The Lunar Rover used Silver Zinc cells. It's usually reported that these were primary cells, but they were the same cells used by NASA in rechargable applications, they just didn't bother with any provision to recharge them.
Looking around, available Silver Zinc cells seem to have an energy density of around 130 Wh/Kg, so Lithium have them matched on energy density and well beaten on cycle life. -- Paul Compton www.morini-mania.co.uk www.paulcompton.co.uk (YouTube channel) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
