Batteries are mysterious – do read how to reduce their mystery.

“In its latest electric vehicle outlook, BloombergNEF updated its battery chemistry forecasts, which now include sodium-ion batteries accounting for 3% of passenger car market battery demand in 2035 and 30% of battery demand in the two- and three-wheeler segment.

Those sodium-ion batteries, which don’t use lithium, could help displace up to 7% of lithium demand in 2035. While that percentage seems small, it equates to more than half of all the lithium demand last year.”

A team of researchers from the Department of Energy’s Pacific Northwest National Laboratory (PNNL) has made a significant breakthrough in flow battery design using a common food and medicine additive called β-cyclodextrin, derived from starch. The study, published in the journal Joule, reveals that the flow battery maintained its capacity for energy storage and release for over a year of constant cycling.

What makes the batteries so useful is also what can make them risky. “They put a lot of energy into a small little package,” Michael Pecht, a mechanical-engineering professor at the University of Maryland,
