Xtalic provides nanostructured aluminum alloys, called nano-Al, with potential applications in the Li-ion battery industry. Continuously driven to develop thinner and lighter batteries, the demand to innovate with lightweight materials is strong. Our nano-Al alloys have tensile strengths up to four times greater than traditional commercial aluminum alloys. In addition, our nano-Al electrodeposition manufacturing process produces thin foils much easier than traditional rolling processes.
A potential application of high-strength, thin nano-Al foils is as current collectors in Li-ion batteries. With a tensile strength that is four times higher than conventional aluminum foil, nano-Al is expected to withstand the rigors of battery assembly with dramatically reduced current collector thickness. For example, reducing the current collector thickness by 50% can increase the volumetric energy density of high-energy batteries by up to 4% and of high-power batteries by up to 8%. Using electrodeposition can also reduce defects, improve thickness uniformity and provide a cleaner and more consistent foil surface.
Another potential battery application is the use of nano-Al as the outer protective casing of a cell. Nano-Al sheet, with four times the strength as a conventional aluminum sheet, can be used as the casing material to create a thinner and lighter outer casing without sacrificing strength. Alternatively, our nano-Al alloy technology can also be applied as a coating on the surface of a traditional aluminum substrate to add strength, hardness and abrasion resistance to the outside surface of the casing where the stress is concentrated. In either instance, nano-Al is providing improved protection of the cell without adding weight or thickness.
