METALLIC PASTE COMPOSITION FOR FORMATION OF AN ELECTRODE COMPRISING AG-COATED POWDERS AND ELECTRODES USING THE SAME

摘要

PURPOSE: A metallic paste composition for forming an electrode is provided to prevent degradation of electrical performance and physical performance regardless of decreasing silver content. CONSTITUTION: A metallic paste composition for forming an electrode comprises 20-60 wt% of plate type silver powder(100); 0.1-25 wt% of plate type copper, nickel, or aluminum powder(200) coated with the silver; 5-20 wt% of organic vehicles; and 10-60 wt% of solvent. The silver powder has an average particle size of 5-20 um and a thickness of 500 nm or less. The copper, nickel, or aluminum powder has an average particle size of 5-30 um and a thickness of 1 um or less.
