<P>PROBLEM TO BE SOLVED: To provide a negative electrode material and a negative electrode, capable of composing a lithium-ion secondary battery having a high charge/discharge efficiency and an excellent safety at a high temperature, and to provide a lithium-ion secondary battery equipped with the negative electrode. <P>SOLUTION: The negative electrode material contains a carbon material and a fluororesin and when a total of the carbon material and the fluororesin is 100 mass%, the fluororesin content is 0.5-10 mass% and at least a part of the fluororesin is deposited on a surface of the carbon material. The negative electrode for the lithium-ion secondary battery is provided on a surface of a collector with a negative electrode mixture layer formed with the negative electrode mixture containing styrene butadiene rubber or carboxymethyl cellulose as a binder, and the lithium-ion secondary battery is equipped with the above negative electrode for the lithium-ion secondary battery. <P>COPYRIGHT: (C)2010,JPO&INPIT |
