Abstract
We employed electrophoretic deposition (EPD) using AC voltage to prepare lithium iron phosphate (LFP) Li-ion battery electrodes with varying the LFP thickness, to compare bulk-limited electro chemical reaction with the surface-limited electrochemical reactions. We analyzed the electrochemical performances of the thin and thick LFP electrodes at various scan rates. They.....

DOI:
https://doi.org/10.3365/KJMM.2022.60.7.523
Abstract
Unlike conventional solid oxide fuel cells (SOFCs) where ceramic materials have been used as a support, in this study a new SOFC structure with a metal support and a contact layer between the support and anode is suggested. A mixture of Ni-Fe alloy and zirconia ceramics as the contact layer.....

Abstract
A novel magnesium (Mg) production process utilizing an electrolytic method was investigated for the direct reduction of magnesium oxide (MgO). Electrolysis of MgO was carried out with an applied voltage of 3.0 V using a copper (Cu), silver (Ag), or tin (Sn) cathode and carbon (C) or platinum (Pt) anode.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.6.360
Abstract
Li(Ni1-x-yCoxMny)O2 (NCM) materials, which are the cathode active material for lithium ion batteries, have been developed and widely used as an alternative to lithium cobalt oxide, because of the high cost of cobalt. To synthesize high quality NCM materials, it is important to control the process manufacturing of the NCM.....
