Before I read this article, my understanding of "Lithium Ion" batteries
was rather limited. I had not been aware of the many and varied
chemistries for these batteries and the cost implications with the
amount of cobalt.
From reading this, it appears that the next big step in Lithium Ion
batteries is "NMC", and more specifically the "811" ratio of Nickel,
Manganese, & Cobalt.
Fascinating read for those of you interested:

They are looking at energy density of 300 WH/Kg. By way of comparison,
SLA batteries are in the 40-50 WH/Kg.
