Abstract
(EN)
One embodiment of the present invention provides an electrode group. The electrode group includes a positive electrode, a negative electrode comprising a lithium-titanium composite oxide, and a separator arranged at least between the positive electrode and the negative electrode. The separator comprises fibers. The permeability of the separator is 10-20%. The separator is a porous fiber sheet comprising fibers and pores in which the pore area is 8×10-9 m2 or more.
