Abstract

Provided is a carbonaceous material capable of enhancing the initial charge and discharge efficiency and the cycle characteristics of lithium ion secondary batteries. The carbonaceous material is used as an electrode material for a lithium ion secondary battery and has a volume resistivity of 0.7 Ω·cm or less as measured at a pressure of 13 MPa in the form of a mixture of 5 wt % of the carbonaceous material and 95 wt % of lithium cobaltate.
