Abstract:
A nanolaminate manufacturing method has been developed for constructing unique devices and materials, such as the anode of a lithium-ion battery. This partial self-assembly method, called Spin-Assisted Layer by Layer (SALbL) features the construction of materials that are essentially stacks of tens to thousands of nanometer-thick layers, or ‘nanolaminates.’ Because the composition of each nanolaminate is controlled independently of preceding or following layers, it is possible to tune the properties of the final material or device. In the present example, work on creating an improved carbonaceous anode for a lithium-ion battery is shown. Different carbon nanomaterials (carbon nanofibers and carbon nanotubes) as well as anode architectures are shown with their effect on the battery properties.
