The development of efficient batteries was clearly a contributing factor. Even the early hand held devices indicated that more power was needed for longer periods of time. The Li-ion technology proved to be the most promising technology, so it got a lot of investment. There are other technologies still waiting for maturity and funding for the next generation. My only concern is the disposal of the Li devices. Though we could mitigate that problem with an active recycling campaign. Just a thought.

John Goodenough is NOT a Mechanical Engr. as claimed by the blurb for this article. He is a Physicist who happens to be parked at the Mech E Dept of UT at present.

Just a thought. Can we pack some material alongside the Li-ion batteries which can convert the chemical inside the battery to some kind of a harmless salt at the end of its life. Just have some mechanism to puncture it into the main battery system when it is to be thrown away.

Li-ion technology has been good-enough for now (sorry could not resist that). But this technology has been around for quite sometime now. Other than incremental improvements is there any other chemical technology that improves the energy stored/cu-in dramatically.
