From the header above it tells you that the IRON OXIDE battery is on the way.  As you said Leif the world is full of surprises. Here is a bit of history on that iron oxide. It appears to have a quick recharge rate, holds charge on par of existing batteries for the EV market, cost is extremely much less than the cobalt or any other EV battery presently built for commercial transportation.  Expected much lower cost to produce and below present retail pricetags.  It will not erase the need for cobalt however but sygnificant reduction by multiple 10 of percentiles. the cobalt for some reason hinted that it would be almost as much as an trace element presence in the battery from the RPT that i read very thouroughly.  Not trying to pop bubbles but IRON OXIDE could say move over COBALT!  TRUE!  Either way it is a surprise to me Leif!
