Cardon Battery
Kind : zinc-manganese Cardon battery
Spec : R20 , R6 , R03
The most common type of battery used today is the Cardon battery. There are many different types of batteries ranging from the relatively large "flashlight" batteries to the minaturized versions used for wristwatches or calculators. Although they vary widely in composition and form, they all work on the sample principle. A dry battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder as shown below.
In the most common type of Cardon battery, the cathode is composed of a form of elemental carbon called graphite, which serves as a solid support for the reduction half-reaction. In an acidic dry cell, the reduction reaction occurs within the moist paste comprised of ammonium chloride (NH4Cl) and manganese dioxide (MnO2):
2NH4+ + 2MnO2 + 2e- ------> Mn2O3 + 2NH3 + H2O
A thin zinc cylinder serves as the anode and it undergoes oxidation:
Zn (s) ---------------> Zn+2 + 2e-
This dry cell "couple" produces about 1.5 volts. ( These "dry cells" can also be linked in series to boost the voltage produced).
We can offer model : R20,R6 and R03
