'Replacement of Lithium secondary batteries' accelerates the commercialization of solid-state batteries A new electrode of solid-state battery, which is attracting the public's attention as a next-generation large-capacity secondary battery, has been developed to draw attention.
Recently, as the market for new large-capacity secondary batteries such as electric vehicles, electric ships, and electric power storage systems is rapidly growing, researches on solid-state batteries that can replace lithium-ion batteries, which are experiencing safety problems such as fire, are actively studied. Previously, the electrodes of all-solid-state batteries could not produce high power at room temperature, so a separate system was required to increase the temperature. However, Professor Oh suggested a new electrode design that can significantly improve the conductivity of the electrode through a joint study with Professor Jo Jae-pil of Ulsan Institute of Science and Technology (UNIST). Professor Oh newly designed an electrode that significantly improves the transport characteristics of electrons and lithium ions between active materials by stacking densely packed primary particle type of positive electrode with active substance of 10 micro (µm) size and cross-coating electrolytes and electric conductors on the surface of the active materials. Professor Oh said, "If the new electrode developed is applied, it is expected to be able to use the solid-state battery without a separate heating system by securing the high-power characteristics of the solid-state battery even at room temperature." The paper containing the results of this study has been published in the International Journal of Energy and Materials, <Advanced Energy Materials> (IF: 25.245). <Pukyong Today> |
Professor Oh Pil-gun ((Dept. of Graphic Arts Information Engineering) at Pukyong National University presented a new electrode design for solid-state batteries that can increase the output of solid-state batteries even at ordinary temperature.
