 NiMH batteries are a better choice, but are considerably more expensive than lead-acid.Lithium-ion battery powered vehicles such as the Venturi Fetish and the Tesla Roadster have recently demonstrated excellent performance and range, and nevertheless is used in most mass production models launched since December 2010.Expanding on traditional Lithium-ion batteries predominately used in today's battery electric vehicles, is an emerging science that is paving the way to utilize a carbon fiber structure (a vehicle body or chassis in this case) as a structural battery.
