Batteries are basic sources of energy for almost all of us. We don’t even notice how often we use them in everyday life.
The development of batteries is closely related to the discovery of electricity. And after that was practically since 550 BC. Chr (Thales of Miletus) permanently sought. By rubbing amber with an animal skin, he discovered that he could attract small particles of straw and feathers to cloth. Hence the name electricity comes from the ancient Greek word for amber: electro. In 1780, while doing research in Bologna, the Italian doctor Luigi Galvani discovered that a frog’s leg twitches when it comes into contact with iron and copper. He himself believed this to be an electrical effect and called his discovery animal electricity. His experiments were later continued by Alessandro Volta from Como and Volta actually managed to create the first precursor of the battery. Cardboard discs soaked in salt solution separated thin copper and zinc discs from one another: the voltaic pile was complete. It was the year 1800. Around 50 years later, mass production of lead-acid batteries began. It was then Thomas Alva Edison who presented the first so-called alkaline batteries around the turn of the century (1901). In other words: nickel-iron batteries with alkaline electrolytes, which are formed by the reaction of carbon dioxide from the ambient air with caustic soda. This is how sodium carbonate is formed in the electrolytes. The Swede Waldemar Jungner also used alkaline electrolytes instead of acid. The American John B. Goodenough first used lithium as a positive pole for batteries in 1986 and received the Nobel Prize in Chemistry for this in 2019.
