Battery Essay

Helps me memorize Battery Essay from 7th Grade

Intro 1

Hello, my name is Aariv Dhanuka, and I will be explaining to you why the battery is the most important invention from the 1800s.

Intro 2

Batteries are something we use everyday, from small things like RC cars and alarm clocks to things like your laptop or, even, your car.

Intro 3

The battery is a very useful innovation, having spurred the creation of many other devices.

Intro 4

It has altered this world past, present, and future.

Intro 5 (Thesis)

A very important invention, the battery helped us get to where we are and has powered many life-changing machines.

First 1

A battery works by producing electricity from a chemical reaction.

First 2

There are two types of batteries: wet-cell and dry-cell.

First 3

A wet-cell battery uses some kind of liquid to conduct electricity, while dry-cell batteries use solids or gases.

First 4

Either way, both batteries are made of the same components; a negative electrode, an electrolyte that conducts ions, a seperator which is also an ion conductor, and a positive electrode.

First 5

Generally, in a wet-cell, the electrolyte is liquid, while it is solid in a dry-cell.

First 6

Research into storing electricity was first started by Luigi Galvani in 1780, who accidentally connected a brass hook to a frog lying on a metal hanger.

First 7

The frog's leg twitched when he touched an electric spark to the hook, so Galvani thought the leg itself was holding a current.

First 8

Galvani called this "intrinsic electricity", and claimed that every organism had some.

First 9

However, Volta later proved that it wasn't the leg, but the brass hook being connected to a metal hanger that created a circuit, which caused the frog's leg to twitch when a current ran through it.

First 10

This idea, when coupled with Volta's discovery that certain fluids would generate a continuous flow of electric power when used as a conductor, led to the invention of the first battery.

Second 1

The person most credited with the invention of the battery is Alessandro Volta.

Second 2

His battery, called the Voltaic Pile, conducted electricity through alternating discs of zinc and copper with pieces of cardboard soaked in brine between them.

Second 3

It was the first real battery ever invented; however, it couldn't produce an electrical current for a long period of time.

Second 4

Thus, in 1836, John F. Daniell invented the Daniell Cell.

Second 5

It used two electrolytes of copper sulfate and zinc sulfate, and produced 1.1 volts of electricity very reliably.

Second 6

It was used for over 100 years to power telegraphs, telephones, and dorbells.

Second 7

In 1859, though, Gaston Plante invented a reachargeable lead-acid battery.

Second 8

This battery is still used today, primarily in in cars.

Second 9

However, all these batteries are wet-cell, which we generally don't use today; the first dry-cell battery was invented by Georges Leclanche.

Second 10

It consisted of crushed manganese dioxide with carbon mixed in and ammonium chloride paste, with a zinc rod.

Second 11

Thus, it was called a carbon-zinc cell.

Second 12

This is the main battery we use today, although improvements on it were made in 1949.

Third 1

The battery has many day-to-day uses from video game consoles like the Nintendo Wii to life-saving devices such as AEDs

Third 2

Its first true use, in 1800, was for a miner's safety lamp.

Third 3

Sir Humphry Davy, the inventor of it, implemented the battery into the lamp, and witnesses said that it produced "the most brilliant ascending arch of light ever seen."

Third 4

After the Daniell cell was invented, it was incorporated into telegraph lines for AC (alternating current), and to everyone's amazement, the battery AND AC, two things that we now take for granted, lit up the Chicago World Fair in 1893.

Third 5

Electricity was thus made widely available to humanity to improve the quality of life.

Conclusion 1

Overall, the battery was a very important invention of the 1800s.

Conclusion 2

It has helped us make many technologies, not just for our entertainment but for life-saving devices.

Conclusion 3

There are many future uses for the battery, too; for example, EVs make our planet cleaner and could reduce global climate change by a significant level.

Conclusion 4

Thus, the battery is extremely important to us.
