Can anyone confirm that a "graphene-enhanced" battery will be used in the roadster? Stated here: http://www.wantchinatimes.com/news-subclass-cnt.aspx?id=20150104000004&cid=1202 "A big breakthrough was achieved on Dec. 4 when the so-called super battery for electric vehicles which charges in eight minutes due to the graphene polymer technology was released by Spanish company Graphenano and the University of Cordoba in Spain. US electric car company Tesla Motors announced the launch of the Roadster 3.0 on Dec. 26, 2014. The 3.0 version of the car uses graphene in the production of the battery, which increases its energy storage capacity significantly. The battery range improves by 50% which enables the 3.0 version to travel 644 km on one charge, a non-stop drive from San Francisco to Los Angeles, according to Tesla."
