How You Age Lithium Metal Batteries Really Matters
Lithium metal batteries undergo rapid calendar aging, which drains the battery even when it''s not being used and reduces its capacity. The battery electrolyte corrodes lithium metal anode particles (top left) or lithium metal filaments that form on the anode during charging (top right). The corrosion creates irregular clumps of a layer called ...
