Li-Ion VS Li-Polymer batteries?

Question

Rechargeable batteries

There are two Mi-Wi devices: E583C and E585.
One Li-Ion 1400mAh, the other 1500mAh Li-Polymer.
What type of battery is more practical?
Thanks

Answer 1

In general, we are being deceived when they write Li-Pol on household batteries:

Developments in the field of polymer electrolytes have made it possible to create a solid electrolyte that conducts lithium ions through the ion exchange mechanism inside the electrolyte matrix. Such an electrolyte made it possible to bring dead batteries with lithium metal electrodes back to life.
A solid electrolyte creates a surface at the point of contact with metallic lithium that prevents the formation of lithium dendrites during cycling, which makes it possible to forget about the main problem leading to fire and explosion of lithium batteries.
As always, there was a good admixture of tar in the honey barrel - lithium-polymer batteries can only work at temperatures above 40 degrees Celsius (since the ionic conductivity of a solid electrolyte at room temperature is negligible). The need for a high operating temperature dictates the need for a battery heating system - so you can not believe the manufacturers proudly labeling their mobile phone batteries as "Li-Pol" (in fact, this is a lithium-ion battery with a polymer electrolyte).

Answer 2

Lithium-polymer ones seem to be less prone to capacity loss when strongly discharged, and so they are almost identical.

Answer 3

I had an Alcatel OT715 phone with a Li-Polymer battery for a very long time, it lived for 6 years, then it swelled up and very strongly. I replaced the Chinese Li-ion and did not live for half a year - it was blown away, pardon the pun.
