In a laminate-type power storage element, laminated films forming an exterior body are each formed by sandwiching a metal layer between a resin layer and a heat sealing layer. An electrode body includes a positive electrode and a negative electrode disposed opposite to each other across a separator and is enclosed together with a non-aqueous organic electrolyte solution inside the exterior body. Particles included in the positive electrode or negative electrode have a D90 particle size less than or equal to the thickness of the heat sealing layer.

A method of manufacturing a battery electrode material in slurry form to be coated on a sheet-shaped current collector, the battery electrode material containing an electrode active material made of electrolytic manganese dioxide (EMD) and containing an aqueous binder. The method includes, as a process of mixing and kneading raw materials of the battery electrode material by using water as a solvent, mixing the electrode active material; mixing the binder; and mixing a neutralizing agent, the neutralizing agent being lithium hydroxide (LiOH).

A method for preparing cathode material for a lithium primary battery includes an active cathode material and an active anode material. The active cathode material is manganese dioxide, and the active anode material is either one of lithium metal and lithium alloy. The method includes: a first kneading step in which a boron compound and a thickening agent are kneaded with a diluent to prepare a paste made by dissolving the boron compound in the diluent; a second kneading step in which the paste is kneaded with a conductive additive; and a third kneading step in which the paste obtained in the second kneading step is kneaded with the active cathode material and a binder to prepare the cathode material in slurry form.

Disclosed is a superconducting compound which has a structure obtained by partially substituting oxygen ions of a compound, which is represented by the following chemical formula; LnTMOPh [wherein Ln represents at least one element selected from Y and rare earth metal elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), TM represents at least one element selected from transition metal elements (Fe, Ru, Os, Ni, Pd and Pt), and Pn represents at least one element selected from pnictide elements (N, P, As and Sb)] and has a ZrCuSiAs-type crystal structure (space group P4/nmm), with at least one kind of monovalent anion (F, Clor Br). The superconducting compound alternatively has a structure obtained by partially substituting Ln ions of the compound with at least one kind of tetravalent metal ion (Ti, Zr, Hf, C, Si, Ge, Snor Pb) or a structure obtained by partially substituting Ln ions of the compound with at least one kind of divalent metal ion (Mg, Ca, Sror Ba). The Tc of the superconducting compound is controlled in accordance with the ion substitution amount.

A magnetic semiconductor material contains at least one type of transition metals (Mn, Fe, Ru, Re, and Os) having five electrons in the d atomic orbital as a magnetic ion, in which the magnetic semiconductor material exhibits n-type electrical conduction by injection of an electron carrier and p-type electric conduction by injection of a hole carrier. A specific example is a layered oxy-pnictide compound represented by LnMnOPn (wherein Ln is at least one type selected from Y and rare earth elements of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, and Pn is at least one selected from pnicogen elements of N, P, As, Bi, and Sb). A high-sensitivity magnetic sensor, current sensor, or memory device can be made by using a magnetic pn homojunction structure made of thin films composed of the magnetic semiconductor material.

An object of the invention is to provide an oxide thin film which exhibits a widegap or transparency and p-type conductivity although it has heretofore been very difficult to form. The oxide thin film formed on a substrate contains copper oxide and strontium oxide as a main component and exhibits p-type conductivity at a bandgap of at least 2 eV.
