>> “Salient Energy says its zinc-ion batteries are the solution to all those issues. They use no lithium, no cobalt, and no nickel. The zinc and manganese are obtained from North American sources. Furthermore, the risk of fire is eliminated. The manufacturing process emits 66% fewer greenhouse gas emissions than the process that makes lithium-ion batteries. And oh, yeah, they cost less as well. What’s not to like?”

>That’s all well and good, but the devil could be in the details. For example, a rechargeable energy storage system would be not likeable if it eliminated fire risks but took days to recharge, or lost capacity after only a few dozen charging cycles.

>> Apparently, Salient has that all figured out. The company pledges the same “power, footprint, and service life as lithium-ion based systems.”
