ELECTRODE MATERIAL, PASTE FOR ELECTRODES, AND LITHIUM ION BATTERY

摘要

An electrode material in which an electrode active material having a carbonaceous film formed on the surface is used and which is capable of suppressing a voltage drop when high-speed charge and discharge is carried out in a low-temperature environment is provided.;A electrode material, wherein the electrode material have a particulate shape, the electrode material is formed a carbonaceous film on surfaces of electrode active material particles, and the carbonaceous film is constituted randomly stacking graphene layers. Preferably, an inflection ratio of a lithium ion migration path in the carbonaceous film in the electrode material is in a range of 1.1 to 100.
