ANALYSIS METHOD OF BORON CONTENTS IN ANODE MATERIALS OF LITHIUM SECONDARY BATTERY

摘要

The present invention provides a method for accurately and quickly quantitatively analyzing the amount of boron in the negative electrode material of a lithium secondary battery. The method of the present invention is a method for quantitatively analyzing boron in the negative electrode material by heating and acid treatment after heating and acid treatment or adding mannitol in a conventional vial to overcome the disadvantage that the exact content of boron is not obtained By using the closed system pretreatment system to acid-treat the anode material in a sealed plastic container, it is possible to accurately and quickly quantify boron in the anode material.
