Rewritten article 2014-06[edit]

As of today, I have basically rewritten the article. It describes mostly the "LiPo" cells, which are nothing more than the "lithium-ion" cells in the pouch format. Any reference which basically comes from radio-controlled hobbyists' websites is unacceptable, in my opinion.

I still think we need an article called

which correctly describes the lithium-ion batteries that don't have liquid electrolyte, but use a kind of plastic ionic conductor.

I have done serious academic research on Li-ion, but these other "polymer-electrolyte" batteries are a different topic, which requires input from a real expert. As far as I know, the latter cells are still a matter of research and not widely commercialised, but I don't discard concrete products, especially in niche sectors.---- (talk) 11:28, 26 June 2014 (UTC)

Just for reference, the matter of "true" polymer vs. "wrongly-called" polymer lithium batteries has been discussed in the past. Please see the archive pages:
Some of those discussions were made from 2009 to 2013, reflecting the state of the article at that time, however the general idea is still valid. Overall my feelings are:

Of the options presented, I strongly prefer the very first. I do question the state of the industry though; is there enough actual research ongoing to suggest a separate article? Or is this one of many (many) potential improvements that may or may not make it to production? That's a fine line, obviously, but one worth considering.

Yes, I think there is enough actual research. See the answer of (User talk: 18:48, 4 October 2015 (UTC) ---- (talk) 10:14, 21 January 2016 (UTC)

I just added the Bolloré Bluecar as an example of industrial application, and it turns out that it is a "real" lithium polymer battery with dry electrolyte. And looking at the other applications, I'm not at all sure that the distinction explained at the beginning of the article is relevant anymore. The following phrase is particularly confusing : "While the design is usually flat, and lightweight, it is not a true polymer cell, as the electrolyte is still in liquid form, albeit it may be "plasticized" or "gelled" through a polymer additive". If the electrolyte is liquid it's not lithium polymer battery if it is "gelled through a polymer additive" then it's probably a lithium polymer battery. (talk) 18:48, 4 October 2015 (UTC)

Actually, this is exactly what I meant. As far as I know, the Bollore cells are the only commercially available "real" polymer cells with significant impact. I don't know of any other examples. This is good for the industry but still presents confusion for the article. The fact remains that most users of batteries still think of the "lithium-polymer" batteries as the "flat" batteries for radio-controlled devices. By the way, the amount of "polymer" in the cells is not nearly enough to make them "gelled". Polymers exist in many substances and combinations of them, but that does not mean we should actively encourage adding the adjective polymer to the finished product. I think with the commercialisation of the Bollore cells it is even more important to have two separate articles, one for the "real" polymer cell (with the Bollore cells included), and one explaining the misnomer, and pointing to the lithium ion article.---- (talk) 10:14, 21 January 2016 (UTC)
People writing about lithium polymer batteries seem to be referring to the gelled polymer electrolyte. Nobody calls them "polymer" because they come in a plastic bag. Distinguish between solid and gel electolytes. --Wtshymanski (talk) 15:17, 7 March 2017 (UTC)
