ELECTROCHEMICALLY GROWN ZINC OXIDE LAYER ON CURRENT COLLECTORS FOR MITIGATING GROWTH OF LITHIUM DENDRITES

A method for manufacturing a battery cell includes connecting a current collector to a working electrode; connecting a zinc metal portion to a counter electrode; immersing the current collector and a portion of the working electrode in a liquid; immersing the zinc metal portion and a portion of the counter electrode in the liquid; supplying molecular oxygen into the liquid; and electrochemically coating the current collector with a zinc oxide layer.
