A battery, by definition, consists of a group of two or more primary or secondary battery cells, which convert chemical energy into electrical energy. A portion of the chemical energy a cell produces is transformed into heat, and a portion into an electric current.

Primary battery cells can only be renewed during down time, when they replenish their chemicals. When one reach for his or her emergency flashlight, which contains a type of primary cell named an ordinary cell, and it fails to light up, one falls victim of this very principle.

Each and every primary cell uses various chemicals, and contains electrodes and an electrolyte, a liquid. Electrodes, a.k.a. "cell elements," consist of either two different metals, or one metal and carbon. Element number one, the cathode, is primarily zinc. Element number two, the anode, is primarily carbon.

A chemical action sets the electrons free, when it triggers the cathode slowly to dissolve into the liquid electrolyte. A circuit provides the escape route for the newly paroled electrons, and they rush down the hatch in the form of an electric current. Unfortunately, their freedom is short-lived, because, once an electrical conductor is connected to the two elements, the current flowing through it is recaptured as electricity.

Secondary battery cells merit less discussion, as they automatically recharge, when an electric current is injected through them. Primary examples of a secondary battery cells are the storage cells used to start, or not to start, our car batteries. Because a storage battery does not actually store electricity, it instills in one a false sense of security. One is well advised to carry jumper cables in our cars, for those times when, much to ones chagrin, the battery fails to start.

The misnomered "storage battery," draws its power from chemical charges. Inside a storage battery, one finds a set of plates made of metallic lead, and a set made of lead peroxide. When both sets of plates are immersed in sulphuric acid, they undergo a chemical change, which transforms them into lead sulphate, which in turn produces the electrical current in the storage battery, which does not store. A word of caution...do not try this one at home (CoolQuiz).

Yes. A battery converts chemical energy into electrical energy, so technically, yes, a battery creates electricity, though there's a price. A battery utilizes the chemical interaction between an electrolyte and the electrodes to create electricity. Once the chemical reaction has completed, battery quits producing electricity. Some batteries may use electrical energy to cause a chemical change in a depleted battery to 'recharge' it. Other batteries are one way, and when exhausted, they're thrown away and replaced.

Edit: In response to subsequent replies, I have to disagree. Electricity can be produced by a chemical reaction WITHOUT electrical energy having been put 'into' the battery first place. Yes, a battery may be a 'storage' device, but electricity may be created without the 'electricity' having been stored in the battery in the first place. For example. A battery can be made from a lemon, a zinc-plated roofing nail and some copper.

No body 'stored' or 'put' any electricity' into the lemon!

It's a matter of semantics.
Electricity can be created with a chemical reaction (a battery) or a physical process (a generator). So yes, technically electricity is "created".

ENERGY, however, cannot be created. The electricity "created" in the battery was previously stored in the form of the potential energy in the chemical bonds. Where did that energy come from? It came from the industrial processes that created the chemicals. What about the lemon, where did that energy come from? From the chemical components of the lemon juice. These chemicals (or the raw materials of them) were in turn extracted from the soil in a process that was driven by the sun (photosynthesis). In fact, if you follow the chain of energy far enough, a lot of our energy comes from the sun even if no solar panels are involved.

So yes, batteries create electricity... but they do so from energy that was previously stored in the form of chemicals.

No.

A battery is a storage medium for electricity, not a generator of it.

The generator which creates the energy is either a chemical, or mechanical means. Chemical means are not very powerful producers, think potato clock, and electromechanical means such as generators, or alternators are the preferred method.

The question was does a battery create electricity. The answer is 'yes'. As far as power is concerned. An automotive battery will produce substantial power just by the addition of acid to the plates without any 'charging'. This is purely a 'chemical' production of electricity.

Yes, a battery creates electricity through a chemical reaction that involves a reduction of acid. Some use a metal like nickle or cadmium and some use straight acid...simple voltaic cells can even be made out of potatoes!

In any event, the answer to the original question is yes, a battery may 'create' an electrical potential without any external electrical source .

Yes but it needs a complete circuit to get started.
