An electric car future is speeding closer – economic
analysts project that a third of all automobiles could be
battery-powered by 2040. Most of these vehicles
(22)---- large lithium batteries, which prompts worries
about whether the world’s lithium supply can keep up.
(23)----, another element, cobalt, is a bigger concern.
The best lithium battery cathodes (negative electrodes)
all contain cobalt, and its production is limited. Even with
a very conservative estimate of 10 million electric
vehicles (EVs) in 2025, the demand (24)---- cobalt that
year could reach 330,000 metric tons, whereas the
available supply at that time would be at most 290,000
metric tons. Recycling lithium batteries is complicated
and rarely done. Even with higher rates and cheaper
processes, recycling (25)---- the use of lithium batteries
until 10 or more years after mass-market penetration of
EVs. But newer cathode chemistries offer hope.
(26)---- recently developed nickel-rich and cobalt-free
formulations, cobalt demand may decline.
