▎ 摘  要

NOVELTY - Manufacturing electrode material by hydrostatic pressure pressing comprises (i) injecting a sulfur-supported precursor into an elastomer mold; (ii) injecting the elastomer mold filled with the sulfur-supported precursor into a hydrostatic pressurization device, heating the inside of the hydrostatic pressurization device to maintain a reaction temperature; (iii) performing hydrostatic pressurization at the reaction temperature condition in a state in which the inside of the hydrostatic pressurization device is pressurized at a set pressure; and (iv) lowering the internal pressure of the hydrostatic pressure pressurizer and taking out the sulfur-supported precursor from the elastomer mold to obtain an electrode material. USE - The electrode material is useful for a secondary battery (claimed). ADVANTAGE - The method maximizes the loading amount by efficiently supporting sulfur on the surface as well as the inside of a carrier; ensures sulfur can be efficiently supported up to the inside of the carrier; and achieves high efficiency through high energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for electrode material manufactured by above method. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for manufacturing electrode material by hydrostatic pressure pressing (Drawing includes non-English language text).
