In 2021, international gross sales of electrical automobiles will attain 16 million items, highlighting the fast demand, stated the Worldwide Power Company. The transportation power transition has solely simply begun.

Most batteries retired from EVs nonetheless have about 70% of their capability left, says San Diego-based startup Smartville, noting that this makes them a great candidate for second-life use.
