How Are Produced Lithium Batteries?




Notebooks, tablets, smartphones ... If today you can count on plenty of kitchen appliances apparatus, much of this mobility is due to a metal that besides pushover, is also very difficult to be found there: lithium. Since its properties were discovered electrical conductivity, the metal has been used in various work fronts.

Besides the aforementioned portable electronics, today the lithium (Li-Ion) ion also inhabit some heavy machinery and various models of motor vehicles. With this expansion of use, the production of the material has also gained a souped. Nevertheless, the demand of the metal can still show greater than supply, after all, the production process of lithium is expensive and time consuming.

With lithium in hand, specialized companies make metal processing . This happens in stages. First, lithium is mixed with a kind of ink that gives him the appearance of a sheet of aluminum foil after going through all stages.

Then he is pressed and goes through several rollers high power, something like a kind of gigantic printer, kneading, cutting and adjusting the metal so that it is passed forward. This turns into a superfine metal blade, with less than 0.2 mm thick. This metal finally is wound on the coil form and goes to next step which is to manufacture batteries.

These large rolls are divided into tiny lithium coils vary in size according to the type and size of the battery. There round alternative, used in large automobile batteries, and other rectangular, present in laptops, for example. These coils get smaller, however, several "additives".

Because lithium be sticky and soft, it needs to be "married" with a roll of polypropylene film, which ensures that it will not end up sticking and mixing. If a blade join the other, the metal loses its qualities and unused battery dies.

These rolls, Now antigrude protection, return to the winding machines. This time, the number of turns required will according to the battery type. A 3.56 volts, for example, need 26 rotations until the battery cell is created. Once wrapped, she goes to a kind of oven, which causes everything to be compressed and vacuum is firm and solid.

With battery cells produced robots perform the production of contacts. Using liquid metal, everything is recorded on its surface, giving "access" to resources of lithium and allowing Sourcing communicate with her. So, everything finally turns into a battery, with the movement of ions so your mobile gadget is always running! Smile

And, so... Because it is a metal, lithium historically been extracted through similar means to their "cousins​​", ie, digging yourself a hole in the ground, some stones were removed and the miners cause an explosion. With this, they could separate the materials that interested and sent for processing these stones. The problem is that lithium is hard to find and this process made ​​it very expensive, after all, much work is needed to be able to extract a few pounds of metal.
