Description
Summary:Various high-performance anode and cathode materials, such as lithium carbonate, lithium titanate, cobalt oxides, silicon, graphite, germanium, and tin, have been widely investigated in an effort to enhance the energy density storage properties of lithium-ion batteries (LIBs). However, the structural manipulation of anode materials to improve the battery performance remains a challenging issue. In LIBs, optimization of the anode material is a key technology affecting not only the power density but also the lifetime of the device. Here, we introduce a novel method by which to obtain nanostructures for LIB anode application on various surfaces via nanotransfer printing (nTP) process. We used a spark plasma sintering (SPS) process to fabricate a sputter target made of Li<sub>2</sub>CO<sub>3</sub>, which is used as an anode material for LIBs. Using the nTP process, various Li<sub>2</sub>CO<sub>3</sub> nanoscale patterns, such as line, wave, and dot patterns on a SiO<sub>2</sub>/Si substrate, were successfully obtained. Furthermore, we show highly ordered Li<sub>2</sub>CO<sub>3</sub> nanostructures on a variety of substrates, such as Al, Al<sub>2</sub>O<sub>3</sub>, flexible PET, and 2-Hydroxylethyl Methacrylate (HEMA) contact lens substrates. It is expected that the approach demonstrated here can provide new pathway to generate many other designable structures of various LIB anode materials.
