Tesla has their own battery technology. But the chemistry belongs to Panasonic, who creates cells.
You combine cells (like the 18650) together to create batteries. The Gigafactory is trying to make 26650 cells, which should be more efficient in cars than the 18650 cells (which were originally designed for laptops)
Tesla's use of 18650 was highly innovative. They "hacked" growth into their company by taking advantage of the scale and scope of laptop manufacturers. But now that TSLA is one of the largest users of Lithium Ion in the world, they need to come up with a more efficient, car-specific cell design now.
