METHOD OF EVALUATING PRECISION CRYSTAL STRUCTURE OF POSITIVE ELECTRODE MATERIAL FOR LITHIUM BATTERY USING NEUTRON DIFFRACTING METHOD AND MAGNETIC MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a precision structure evaluating method aiming at the development of a lithium secondary battery, especially the development of a positive electrode material appropriate for a lithium secondary battery. SOLUTION: A neutron diffracting method using a high resolution neutron diffracting device and a magnetic measuring method using a super-conducting quantum interferometer are combined to obtain the accurate information related to lithium and oxygen in the structure of the electrode material.
