Abstract
According to an embodiment, an electrode is provided. The electrode group includes a stack. The stack includes a positive electrode, a negative electrode or negative electrodes, and separator. Each negative electrode includes a negative electrode current collector and a negative electrode layer provided on the negative electrode current collector. The electrode group satisfies following relational formulae (I) to (III): 10≤a/b≤16 (I); 0.7≤D/E≤1.4 (II); E≤85 (III). Here, the a[mm] is a thickness of the stack. The b[mm] is a thickness of the negative electrode current collector, or is a total thickness of the negative electrode current collectors. The D[μm] is a thickness of the positive electrode. The E[μm] is a thickness of the negative electrode.
