Evaluation od a Negative Electrode Material for a Lithium Ion Battery Using an Immersion Heat Analysis

Abstract

For the evaluation of the chemical properties of the anode active materials for the lithium ion battery, the immersion heat analysis method was studied. The immersion heat is detected when the anode active material like graphite is immersed in organic solvent. The heat value depends on the graphite structure. It was found that the anode active materials were separated in the point of immersion heat.
