Recently, Nanjing University of Science and Technology came in the news that the Xia Hui, the Grand Hui, the Grand Hui Trichtan Institute, has created a preparation method of three-dimensional nanowe electrodes in China, and supply new ideas and new methods for the construction of three-dimensional microdes. Recently, relevant papers published in "Nature - Asian Materials". According to Xia Hui, different from ordinary lithium-ion batteries, micro-cells are seminated in the form of a film, and the thickness of the entire battery is only 10 ~ 20 microns, and is designed to be integrated in an IC card circuit, which can be recycled.
Ten thousand times, no traditional lithium-ion battery explosion risk. Thin film microbattery can be applied to super smart cards, there is also broad application prospects on microelectronic mechanical systems, implantable medical devices, micro-sensors, and micro technology equipment. Compared with the two-dimensional microwate, the design of the three-dimensional microned cell structure utilizes the space height to achieve high energy density and power density of the unit area, and is the research hotspot of the current microelectronic device micro power supply.
However, the positive electrode material constructing self-supporting three-dimensional nano structure is still the difficulty of research. Xia Hui Tips Group designed a two-step hydrothermal synthesis method, successfully prepared from supporting LiCoO2 nanowire arrays on the metal substrate. The nanowire array is connected by a LicoO2 grain having a nanometer, exhibiting a unique "chain" structure, with large surface area and fast ion transmission performance.
