AI Technical Summary
Existing electrode material reactor vessel molding methods suffer from low molding efficiency and low bulk density, especially the tamping molding and isostatic pressing molding methods, which are both deficient.
A double-sided pressing mold for electrode material reactors, consisting of an inner core and a liner, is designed using a hydraulic press. Pressure is provided by upper and lower pressure rings and the output end of the hydraulic press to achieve efficient pressing of the molded parts. High wear-resistant materials and a demolding structure are combined to improve molding efficiency and bulk density.
Molding efficiency is increased by 3-6 times, bulk density is increased to 2.8 g/cm³, service life is increased by 30%, and optimal porosity and bulk density are achieved under a pressure of 1 t/cm².
