| Abstract Scope |
Lithium-ion batteries (LIBs) are energy storage devices suitable for multiple applications, from portable electronics to electric vehicles. Despite the booming success of LIBs, they still fall short in providing simultaneously high capacity and high charging rates. In order to improve the performance of LIBs, an unconventional approach is to develop a three-dimensional battery with high aspect ratio cathode and anode features. We are developing electrochemical additive manufacturing (AM) techniques based on the localized electrodeposition of Sn, where metal ions are transferred from a nanopipette. Electrodeposition occurs in a liquid meniscus, a droplet that forms between a nanopipette nozzle and a conductive substrate. By utilizing nozzles with dimensions of 150-250 nm, the sub-micrometer-sized Sn nanostructures can be achieved in a layer-by-layer fashion. These advances in 3D microprinting are the key to the successful future realization of 3D batteries with improved performance characteristics. |
