@apresher – I don't think the battery manufacturers would provide a service agreement to protect against catastrophe. It's not that they can't do that but simply they don't want to take the burden. I am using a Toyota Prius Hybrid but didn't get such service agreement.

@davetrowbridge – It sounds interesting, we a re all looking for ways to reduce the cost on these systems. As technology develops I'm sure there should be an affordable way to do the same thing in a different way.

@Charles – It could be a miracle if it could be done, it would definitely reduce the price of a hybrid vehicle making it more affordable. Most of the users are afraid to by a hybrid due to the battery replacement cost.

@Charles - I wonder why they decide the durability of the battery in miles, why not in years. Does cheap material again reduce the durability / life of the battery?

@Greg –yes as you said I wonder if these batteries will last that long. Is this just to make the sale or does the battery actually stay alive for this number of years?

 @Greg -  I didn't know that the operating temperature affects the battery life. If so have the battery manufacturers looked at taking necessary steps to maintain the required temperature?

I agree with you. I'm very skeptical on the longevity of he batery. I cange my Ion-Lithium phone batteries once per year, and I'm sure my pocket is not as hot as an engine.

Yeah, I'm with you too.  Well made cells, carefully packaged, handled with the utmost of care MAY last a good long time.  Our experiences with secondary cells in the 700 A-hr range are that the manufacturers turn out really good cells at the beginning when you are qualifying the cells.  Later as you get into a high-rate production, the quality of the cells "normalizes" and you start seeing more issues with the cells. 

If the care of the battery requires any prudent use and thought by the consumer, forget it.  The battery designers need to think in terms of dumb and dumber.

Cells produced by the hundreds of thousands should be consistent in their performance (good but not stellar), but I think the researcher presenting his findings may have been into the New Riders of the Purple Sage stuff.

Charles, great article.  Thanks for this.  I've made sure to share it with folks on my website as well.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet.

NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
