How does the battery generate its electricity?Unexpectedly, the invention of the battery was actually related to the frog

Speaking of batteries, it can be said to be a very common existence in modern life, whether in life or work, we will see all kinds of batteries, so do you know who invented the battery?How does the electricity in the battery work out?Why are batteries closely related to frogs?

How does the battery generate its electricity?

The mobile phones, flashlights and other electrical devices we use store a certain amount of electricity in the internal battery, so do you know how the battery generates electricity?

Electric energy is the ability to direct electricity consumption to do work in various forms. Electric energy is a kind of economic, practical, clean and easy to control and convert energy. The utilization of electric energy is an important symbol of the second industrial Revolution.

In fact, batteries use chemical reactions to release energy, and then generate electricity.In nature, there is always a trend of energy conversion from high energy state to low energy state, so the chemical reactions under normal conditions are the release of energy.

Only the chemical reaction when the energy is applied is to absorb the energy, but while absorbing the energy, it also increases the chemical energy. When the applied energy disappears, the chemical energy of the high-energy state will release the absorbed energy again, which is the manufacturing principle of batteries.

Why is the invention of batteries related to frogs?

So why is the invention of the battery always a frog?How do they connect between them?

On this point, we should also start with an anatomical frog experiment conducted by Italian scientist Luigi Gavani in 1780. He accidentally touched the frog's thigh with two different metal pieces at the same time, and the muscles of the frog's leg immediately twitched, as if it were hit by an electric current.

Gavani boldly speculated that the frog could produce electricity and called it "bioelectricity," but a university professor disagreed. He thought that the source of the current should be the contact between the two metals, not the body, and then conducted his own experiments.

This was the first battery in human history, made of zinc, silver, and cardboard, and the professor, the famous Alessandro volt, named the battery the "Volt Reap."

The development of batteries

Although the electric current generated by this volt reactor is very small, it is precisely because of this weak electric current that opens the door to the wisdom of countless scientists.

In 1850, French physicists invented lead-acid batteries, which were widely used in the automotive industry; and 49 years later, in 1899, Swedish physicists invented a nickel-chromium battery, such as remote-controlled toy cars for children.

In 1902, the famous Thomas Edison invented the alkaline battery, it is now the most common disposable dry battery, until 1991, the lithium battery was officially launched, it is smaller, more power storage capacity, widely used by people.
