When is news not news?

October 29, 2010

I started thinking about this after being given a job by my friends at Chemistry World. The paper seemed quite cool and speaking with the author about it really enthused me, but then I spoke to another expert on the field and my enthusiasm was somewhat dampened.

I still think the paper and the idea in it is pretty cool – solve the problem of electrolyte migration in Li ion batteries by tethering the electrolytes. This makes better batteries that can last for longer and are safer than conventional Li ion batteries. Li ion batteries can hold a lot more charge than other sorts of batteries so working with them could be a good idea. Although no-one here has addressed the problem that Li resources may be running out so how do we make the batteries then? I guess that’s someone else’s problem.

The issue pointed out by the other expert is that only part of the electrolyte is tethered. Oh yes and apparently they’ve only tested the system at between 100th to 1000th of the operation current of a real Li ion battery. Issues that may have been easily resolved pre-publication with a couple more experiments – but then such is the way of peer review.

My problem was then is this story still worth publishing as news? I think yes, as it does further science and is a neat new concept, but it certainly doesn’t have the impact that it might have done and a lot of lay-people might not understand that this one experiment cannot really hope to solve all our battery concerns. They might read this and think the advances had already been made, or alternatively read this and think we are still a long way from the perfect battery (which would be true, though we may be closer now than we were).

I liked the concept so I think it is worth bringing to a wider audience, you may not agree. Anyhow the story appeared here so you can judge for yourselves whether it is newsworthy or not.
