Why is the energy storage 'bottleneck' so difficult. And how much effort is being channeled into solving it. Would we expect a breakthrough if enough money is thrown at it? Is it a physical problem (laws of physics say it can't be solved) or is it an engineering problem? Gerard Could someone try to elaborate on “the battery problem”?

No, not everyone is using the FePO4 cathode commercialized by A123. There is still a very broad field of materials under development. For example LG Chem and its Compact Power subsidiary - the group expected to pick up the Volt contract - use a lithium manganese <a href="http://en.wikipedia.org/wiki/Spinel" rel="nofollow">spinel</a>. For a relatively readable review, see the UC Davis <a href="http://pubs.its.ucdavis.edu/publication_detail.php?id=1169" rel="nofollow">assessment of electric-vehicle batteries</a> referenced at the top of my TR story.

I'm not sure the anode makes much difference from a weight/volume point of view, although cycle life MAY be much better with Si. Is everyone using FePO4 for the cathode? And are Li bridges still a short-circuit problem? P.S. Note new email address please. Peter: Cui is right: The cathode is THE
