Abstract: A method of producing an electrode including decreasing a yield stress of a slurry containing an active material to two-thirds or less, and applying the slurry to a current collector.

Abstract: A nonaqueous electrolyte battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. At least one of the positive electrode and the negative electrode comprises a current collector made of aluminum or an aluminum alloy and an active material layer laminated on the current collector. The active material layer contains first active material particles having an average particle diameter of 1 ?m or less and a lithium diffusion coefficient of 1×10?9 cm2/sec or less at 20° C., and second active material particles having an average particle diameter of 2 to 50 ?m. A true density of the second active material particles is larger by 0.01 to 2.5 g/cm3 than a true density of the first active material particles.

Abstract: A nonaqueous electrolyte battery includes a positive electrode, a negative electrode, a separator and a nonaqueous electrolyte. The negative electrode contains a negative electrode active material having a Lithium ion insertion potential of 0.4 V (vs. Li/Li+) or more. The separator is provided between the positive electrode and the negative electrode. The separator has a porosity of 50% or more and a pore diameter distribution in which a median diameter is larger than a mode diameter. The porosity and the pore diameter distribution are measured by mercury porosimetry. A surface roughness of the negative electrode is larger than the mode diameter.

Abstract: A nonaqueous electrolyte battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. The negative electrode contains a negative electrode active material. The negative electrode active material has a lithium ion insertion potential of 0.4V (vs. Li/Li+) or higher and a pore diameter distribution in which a median diameter is not smaller than 1 ?m and a mode diameter is not larger than 1/10 of the median diameter. The pore diameter distribution is measured by mercury porosimetry.
