The Electrochemical properties of Lithium ion Secondary Battery using Ag-deposited graphite anode

은 담지한 혹연을 부극 활물질로 이용한 Li ion 2차전지의 전기화학적 특성 연구

New Ag-deposited graphite anodes were developed using wet chemical reduction methods for depositing Ag metal onto graphite particles. In this paper, we investigated X-ray diffraction pattern and charge-discharge behavior for Ag-deposited graphite anode. The Lithium ion cello using Ag-deposited graphite anode showed a high average discharge voltage of 3.6∼3.W and a excellent cycle ability than that of conventional graphite. Little capacity loss in this battery may be due to the highly durable Ag-deposited graphite anodes.
