Abstract: A lithium ion secondary battery includes a positive electrode, a negative electrode, and an electrolyte provided between the positive electrode and the negative electrode. The positive electrode includes a positive electrode current collector and a positive electrode active material layer over the positive electrode current collector. The positive electrode active material layer includes a plurality of lithium-containing composite oxides each of which is expressed by LiMPO4 (M is one or more of Fe (II), Mn (II), Co (II), and Ni (II)) that is a general formula. The lithium-containing composite oxide is a flat single crystal particle in which the length in the b-axis direction is shorter than each of the lengths in the a-axis direction and the c-axis direction. The lithium-containing composite oxide is provided over the positive electrode current collector so that the b-axis of the single crystal particle intersects with the surface of the positive electrode current collector.

Abstract: To simply manufacture a lithium-containing oxide at lower manufacturing cost. A method for manufacturing a lithium-containing composite oxide expressed by a general formula LiMPO4 (M is one or more of Fe (II), Mn (II), Co (II), and Ni (II)). A solution containing Li and P is formed and then is dripped in a solution containing M (M is one or more of Fe (II), Mn (II), Co (II), and Ni (II)) to form a mixed solution. By a hydrothermal method using the mixed solution, a single crystal particle of a lithium-containing composite oxide expressed by the general formula LiMPO4 (M is one or more of Fe (II), Mn (II), Co (II), and Ni (II)) is manufactured.

Abstract: A protective circuit includes a non-linear element, which includes a gate electrode, a gate insulating layer covering the gate electrode, a pair of first and second wiring layers whose end portions overlap with the gate electrode over the gate insulating layer and in which a second oxide semiconductor layer and a conductive layer are stacked, and a first oxide semiconductor layer which overlaps with at least the gate electrode and which is in contact with the gate insulating layer, side face portions and part of top face portions of the conductive layer and side face portions of the second oxide semiconductor layer in the first wiring layer and the second wiring layer. Over the gate insulating layer, oxide semiconductor layers with different properties are bonded to each other, whereby stable operation can be performed as compared with Schottky junction. Thus, the junction leakage can be decreased and the characteristics of the non-linear element can be improved.
