The realization of new nanoscale materials and structures can enable revolutionary versus evolutionary advances in science and technology. One dimensional nanomaterials, with its considerably beneficiary characteristics, such as larger specific surface area, radial dielectric confinement effect and lateral propagation properties, can be a good candidate for future electrode materials. And when one dimensional materials act as electrode, it represents a promising solution that improving electrode activity with the larger contact areas and shorter distance of Li ions dissociation with each other. Mai group aims at the key point and long ignored issue which is the losing capacity in the electrode materials in the electrochemical area and conducts research about one dimensional oxide electrode materials’ growth, property control, device assembly, and electromotive storage etc., and designs and develops battery devices with only one nanowire, while at the same time elucidate the nature of capacity loss and optimizes the structure and properties by methods like lithiation, layered architecture, scheduled assembly, ion implantation, and synergetic architecture. A series of creative research results has been explored based on this and a fruitful of low cost, high quality one dimensional material flow and phase change and self-assembly methods has come to live.
