Sound waves travel three times faster through graphene than through steel, meaning material far beyond the impact point can quickly absorb and dissipate its energy – slowing the projectile down and helping prevent its penetration. The rarest stable metal is tantalum. The rarest metal on earth is francium, but it has no practical use because this unstable element has a half-life of a mere 22 minutes. Tesla has agreed to a deal with Magnis Energy Technologies, which makes materials for electric-vehicle batteries, to secure supplies of Graphite. Graphite mining in Sri Lanka has occurred since the Dutch occupation of the country. It is the only country in the world to produce the purest form of Graphite, vein graphite (also known as lump graphite), in commercial quantities, currently accounts for less than 1% of the world graphite production. Global mine production of Graphite was 1,037,000 tonnes in 2021, up 7% compared to the previous year. China is the leading global producer, accounting for 79% of production in 2021. The problem: The increase in demand is running headlong into a supply shortage. By 2030, natural Graphite is projected to have among the largest supply shortfalls of battery materials, with demand outstripping expected supplies by about 1.2 million metric tons, according to Benchmark. In 2022, Turkey had the world's largest reserves of natural Graphite, at approximately 90 million metric tons. Graphene, the layered sheets constituting Graphite, has remarkable physical properties and is one of the most powerful compounds ever discovered. On average, Tesla owners can expect at least 267 miles of range on a single charge of their car's battery. According to CEO Elon Musk, your Tesla batteries are supposed to last 300,000 to 500,000 miles or 1,500 battery cycles. That's around 22 to 37 years for an average person.
