According to one embodiment, provided is a nonaqueous electrolyte battery that includes a positive electrode, a negative electrode, a separator, and a nonaqueous electrolyte. The separator is disposed between the positive electrode and the negative electrode. The separator includes a fiber-made nonwoven fabric having a tortuosity of 1.8 to 3 and a vacancy of 40% to 60%. The negative electrode has an operating potential of 0.7 V or more with respect to the potential of metallic lithium.

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.
