CARBON-BASED NEGATIVE ELECTRODE MATERIAL AND SECONDARY BATTERY INCLUDING THE NEGATIVE ELECTRODE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a carbon-based negative electrode material which can be used with an electrolyte containing PC as a main ingredient.

SOLUTION: A carbon-based negative electrode material having a graphene layer structure has crystalline and pores. That is, the crystal structure of the carbon-based negative electrode material is more distorted as compared with graphite. Accordingly, interlayer distance of the graphenes constituting the carbon-based material is larger as compared with graphite. It has been confirmed that the negative electrode material can be used for a secondary battery including an electrolyte containing PC as a main ingredient.
