ABC-ul chimiei acumulatorilor

[Valahul]

De multe ori vedem diferite tipuri de acumulatori: LI-IO, IMR, INCR, ICR etc.
Ar fi util ca in acest topic sa prezentam in mare ce inseamna, eventual avantajele/dezavantajele fiecaruia.
Incep eu pe scurt:

ICR uses a Lithium cobalt oxide positive electrode.
INR uses a Lithium nickel oxide positive electrode.
IMR uses a Lithium manganese oxide positive electrode.
ICR and INR is nearly equal and IMR is usual higher current, but manufacturers thinkers with the exact chemical formula to improve the batteries and this Samsung looks like a very successful high power battery.
Si de pe un forum ceva interesant:
R-lsales Samsung INR18650-20R vs FT Sony 10A 18650
Samsung 20R 18650 about 4 days old.
Sony 10A 18650 about 2 weeks old.

Atty is Trident 0.6 ohm quad coil.
Device is china junk with hot spring.

Voltage with 0.6 ohm load:
Samsung 20R = 3.86v
Sony 10A = 3.65v

No load voltage after load test:
Samsung 20R = 4.2v
Sony 10A = 4.19 v

Voltage drop:
Samsung 20R = 0.34v
Sony 10A = 0.54V

The Samsung 20R performs well from 1 amp to sub-ohm high amps; nice batt
