Claims18
An article for inclusion in an electrchemical cell, comprising:
- a layer comprising lithium metal;
- and
- a passivating layer disposed directly on the layer comprising lithium metal, wherein the passivating layer comprises boron, phosphorus, antimony, selenium, tellurium, hydrogen, and/or a halogen,
- wherein the passivating layer comprises a reaction product of lithium metal from the layer comprising lithium metal and a gas reactive therewith,
- wherein the passivating layer comprises irregular structures that anisotropically extend away from the layer comprising lithium metal,
- wherein the passivating layer comprises open pores,
- wherein the passivating layer has a porosity of greater than or equal to 5%, the passivating layer has a lightness of greater than or equal to 20 and less than or equal to 65,
- wherein the layer comprising lithium metal has an Rz value of between 1 micron and 10 microns, and
- wherein the layer comprising lithium metal comprises at least 95 wt % lithium.
