Then came the lithium-ion (Li-ion), followed by the lithium-ion polymer (Li-ion polymer). Over the years, however, the NiMH improved and today this chemistry performs well for mobile phones and other applications. In terms of longevity and ruggedness, the NiMH did not perform so well when placed against the NiCd and I was rather blunt about it.
