What are battery made of?

Answer 1

There are several types of battery - mainly Alkali/Alkaline. The main componants would be metal, for the contact points at either end, and Plastic of some sort for the covering or label.
manganese dioxide, carbon black (graphite), and an electrolyte (potassium hydroxide in solution)
A car battery is made of a plastic case, in which there are 6 compartments, inside each there are several plates made of a frame covered with a lead based paste. These sit in an acid bath, which works with the plates to make a chemical reaction which makes the battery volts.

Devices, consisting of a group of electrochemical cells that convert chemical energy into electrical energy; the term is also commonly applied to a single cell of this kind. A wet cell contains free liquid electrolyte; in a dry cell the electrolyte is held in an absorbent material. Chemicals are arranged so that electrons released from the battery's negative electrode flow through a circuit outside the battery (in the device powered by it) to the battery's positive electrode. The battery's voltage depends on the chemicals used and the number of cells (in series); the current depends on the resistance in the total circuit (including the battery - and thus on electrode size). Multiple batteries may be connected in series (the positive electrode of one to the negative electrode of the next), which increases total voltage, or in parallel (positive to positive and negative to negative), which increases total current. Batteries that are not rechargeable include standard dry cells used in flashlights and certain wet cells for marine, mine, highway, and military use. Car batteries, many kinds of dry cells used in cordless appliances, and batteries for certain military and aerospace uses may be recharged repeatedly.

A battery is made out of Metal, Acid and Gas.

vered with a lead based paste. These sit in an acid bath, which works with the plates to make a chemical reaction which makes the battery volts.

We should not forget lithium in some batteries and also nickel and cadmium in others.

Answer 2

Batteries are made of what I believe is copper, zinc or metal and the outside of the battery protects the energy but slowly leaks it depends on what brand and what battery. Duracell make battery to protect the energy for up to 10 years.
