World demand for energy is growing, more diverse, as time goes by. Developed as a convenient way to power electronic devices one of the sources of energy, and is an alkaline battery. Battery essentially in chemical reactions to produce electricity small container. Alkaline batteries are the most common and versatile type of battery, which gets its name because the alkaline electrolyte of potassium chloride, which is one of the chemicals it contains.

In the end what is the alkaline batteries it? Each alkaline battery terminals, or terminals - positive and negative terminals. Chemical reaction inside the battery E, the negative terminal of the battery aggregates. However, unless the negative terminal is connected to the positive terminal, the chemical reaction was stopped and did not produce more power. This is the reason, alkaline batteries can take a very long time in a drawer or shelf, there are still plenty of power when needed. If not used, the battery is not worn in a very short time period.

Typically, the battery is used to connect a number of devices, such as a motor, in the flashlight bulb, or a radio, such as battery negative electron flow through the wire of the device. And their power supplies, and then back into the positive. This completes a circuit to allow the chemical reaction to continue, and the cells produce more electrons. When the device is turned off, the circuit is interrupted, so that electrons can not flow in a complete circle battery, and will stop production of electronics, because they no longer connect terminals.

Alkaline battery using more modern types, has been in the 1960s introduced the first. The first one in 1800 by scientists volt battery Walt his cell stack alternating layers of zinc, salt water soaked tissues, and silver. The higher the stack, the higher the voltage generated by this arrangement. This type of battery is known as the photovoltaic pile. Modern alkaline batteries for photovoltaic pile, that is, two different types of metals, negative and positive terminals electricity, liquid separation, still using the same basic principles. One of the latest developments in the battery, has been the development of rechargeable alkaline batteries. Different formulas and combinations of materials, so that these can not only charge, unlike traditional alkaline batteries, but to maintain for many years with other types of rechargeable batteries are different, they are responsible for. These cells represent a form of stored energy, the final consumer, and an already reduced environmental impact and lower cost.
