866. The cell was designed with the purpose of providing a reliable and easily maintainable power source for telegraphic offices [1]. The original cell was assembled in a porous pot that worked as the separator [8]. The positive electrode consisted of manganese dioxide with a little mix of carbon, the negative...

Manganese dioxide, Mn02, (MDO) is a widely used as material in primary electrochemical cells. It is the positive electrode of the zinc-MnOa cell, invented in 1866 by the French engineer Georges-Lionel Leclanche [11]. Li-MnOa battery was developed by Sanyo in 1975 [12] as low-power supplies for watches, calculators and memory backups. The poor cyclability of MDOs observed at that time [13] has been improved by preparing composite dimensional manganese oxides (CDMOs) for the development of flat-type secondary batteries. Table 6.2 lists the chemical formula of selected Li-Mn-O compounds used in Li batteries.
