Yes. the easiest way to extend cell-life is to not use the battery.
We have to be careful about facts and theories. We have some facts that the general consensus is that over 60C can damage a lipo and some guys put their batteries in the fridge, and they found that they got longer life than they did with their previous batteries that were not put in the fridge; however, there are a lot of noise factors, so it could be that someone is jumping to conclusions.
I don't see any proof that keeping batteries in the fridge makes them last longer. I don't see anywhere that a lipo suffers damage at 40C. Lipos are improving all the time, so if you used one method for three years, then put your batteries in the fridge for three years, you'd get longer life because of the general improvement in the manufacture of the battery over the three years - nothing to do with the fridge. Anybody else could have stored their batteries standing on their heads, and they would have seen the same improvement. It's only if you do a side-by-side test, with batteries from the same batch, giving them exactly the same usage, that you could draw any meaningful results and conclusions.
Facts are determined by testing a hypothesis or theory. Without testing and investigation our society would stagnate.
Having started using my methods here years ago would disqualify any battery manufacturing improvements being applicable to my battery packs as they would pre-date any manufacturing improvements,
The side by side comparison is what I am trying to encourage others to do. I have never implied that what we do here is applicable to everyone everywhere. as for the side by side comparison others here have done so before they adopted the procedure and some do not bother for all of their batteries but use it on a select few which have had problems in some of their planes.
As for drawing conclusions, I use the procedure based upon experimental results, all I have requested that if others have a problem then perhaps if they tried what I do it might be of some use to them. In addition I even went to the trouble of purchasing batteries from a number of different manufacturers to see if the refrigeration has any serious adverse on some packs whilst it worked with others but there was no such result! All of the batteries behaved and still behave somewhat equally!
Waiting for battery technology to improve is great but does nothing for the issue today when I am flying!
As for your inability to SEE that battery storage in a refrigerator might help increase a battery's life, I invite you to try it for yourself! I offer the same challenge to anyone who has a battery puffing problem and nothing else they try seems to work! Your failure to see something does not mean that it does not exist. As for some storing their batteries in a refrigerator, it is their choice and I applaud their willingness to experiment. If it works for some at all then it is worth consideration by anyone having a similar issue. It would NOT be suitable for everyone but for some it will be a blessing!
Sure it won't work for everyone and I do not expect that it would when some forum users actually need to warm their batteries before they can use them in their aircraft. I do not deride those who heat their batteries even though here such actions would be disastrous for battery life.
I again ask you for any procedure you know of outside the standard handling instructions and cautions for LiPos excluding the waiting for the battery technology to improve. If you know of anything that may be a HELPFUL alternative to refrigeration PLEASE POST IT!
Have fun!
