Abstract
Lithium ion batteries, methods of making the same, and equipment for making the same are provided. In one implementation, a method of fabricating a pre-lithiated electrode is provided. The method comprises disposing a lithium metal target comprising a layer of lithium metal adjacent to a surface of a prefabricated electrode. The method further comprises heating at least one of the lithium metal target and the prefabricated electrode to a temperature less than or equal to 180 degrees Celsius. The method further comprises compressing the lithium metal target and the prefabricated electrode together while applying ultrasound to the lithium metal target to transfer a quantity of lithium from the lithium metal target to the prefabricated electrode.
