Different Types of Batteries and their Applications

Introduction

Batteries are a set of 1 or more cells whose chemical reactions create a flow of electrons during a circuit. All batteries are made from three basic components: an anode (the ‘-‘ side), a cathode (the ‘+’ side), and a few quite electrolyte (a substance that chemically reacts with the anode and cathode).

When the anode and cathode of A battery are connected to a circuit, a reaction takes place between the anode and therefore the electrolyte.

This reaction causes electrons to flow through the circuit and back to the cathode where another reaction takes place. When the fabric within the cathode or anode is consumed or not ready to be utilized in the reaction, the battery is unable to supply electricity. At that time, your battery is “dead.”

Different Types of Batteries and its' Applications

Batteries that have got to be thrown away after use are referred to as primary batteries. Batteries that will be recharged are called secondary batteries.

Without batteries, your quadcopter would need to be tethered to the wall, you’d need to hand-crank your car, and your Xbox controller would need to plug altogether the time (like within the good old days). Batteries offer how to store electrical P.E. during a portable container.

The invention of the fashionable battery is usually attributed to Alessandro Volta.

The Leclanche cell

Up until the late 1800s, the electrolyte in batteries was during a liquid state. This made battery transportation a really careful endeavor, and most batteries were never intended to be moved once attached to the circuit.

In 1866, Georges Leclanché created A battery employing a zinc anode, a manganese dioxide cathode, and a sal ammoniac solution for the electrolyte. While the electrolyte within the Leclanche cell was still a liquid, the battery’s chemistry proved to be a crucial step for the invention of the Leclanche cell.

Carl Gassner found out the way to create an electrolyte paste out of sal ammoniac and Plaster of Paris. He patented the new “dry cell” battery in 1886 in Germany.

While carbon isn’t utilized in the reaction, it performs a crucial role as an electrical conductor within the zinc-carbon battery.

20th Century Rechargeable Batteries

In the 1970s, COMSAT developed the nickel-hydrogen battery to be used in communication satellites. These batteries store hydrogen during a pressurized, gaseous form. Many man-made satellites, just like the International space platform, still believe nickel-hydrogen batteries.

The research of several companies since the late 1960s resulted in the creation of the nickel-metal hydride (NiMH) battery. NiMH batteries were released to the buyer market in 1989 and provided a smaller, cheaper alternative to the rechargeable nickel-hydrogen cells.

Asahi Chemical of Japan built the primary lithium-ion battery in 1985, and Sony created the primary commercial lithium-ion battery in 1991. within the late 1990s, a soft, flexible casing was created for lithium-ion batteries and gave rise to the “lithium polymer” or “LiPo” battery.

Components

Batteries are made from three basic components: an anode, a cathode, and an electrolyte. A separator is usually wont to prevent the anode and cathode from touching if the electrolyte isn’t sufficient. To store these components, batteries usually have some quite casing.

Both the anode and cathode are sorts of electrodes. Electrodes are conductors through which electricity enters or leaves a component during a circuit.

Different Types of Batteries and its' Applications

Anode

Electrons effuse from the anode during a device connected to a circuit. this suggests that conventional “current” flows into an anode.

In a battery, the reaction between the anode and electrolyte causes a build from electrons within the anode. These electrons want to maneuver to the cathode but cannot undergo the electrolyte or separator.

Cathode

Electrons flow into the cathode during a device connected to a circuit. this suggests that conventional “current” flows out from a cathode.

In batteries, the reaction in or around the cathode uses the electrons produced within the anode. the sole way for the electrons to urge the cathode is thru a circuit, external to the battery.

Dead Battery

The chemicals within the battery will ultimately reach a state of equilibrium. during this state, the chemicals will not have a bent to react, and as a result, the battery won’t generate any longer current. At now, the battery is taken into account “dead.”

Primary cells must be disposed of when the battery is dead. Secondary cells are often recharged, and this is often accomplished by applying a reverse current through the battery. Recharging occurs when the chemicals perform another series of reactions to require them back to their original state.

Types of Batteries

Batteries are classified into 2 types:
Non-rechargeable batteries (primary batteries)
• Rechargeable batteries (secondary batteries)

Non-rechargeable Batteries

These are basically considered as primary batteries because they will be used just one occasion. These batteries can’t be recharged and used again. Let’s see about the regular, lifestyle primary batteries that we see.

• Alkaline batteries: it’s basically constructed with the chemical composition of Zinc (Zn) and manganese dioxide (MnO2) because the electrolyte utilized in it’s potash which is only an alkaline substance the battery is known as an alkaline battery having he power density of 100 Wh/Kg.

• Coin cell batteries: The chemical composition of coil cell batteries is additionally alkaline. aside from alkaline composition, lithium and silver oxide chemicals are going to be wont to manufacture these batteries which are more efficient in providing steady and stable voltage in such a little size. It’s a power density of 270 Wh/Kg.

Rechargeable Batteries

These are generally called as secondary batteries which may be recharged and may be reused. Though the value is high, they will be recharged and reused and may have an enormous lifetime when properly used and safely charged.

Lead-acid batteries

It consists of lead-acid which is extremely cheap and seen mostly in cars and vehicles to power the lighting systems in it. These are more preferable within the products where the size/space and weight don’t matter.

These come with the nominal voltage starting 2V to24V and most ordinarily seen as 2V, 6V, 12V, and 24V batteries. It’s the power density of seven Wh/Kg.

Different Types of Batteries and its' Applications

Ni-Cd batteries

These batteries are made from Nickel and Cadmium chemical composition. Though these are very rarely used, these are rock bottom and their discharge rate is extremely low in comparison to NiMH batteries.

These are available altogether standard sizes like AA, AAA, C, and rectangular shapes. The nominal voltage is 1.2V, often connected together during a set of three which provides 3.6V. It’s the power density of 60 Wh/Kg.

Ni-MH batteries

The Nickel – Metal Hydride batteries are much preferable than Ni-Cad batteries due to their lower environmental impact. Its nominal voltage is 1.25 V which is bigger than Ni-Cad batteries.

It’s less nominal voltage than alkaline batteries and that they are good replacement thanks to its availability and fewer environmental impact. the facility density of Ni-MH batteries is 100 Wh/Kg.

Applications:

Used in all applications almost like the alkaline and Ni-Cad batteries.
