Stanford University researchers have discovered a new source of lithium, the main component for modern rechargeable batteries. A pleasant surprise for scientists was the discovery of lithium in the rock erupted from craters of supervolcanoes. Currently, lithium is mined from natural deposits located in Chile and Australia. However, the constant increase in lithium demand requires more and more fossil fuels. According to Thomas Benson, a leading researcher at Stanford University: \With the advent of a new source of lithium (supervolcanoes), lithium production can increase significantly. A supervolcano differs from an ordinary volcano in the volume of rock erupted in one active cycle of a rock. For a supervolcano, this figure is higher than a thousand cubic kilometers. In this erupted rock, much-needed lithium was discovered. Now lithium accumulation can be sought along the Pacific Volcanic Ring of Fire, in the area of which there are over 60 percent of all volcanoes active on Earth. Scientists have analyzed the chemical composition of the rock erupted by volcanoes more than a million years ago, located near the states of Oregon and Nevada. Lithium was found in the breed, which inspires optimism and opens up prospects for the emergence of an almost inexhaustible source of raw materials so important for mankind. Lithium is the basis for rechargeable batteries, which are currently used in almost all areas of human activity – from smartphones to cars. The development of clean energy can now be supported, as lithium deficiency somewhat restrained the pace of advancement of new technologies, in particular, electric cars. At the moment, about 2 million electric vehicles are already registered in the world, which is only 0.2 percent of the total number of cars. However, the growth rate of production is constantly growing – almost all major car manufacturers are developing alternative electric vehicles. For example, by 2019 already Volvo plans to abandon all gasoline engines and switch to hybrid systems.
