From the following site we see that the term "Li-Ion battery" is actually rather generic:
My question is this: Which chemistry addressed above is the one used in the Sanyo UR14500P cell (used in Zebralight's ZL584 584 mAh 14500 battery) and in the Panasonic NCR18650A cells (used in the Redilast 3400 mAh 18650 battery) as seen on the IlluminationSupply.com website, for example? Presumably, this would be the same chemistry in most all the 14500 and 18650 batteries most typically discussed on CPF. Is that correct?
Thanks for helping me get it straight.
