Power
Think of a battery as a small power plant that converts a chemical reaction into electrical energy. Various dry cell (or alkaline) batteries can differ in several ways, but they all have the same basic components. For even more details, visit our What’s Inside a Battery page or our Battery Chemistry page.
It''s easier to understand how batteries work when you see how they''re put together.
Container —It all starts with an empty steel can – the battery container.
Cathode Mix —Finely-ground powders of manganese dioxide and conductors that carry a naturally-occurring electrical charge are molded to the inside wall of the empty container.
Separator —Separator paper is inserted to keep the cathode from touching the anode.
Anode —The anode, which carries a negative electrical charge, plus potassium hydroxide electrolyte are then pumped into each container.
Collector —The brass pin, which forms the negative current collector, is inserted into the battery, which is then sealed and capped.
Imagine a world where everything that used electricity had to be plugged in. Flashlights, hearing aids, cell phones and other portable devices would be tethered to electrical outlets, rendering them awkward and cumbersome. Cars couldn''t be started with the simple turn of a key; a strenuous cranking would be required to get the pistons moving. Wires would be strung everywhere, creating a safety hazard and an unsightly mess. Thankfully, batteries provide us with a mobile source of power that makes many modern conveniences possible.
While there are many different types of batteries, the basic concept by which they function remains the same. When a device is connected to a battery, a reaction occurs that produces electrical energy. This is known as an electrochemical reaction. Italian physicist Count Alessandro Volta first discovered this process in 1799 when he created a simple battery from metal plates and brine-soaked cardboard or paper. Since then, scientists have greatly improved upon Volta''s original design to create batteries made from a variety of materials that come in a multitude of sizes.
Today, batteries are all around us. They power our wristwatches for months at a time. They keep our alarm clocks and telephones working, even if the electricity goes out. They run our smoke detectors, electric razors, power drills, mp3 players, thermostats -- and the list goes on. If you''re reading this article on your laptop or smartphone, you may even be using batteries right now! However, because these portable power packs are so prevalent, it''s very easy to take them for granted. This article will give you a greater appreciation for batteries by exploring their history, as well as the basic parts, reactions and processes that make them work. So cut that cord and click through our informative guide to charge up your knowledge of batteries.
Batteries are stores of chemical energy that can be converted to electrical energy and used as a power source.

Meet the Batt-men! They're well they're batteries.
But, unlike that Bat-man they might be able to save the world in real life (plus they have a lot more outfits)
First off there's alkaline Batt-man. He comes in little cylinders and powers our torches and, yes, our TV remotes. He's really handy if you need a wee bit of power in a portable package. But he''s not very energetic.
Unlike gadget-carrying Lithium-ion Batt-man, who powers computers, mobile phones and even electric cars. He can be recharged and he packs a real punch.
Big lithium-ion batteries are used in places like solar farms to store extra electricity, which can then be used to power our homes when the sun goes down.
But lithium-ion batteries are expensive, there isn''t much lithium about and mining it causes pollution, and he can get hot which wastes energy.
But there may be more heroes to the rescue.
Like Hydrogen Batt-man. He isn't even really a battery – he's an engine. When we combine hydrogen with oxygen in a fuel cell, it generates electricity. And unlike smelly petrol engines, its only output is H20 - water!
Hydrogen fuel cells already power lots of our vehicles, like forklift trucks and buses. But hydrogen batt-man has a bit of a pollution problem. At the moment his hydrogen mainly comes from the burning of fossil fuels, which pollute our atmosphere.
