How an accidental discovery made this year could change the world
On the surface, lithium-sulfur seems to solve all of lithium-ion’s problems. It uses far less ecologically harmful materials, can be cheaper to produce, can be up to three times more energy-dense (meaning a lighter battery) and is far less likely to catch fire. All without compromising charge speeds.
I don't endorse the breathlessness of this article but it is factual.
