Comments on: A Battery That Breathes Air! Too Good To Be True? http://gigaom.com/2011/04/27/a-battery-that-breathes-air-too-good-to-be-true/ Thu, 20 Jun 2013 07:25:39 +0000 hourly 1 http://wordpress.com/ By: scott http://gigaom.com/2011/04/27/a-battery-that-breathes-air-too-good-to-be-true/#comment-620703 Sat, 30 Apr 2011 17:54:01 +0000 http://gigaom.com/?p=336710#comment-620703 Thanks, but I don’t have access and the subscription cost appears too much for casual interest. Not sure how much I’d understand anyways; I have a science education but am certainly no battery expert.

Regardless, your article was refreshing for someone who’s always been interested in green science. The internet is awash with articles that trumpet the news of any and all developing technologies. Unfortunately these same articles are so devoid of context (like required breakthroughs, economics, timeline, etc) that the reader is left with little clue about the technology’s true potential. You answered a few of my questions about Li-Air.

It is pretty technical and I did not want to get into that in this post. If you are interested, below is a link to a journal article that does a great job of laying all this out. You can then decide if it really is 5 breakthroughs or (as one of my colleagues put it) “somewhere between 4 and 10″.

You will need access to the journals.

But this is missing the point. The blog post is not about going ga ga about anything or putting down anything. I’m more optimistic than pessimistic about the technology, but that is besides the point.

It is a (in my opinion) objective look at a technology to see where we are in the process of innovation. Are we at a point where scaling up is the issue or are we still looking at technological breakthrough? or are we still dealing with some fundamental questions?

I will read the book though. Sounds interesting

In my previous post I alluded to improvements in anodes and cathodes for Li-ion batteries. If these are commercialized, then we are talking about a doubling of energy density compared to where we are today. That is pretty amazing. Think about this: 15 years ago we had a battery at 1/2 the energy density of today’s batteries. The cycle life of many Li-ion batteries today is >1000 while it was 200-300 a decade ago. If we can double from where we are then a lot can happen.

a book recommendation for you:

We need better batteries to improve electric cars range and recharging speed. I believe that EVs are the future of mobility and batteries are the single most important part of it.
