History of Power Banks and Lithium batteries<\/strong><\/span><\/h2>\r\n

When was the first call of a mobile phone?<\/strong><\/span><\/h3>\r\n

Martin Cooper, manager of Motorola,<\/strong> made a call to, Joel Engel, of Bell Labs of AT&T<\/a><\/strong>\u00a0on April 3, 1973, from Sixth Avenue in New York<\/a>, with a prototype of Motorola DynaTac 8000X.<\/strong> That was a mobile phone that weighed approximately one kilo and was about 13 inches (33 cm) tall taking into account the antenna. It was the first call made from a mobile phone.<\/span><\/p>\r\n

This prototype mobile phone used about ten hours to charge. Its battery had a range of just 30 minutes<\/strong>. Something that today is absolutely unthinkable<\/span><\/p>\r\n

Although the call was made in 1973, it was only in 1984 that the cell phone was released at a cost of USD 3,995. 300,000 units were thus sold. Ameritech Mobile Communications LLC<\/strong> was the first company in the United States to provide mobile phone service. The development of mobile phones was the first stage in the power bank history<\/strong><\/span><\/p>\r\n

Alessandro Volta Battery<\/strong><\/span><\/h2>\r\n

Alessandro Volta<\/strong> discovered the pile or column, which he initially called “artificial electric organ”<\/strong>, studying the effects of galvanism on frog legs. Volta thought that what he called galvanism was an animal electric current. It was named in honor of Galvani, founder of Nervous Physiology,<\/strong> who established this current by joining two different metals by means of nerves or muscles of an animal. In reality, galvanic current is a direct current (d.c.).<\/span><\/p>\r\n

Volta<\/strong> built the first stack that we can reproduce. Volta stacked discs of equal size of copper and zinc, alone or with tin, alternated, with a moistened cloth interspersed between each one. This “stack of discs” begins and ends with discs of different types. By connecting the disks at the ends with a wire, an electrical flow flowed. By impregnating the cloth with certain salts, the current obtained was much higher.<\/span><\/p>\r\n

A very important chapter in the history of the power bank,<\/strong> is who invented the lithium battery. John Goodenough<\/strong> invented, in 1980, the basic technology of lithium-ion batteries used in smartphones, notebooks, tablets, cameras and of course power banks. At age 97 he continues to investigate and is a professor of mechanical engineering at the University of Texas<\/strong> in Austin, USA<\/a> (you can send an email to (goodenough@mail.utexas.edu<\/a>).

John B. Goodenough won the Nobel Prize in Chemistry in 2019 alongside M. Stanley Whittingham and Akira Yoshino for the development of lithium-ion batteries<\/span><\/p>\r\n

In 1979, Goodenough showed that by using lithium cobalt oxide as the cathode of a lithium-ion rechargeable battery,<\/strong> it would be possible to achieve a high density of stored energy with an anode other than metallic lithium. This discovery paved the way for the development of lithium-ion batteries, which are now in portable electronic devices and electric vehicles.<\/span><\/p>\r\n

The lithium-ion battery developed by Goodenough in 1980 began to be marketed in the 1990s. Today it is the dominant battery technology for almost every portable device, including cars.<\/span><\/p>\r\n
