Abstract: A non-aqueous electrolyte secondary battery can efficiently discharge a gas generated to the outside of an electrode and exhibits a low decrease in battery capacity even when used for a long period of time in the case of using an aqueous binder as a binder of a negative electrode active material. The non-aqueous electrolyte secondary battery includes a negative electrode active material layer on the surface of a negative electrode current collector, in which the negative electrode active material layer contains an aqueous binder, a highly porous layer having a porosity that is higher than that of the separator is provided between the negative electrode active material layer and the separator, the porosity of the highly porous layer being from 50 to 90%, and a ratio of a thickness of the highly porous layer to a thickness of the negative electrode active material layer being from 0.01 to 0.4.

Abstract: A non-aqueous electrolyte secondary battery enables a reaction for forming a film (SEI) on a surface of a negative electrode active material to proceed more uniformly when an aqueous binder is used as a binder for a negative electrode active material. The non-aqueous electrolyte secondary battery has a positive electrode active material layer formed on a positive electrode current collector, a negative electrode active material layer containing an aqueous binder formed on a surface of a negative electrode current collector, and a separator holding an electrolyte solution, wherein the ratio value of a volume of a residual space inside the outer casing to a volume of pores of the power generating element is 0.4 to 0.5, and the ratio value of a volume L of the electrolyte solution injected to the outer casing to the volume of the residual space inside the outer casing is 0.6 to 0.8.

Abstract: There is provided a negative electrode for a lithium-ion secondary battery, including a conductive substrate, a negative electrode active material layer containing a negative electrode active material capable of absorbing and desorbing lithium ions and a conductive member having a lower elastic modulus than that of the conductive substrate, wherein at least part of the negative electrode active material is connected to the conductive substrate via the conductive member. There is also provided a lithium-ion secondary battery with such a negative electrode.

Abstract: A female mold (2, 12, 22, 32, 42, 52, 62) having a desirable pattern is formed on a substrate (1, 11, 21, 31, 41, 51, 61). Next, ceramic material (3, 13, 23, 33, 43, 53, 63) is filled in spaces in the female mold. Thereafter, the female mold is removed by heating the entire substrate, whereby a desirable thick film pattern can be finely and easily formed. The inorganic paste material comprising inorganic liquid vehicle containing water glass as main ingredient and powdery solid dispersed in the inorganic liquid vehicle is used as the ceramic material. The volume change of the inorganic paste material is small during the drying and calcinating processes, thus the inorganic paste material is prevented from being broken.
