Hello. A bunch of questions... Please move if deserved to 'Power electronics' or else.
Please answer whatever is known but surely known without guesses ? I want to learn it
correctly.
What is the reason for lithium polymer cells swelling ?
age ?
number of cycles of usage ?
spent ?
lack of use ?
overuse ?
heat ?
why a new unused cell can also swell ?
overcharge ?
overdischarge ?
too fast charging ?
too fast discharging ?
improper storage temperature, or at wrong state of charge ?
If pin pierced, vented and sealed like with tape, are they useable ?
any way to prevent the swelling ?
If explode (rupture) with no fire, what ?
can they be used swollen ?
any 'repair' procedure ?
why a spent, old, poor performing lithium cell does not show swelling ?
brands that do or that do not swell ?
chemistries that do or do not swell ?
incomplete charging cycles ?
...add your own...
No, I do not care about the 'battery university' site.
