A disruptive shadow looms over Tesla Motors’ giant Nevada “gigafactory”—the threat of rapidly advancing battery technology. While plenty of hurdles face new battery tech, the emergence of a viable and significantly better battery in the next five years could turn Tesla’s $5 billion facility for mass producing lithium-ion batteries into a giga-albatross.
In January, Fuji Pigment Co. Ltd. (not affiliated with Fujifilm) announced that it had made a significant breakthrough in aluminum-air battery technology. Aluminium-air batteries have a theoretical capacity more than 40 times greater than the lithium-ion cells Tesla will soon mass-produce, and Fuji Pigment has stated it will commercialize its innovation by the end of 2015. This means that the gigafactory’s products could already be outclassed before its target 2016 opening—and long before the estimated 7-10 years of full production it could take to recoup the factory’s costs.
