A battery is an electrochemical cell that can be charged to provide a static power or released electrical charge when it needed. Generally, a battery composition of an anode, a cathode, and an electrolyte.
There are various types of batteries out there. Common types of fo commercial batteries and some of their characteristics and Typical Uses.
Sealed Lead Acid Battery.
Characteristics: Sealed Lead Acid Battery can hold a charge for up to 3 years.
Typical Uses: Backup emergency power Source.
Nickel-Cadmium Battery.
Characteristics: Fast, even every discharge.
Typical Uses: appliances, audio and video equipment, toy; most popular battery.
Nickel-Metal Hydride battery.
Characteristics: Typical power capacity i1.2 V - 1200 to 1500 mAh; extended life 2300 mAh; 2.5 to 4 hours battery life.
Typical Uses:Portable computers; cellular phones; same as for Ni-Cd batteries.
Lithium-Ion battery.
Characteristics: Stable and safe; highest energy capacity.
Typical Uses: Portable computers; cellular phones; same as for Ni-Cd batteries.
How Battery Works?
Can you imagine a world where all electrical appliances need to be plugged in? Flashlights, cellphones, and toys would be tethered to
electrical outlets, making them clumsy and inconvenient. Batteries deliver portable available sources of energy for powering devices without wires or cables. A Leclanche cell may be a common sort of battery used today. It basically converts stored energy into electricity.
In the most elementary terms, A battery cell is formed from three components: an anode (-), a cathode(+) and therefore the electrolyte. In the dry cell, zinc is the anode (-), the graphite core is the cathode(+), and ammonium chloride paste acts as an electrolyte.
Due to a reaction within the battery, the anode builds up more than electrons. this causes an electrical difference between the anode and therefore the cathode. the electrons want to rearrange themselves and displace the additional electrons within the cathode. However, the electrolyte ensures that the electrons cannot travel on to the cathode.
When the circuit is closed (with the assistance of a "conductive path" between the anode and cathode) the electrons are ready to visit the cathode.
It, in turn, powers any equipment along the way.
Over time this electrochemical process alters the chemical makeup within the anode and cathode and eventually, they stop providing electrons. And this is how a battery "dies".
Batteries provide us with a mobile source of power, that creates many model conveniences possible.
