| titleOfInvention | Negative electrode for lithium secondary battery, lithium secondary battery, and method for producing negative electrode for lithium secondary battery |
| abstract | <P>PROBLEM TO BE SOLVED: To make cycle characteristics better through restraint of degradation of electrode energy density of a lithium secondary battery. <P>SOLUTION: The lithium secondary battery 20 is provided with a negative electrode for lithium secondary battery 23 equipped with a negative electrode collector 11 with its surface made coarse, a negative electrode active material layer 12 mainly composed of amorphous silicon and uniformly formed on a surface of the negative electrode collector 11 and a negative electrode binder 13 formed on a surface of the negative electrode active material layer 12. By using the negative electrode collector 11 with its surface coarse, stress concentration in the negative electrode active material layer generated by expansion and contraction of the negative electrode active material accompanying with charging and discharging is alleviated, thus pulverization or peeling of the negative electrode active material layer are restrained. Further, since the negative electrode binder 13 is formed on the surface of the negative electrode active material layer, the negative electrode active material layer is hardly dropped off from the negative electrode collector so as to restrain degradation of conductivity. Moreover, since unnecessary volume part without active material does no exist on the surface of the negative electrode collector 11, degradation of electrode energy density can be restrained. <P>COPYRIGHT: (C)2010,JPO&INPIT |
