<P>PROBLEM TO BE SOLVED: To provide a negative electrode active material sheet inexpensively, which can be used as it is as a negative electrode for a lithium ion secondary battery. <P>SOLUTION: The negative electrode active material sheet for the lithium ion secondary battery contains carbonaceous particles which store and release lithium ions and a calcining and carbonizing material binding the carbonaceous particles. Preferably, a pore volume per mass of pores with pore diameters in a range of 0.05 to 100 μm, of the negative electrode active material sheet for the lithium ion secondary battery is 0.07 to 0.25 cc/g and a resistivity is 10 mΩ cm or less. <P>COPYRIGHT: (C)2009,JPO&INPIT |
