The imminent need for energy sources in human history leads us to analyze the history and potential of a well-known market, the battery industry. When we think about batteries we don't just come to the thought of an energy source, but we must also recognize the added value they have as portable. The portability of these batteries has great advantages, think of a mine, think of a rescue, a trip and many other situations that can come to mind. In my head it would not be possible to imagine a modern society without these ingenious devices that we commonly call batteries. Say no to plagiarism.

Get an original essayA man named Alessandro Volta had some knowledge of electrostatic and electrical force but after the creation of the voltaic cell he was able to demonstrate the presence of electromotive force (emf/voltage), which can be measured in volts. In 1799 Volta invented the battery by stacking many voltaic cells in series, one on top of the other. It was able to produce a voltage of approximately 50 volts for a 32-cell battery. Volta thought, however, that his cells were an inexhaustible source of electrical force, and ignored the fact that this electrical energy came from a chemical reaction that eventually ran out. By the year 1836 batteries provided more reliable power and were adopted in industry and some households, it should also be noted that electrical distribution networks did not exist then. Towards the end of the 19th century, the creation of dry batteries made them even more practical and reliable. Batteries haven't evolved much since the 1800s; Evidence of this would be the commonly used automotive battery. The basic principle has prevailed, the heaviness and toxicity of the large vehicle battery remain the same. Even with these limitations, business has been good for those in the battery industry. The global market for large and advanced batteries alone grew from $8.4 billion in 2006 to $8.9 billion in 2007. And this market is expected to reach $22.4 billion by 2022. Lithium-ion batteries have replaced older battery types over the years. in recent years and, as people become greener, they tend to move away from oil, which in turn leads to further development of these batteries. Improvements made in the field of lithium-ion batteries will lead to more stable batteries, with greater capacity and with a longer life. Lithium-ion batteries appeared in 1990. Due to the growing popularity of lithium-ion batteries, they are used in everything from small cell phones to large hybrid or fully electric vehicles. The lithium-ion batteries produced offer two to three times higher energy densities and five to six times higher power densities than other conventional batteries. Therefore, like most batteries, you want to have the highest capacity achievable with the smallest cell you can build, and that's why the move to lithium-ion batteries began. These batteries already have a high energy density, a high galvanic potential, a low self-discharge rate, have a low weight and have a poor memory effect. The memory effect is a tendency for cells to lose capacity due to improper charging or discharging, which reduces cell life and operating times. As for electric vehicles, lithium-ion cells must have the ability to discharge, to create enough energy to accelerate on the highway. This ability to unload.
