Tesla Motors Inc (NASDAQ:TSLA) is expected to sell 21,000 Model S sedans this year and up to 40,000 by 2015. At this rate, Tesla Motors could use the entire global supply of 18650 model lithium-ion batteries for the Model S sedans. Every Model S sedan uses 85 kWh battery pack that uses over 7,000 of the cells.
The Model S uses around 2,000 as many cells as a normal laptop battery and those cells are commodity 18650 cylindrical cells. If Tesla Motors Inc (NASDAQ:TSLA) is expected to hit production of 40,000 cars per year, then it would require the whole output of 18650 lithium-ion cells to supply them.
Tesla Motors Inc (NASDAQ:TSLA) realizes that battery supplies could be an issue. This is why they may add Samsung as one of their additional suppliers. Panasonic is currently Tesla’s primary supplier.
