Abstract
There is provided a negative electrode for a lithium-ion secondary battery, including a conductive substrate, a negative electrode active material layer containing a negative electrode active material capable of absorbing and desorbing lithium ions and a conductive member having a lower elastic modulus than that of the conductive substrate, wherein at least part of the negative electrode active material is connected to the conductive substrate via the conductive member. There is also provided a lithium-ion secondary battery with such a negative electrode.
