摘要： A nonaqueous electrolyte battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. The negative electrode contains a lithium compound and a negative electrode current collector supporting the lithium compound. A log differential intrusion curve obtained when a pore size diameter of the negative electrode is measured by mercury porosimetry has a peak in a pore size diameter range of 0.03 to 0.2 μm and attenuates with a decrease in pore size diameter from an apex of the peak. A specific surface area (excluding a weight of the negative electrode current collector) of pores of the negative electrode found by mercury porosimetry is 6 to 100 m2/g. A ratio of a volume of pores having a pore size diameter of 0.05 μm or less to a total pore volume is 20% or more.

摘要： An electrode for a non-aqueous electrolyte battery includes a current collector formed of aluminum foil or aluminum alloy foil, and an active material-containing layer formed on a surface of the current collector and containing an active material, a conductive agent and a binder. The conductive agent comprises a carbon particle group containing first carbon particles each exhibiting an aspect ratio of more than one. A portion of each of the first carbon particles is embedded into the current collector to the depth corresponding to 20 to 50% of the thickness of the current collector. A major axis of each of the first carbon particles has a length of 1.05 to 1.50 times as large as the thickness of the active material-containing layer.
