By way of EV World. . . http://www.evworld.com/general.cfm?pageIDENT=greatwesternmineral.cfm Summary: Lithium-ion batteries won't be practical for cars anytime soon because. . . There's not enough lithium production or exploitable resources to meet the demand. Lithium-ion batteries aren't safe, they burst into flames and explode. Lithium-ion batteries can't be recycled, there is no known way to recover lithium from them. As a result, GM and Toyota and other car makers will soon abandon plans to use Li-ion batteries and will stick with proven NiMH technology. Therefore, we should all invest in a major Canadian producer of nickel! My analysis: Lithium is not a rare element, it's actually the 14th most abundant element in the Earth's crust. Production will follow demand. Multiple approaches have already successfully resolved problems with Li-ion safety. Google turns up multiple companies in the business of recycling Li-ion cells and recovering lithium from them. Furthermore. . . Nickel is not such a common element. Nickel prices have been shooting up, providing car makers with a strong incentive to move from NiMH to Li-ion. Furthermore, the major Canadian nickel producer that Resource Investor wants us to put our money into is notorious for the ecological devastation their mining and processing facilities have caused. The whole area has been described as a "moonscape" and was, in fact, used by NASA as a testing ground for Mars landers.
