RE:RE:RE:Thanks to @Zinrc for posting this interesting article on ceo Google this and you will get tons of articles including research articles. One problem with measuring battery degradation is that there are no real standards of how to measure it. Things that impact battery degradation include environmental conditions, how much you discharge before recharging, how much you recharge, how quickly you recharge, how quickly you discharge it, etc, etc. An article suggests that "most lithium ion batteries will degrade to 80% of their full capacity between 500 and 2,000 cycles".
in the latest interview, BT stated degradation of top performing 18650 commercial batteries being 11 to 21 percent by their 150th cycle.
The moral of the story is that there is a lot of things to consider when talking about being best in the battery world and all of these matter. Agoracom is learning about batteries from HPQ and therefore is in an easy position to be vowed.
We need to get to a point where some real knowledgeable battery players get their hands on HPQ's product and do their own testing and come up with their own verdict. Depending on the way they test things, the maximum charge of degradation rates may look different. One could say that they don't care what testing is done, the HPQ material should still be better than whatever is out there but the extent may differ. This may matter if the battery players are testing against more advanced materials than 100% graphite anodes.
Sorry if these realities may raise doubts at to just how great HPQs material is. If there was no doubt, I would guess that the share price would be much higher.
