Lithium-metal batteries

Lithium quantified, dead or alive

Lithium-metal batteries offer great energy density improvement over lithium-ion, but understanding their cyclability is a daunting task. Now, an analytical method is reported to quantify lithium in its electrochemically inactive and active forms, enabling insights about the anode reversibility throughout cycling.
