Bloomberg: "Producers everywhere have struggled to keep up with demand as electric cars went from almost no sales a decade ago to more than half a million vehicles last year. The battery in a Model S from Musk’s Tesla Inc. uses about 45 kilograms (100 pounds) of lithium carbonate. More mines are planned, but difficulties at Olaroz -- the first new South American lithium mine in two decades -- are limiting funding for new ventures in Argentina, home to the world’s third-largest reserves.
“The uncertainty on the supply side is driving prices up and making investors nervous,” said Daniela Desormeaux, CEO of Santiago-based lithium consulting firm SignumBOX. “We need a new project entering the market every year to satisfy growing demand. If that doesn’t happen, the market will be tight.”"
