MANUFACTURING METHOD OF HIGH POROUS LITHIUM MANGANESE OXIDE BASED EPOXY SPHERICAL COMPOSITE USING A TEMPLATE CARBONIZATION AND A SPRAY-DRYING METHOD CAPABLE OF IMPROVING ELECTRICAL ADSORPTION AND DESORPTION

摘要

PURPOSE: A manufacturing method of high porous lithium manganese oxide based epoxy spherical composite using a template carbonization and a spray-drying method are provided to synthesize lithium manganese oxide having low-density, large specific surface area, and high porosity.;CONSTITUTION: A manufacturing method of lithium manganese oxide based epoxy spherical composite comprises the following steps: mixing a binder resin composition with an inorganic compound; spraying the mixture on a fluorinated plate and manufacturing a spherical shaped composite by heat-treating; and acid processing the spherical shaped composite. The lithium manganese oxide based spherical shaped composite has a specific surface area of 40-60m^2/g and a pore volume range of 0.20-0. 40cm^3/g. The heating is processed at 450-520 deg. Celsius for 3-6 hours. In the mixing step, the binder resin composition comprises 5-15 parts by weight of imidazole based compound and 80-100 parts by weight of epoxy resin based on 100.0, parts by weight of phenol type curing agent. 30-70 wt% of solvent is included based on 100.0 wt% of the total weight portion. In the mixing step, the binder resin composition and the inorganic compound are mixed at a weight ratio of 1:1-3:1.;COPYRIGHT KIPO 2012
