How many years does it take for diamond to turn into graphite

While this process does happen at room temperature, the activation energy of the reaction to convert diamond to Graphite means that at room temperature, it would take about 1 billion years for the diamond-to-graphite conversion of about 1 cm3 1 c m 3 to happen spontaneously. The largest known graphite deposit in the United States is the Graphite Creek deposit in Alaska. Recent industry exploration has identified a measured and indicated resource of more than 10 million metric tons of ore with 7.8 to 8 per cent graphite. Graphite has not been produced in the U.S. since the 1950s. Graphite occurs in the U.S. as disseminated flake graphite deposits and graphite veins. Because of losses in the manufacturing process, it takes over 30 times as much graphite to make the batteries. There are up to 10 kgs of Graphite in the average HEV and up to 70 kgs in an E.V. There is far more in a Tesla Model S. The lithium-ion battery used in electric power vehicles is made of two electrodes — an anode (negative) on one side and a cathode (positive) on the other. Currently, Graphite is the only material that can be used in the anode; there are no substitutes. Silicon has some desirable properties—it stores significant amounts of energy, is very conductive, and is lighter—but there are some challenges with it. So all the workable batteries out there now use Graphite on the anode side, and they will pay for—as we see it—in the foreseeable future.
