This is also accomplished by altering the duty cycle of the charger. I have an R/C battery charger that uses this technology for charging NiCds and if they are cycled properly I've had them last for 15 years.
If this tech is for real, LiPo should be phased out.
The beauty of LiPo is their size and weight advantage. I'm seeing LiPo batteries showing up in the R/C world that are tiny, but give power similar to much larger NiMH and NiCD batteries.
Another thing to consider with NiCd's is the damaging heat may not come from charging. If you live in Phoenix or Yuma you may very well see a significantly shortened battery life just by virtue of being exposed to summer heat. It doesn't take that much heat to do serious harm to NiCads.
Have you heard of Europositron? They have a theoretical approach to developing a rechargable aluminum air battery. It also promises energy density similar to what nanofiber silicon lithium is promising.
I really want a normal sized vehicle with good performance and 500+ mile range that doesn’t run on imported fuel.
