Volt was invented in 1800 on March 20th, and the invention of battery was announced in Ford, which caused a great sensation in the world. 1799, Italian physicist Volt soaked a zinc plate and a tin plate in salt water, and then he found a wire connecting two metals, and there was a current flowing between the two metals. After that, he put many zinc plates and silver plates on it.
After that, many inventors continued to develop batteries. At 1800, Alessandro? Volt invented the electric reactor and developed a practical power generation method. Volt pile is the first "wet battery" in the world. This kind of battery can provide reliable and stable current. Because of the stack, there is no guarantee to provide current for a long time. Later, an Englishman invented Daniel battery, which has two kinds of electrolytes, copper sulfate and zinc sulfate. Compared with the electric pile, this kind of battery can provide longer power. Daniel battery is widely used in telegrams, telephones, doorbells, etc. It has brought great convenience to mankind.
Later, William Robert Grove invented the first fuel cell. After that, scientists continued to refine and improve batteries, and developed liquid batteries, rechargeable batteries, zinc-manganese batteries, acid batteries and so on. Later, many new batteries were developed. Compared with the previous batteries, these newly developed batteries have improved many shortcomings and improved a lot. The invention of batteries has brought us great convenience. It is widely used in people's lives.
