1. A method, comprising:
performing 30 cycles of discharging and charging of an electrochemical cell, the electrochemical cell comprising:
a first electrode comprising metallic lithium; and
a second electrode; and
applying, during at least one period of time during the discharging and/or charging, an anisotropic force having a component normal to a surface of the metallic lithium of the first electrode,
wherein, after the 30 cycles of discharging and charging, the first electrode has a porosity of less than or equal to 65%.
