One of the most compelling and important advantages of switching our fleet to plug-in electric cars like the Chevy Volt is being able to break this countries dependence on foreign oil. As oil supplies become tighter and demand increases the detrimental effects on economy and quality of life become clear, as the current oil price crisis reminds us.
However, as a new article point out, the Chevy Volt depends on batteries that are produced and assembled in Asian countries and are purchased from Asian countries. Depending on which pack maker GM chooses for the Volt, its batteries will be made either in Korea or China.
When lithium-ion batteries were first developed, the Japanese firm Sony licensed the technology, as well Asian governments have considered building advanced batteries a national priority and have greatly funded the development of a vast production infrastructure.
Although some of the engineering and component assembly for the Volts battery packs will occur in the U.S., both Compact Power and A123 are U.S. firms, there is only one U.S. company that both designs and assembles lithium-ion battery packs here and that’s Indiana-based EnerDel.
EnerDel has a contract to make packs for Norwegian automaker Th!nk and has recently demonstrated a functional 26kWh pack in a vehicle.
It is estimated that the Volts battery pack will "likely will cost more than $10,000 per vehicle," and this concerns US automakers who are forced to shop for the most expense part of their new technology cars from Asian manufacturers. Toyota has their own joint battery venture Matsushita Electric to produce advanced batteries.
There are also some experts who believe the world’s lithium supply might be insufficient for widespread automotive use, but that assertion remains controversial.
So although we may narrowly be able to escape the impending doom of dependence on Middle East oil, will we be simply substituting for a similar problem of dependence on Asian batteries?
