... or at least, that's what it sounds like to me.

TL, DR: IBM Research has discovered a chemistry for a new battery which does not use heavy metals or other substances with sourcing concerns. The materials for this battery are able to be extracted from seawater, laying the groundwork for less invasive sourcing techniques than current material mining methods. Just as promising as this new battery’s composition is its performance potential. In initial tests, it proved it can be optimized to surpass the capabilities of lithium-ion batteries in a number of individual categories including lower costs, faster charging time, higher power and energy density, strong energy efficiency and low flammability.
Wow.
