1. An impact-resistant, lightweight, EMI-shielding electric vehicle battery enclosure comprising:
a housing comprising a multiple-layer fiber-metal laminate including:
at least one fiber-reinforced thermoplastic polymer composite layer formed by vacuum assisted resin injection;
a first oleophilic electrochemically surface-roughened metal layer having a thickness from approximately 0.1 mm to 5 mm positioned on a first side of the at least one fiber-reinforced thermoplastic polymer composite layer, wherein the first oleophilic electrochemically surface-roughened metal layer has a liquid thermoplastic resin contact angle of approximately 20 degrees;
a second oleophilic electrochemically surface-roughened metal layer having a thickness from approximately 0.1 mm to 5 mm positioned on a second side of the at least one fiber-reinforced thermoplastic polymer composite layer, wherein the second oleophilic electrochemically surface-roughened metal layer has a liquid thermoplastic resin contact angle of approximately 20 degrees;
an insulating fiber-reinforced polymer composite positioned between the at least one fiber-reinforced thermoplastic polymer composite layer and either the first or second oleophilic surface-roughened metal layer;
a layer of impact-absorbing foam selected from one or more of polyurethane, polystyrene, polypropylene, polyvinyl chloride, or polyethylene;
wherein the housing includes reinforcing ribs;
wherein the multiple-layer fiber-metal laminate has a stiffness-to-weight ratio of at least 30 GPa/(g/cm3); and
a detachable cover positioned over the housing.
