the anode of a dry cell is made up of?
zinc
the battery terminal (electrode) that develops a positive voltage polarity (the carbon electrode in a dry cell) is called the cathode and the electrode with a negative polarity (zinc in a dry cell) is called the anode. this is the "reverse" of the terminology used in an electrolytic cell or thermionic vacuum tube. the reason is that the terms anode and cathode are defined by the direction of electric current, not by their voltage. the anode is the terminal through which conventional current (positive charge) enters the cell from the external circuit, while the cathode is the terminal through which conventional current leaves the cell and flows into the external circuit. since a battery is a power source which provides the voltage which forces the current through the external circuit, the voltage on the cathode must be higher than the voltage on the anode, creating an electric field directed from cathode to anode, to force the positive charge out of the cathode through the resistance of the external circuit.

a "dry cell" uses a paste electrolyte, with only enough moisture to allow current to flow. unlike a wet cell, a dry cell can operate in any orientation without spilling, as it contains no free liquid, making it suitable for portable equipment. by comparison, the first wet cells were typically fragile glass containers with lead rods hanging from the open top and needed careful handling to avoid spillage. lead–acid batteries did not achieve the safety and portability of the dry cell until the development of the gel battery.
