Lithium-Ion Batteries Could be Too Expensive, MIT Team Says | BNET Auto Blog | BNET: "By all appearances, battery-powered cars are ready for prime time. The list of companies planning to introduce new plug-in hybrids and electric battery cars in the next few years is long, and includes General Motors (the Volt and a separate plug-in hybrid), Ford, Toyota, Nissan, Chrysler, Infiniti, Aptera, Tesla (the Model S sedan), Fisker (the Karma plug-in hybrid), BMW, Bright (a plug-in hybrid commercial van), Coda, Wheego and many more.
Almost all of those vehicles will be powered by lithium-ion batteries, because lithium has the best available energy density while being very low weight. But a team at MIT’s department of materials science and engineering, headed by Donald Sadoway, is convinced that lithium is problematic for a number of reasons and is unlikely to carry EVs the extra mile to widespread consumer acceptance."
