BY MARSHALL BRAIN, CHARLES W. BRYANT & CLINT PUMPHREY

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.


Although there are many different types of batteries, such as lithium polymer batteries, LiFePO4 batteries, Power Storage Batteryoriginal lithium batteries、lithium-ion batteries,;but the basic concept of their operation is still the same. When the device is connected to the battery, a reaction occurs that generates electrical energy. This is called an electrochemical reaction. The Italian physicist Earl Alessandro Walter first discovered the process in 1799, when he soaked it in metal sheets and brine with cardboard or paper to make a simple battery. Since then, scientists have made significant improvements to Walter's original design to make batteries of various materials in a variety 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.
