    摘要: A secondary battery according to the present invention has a current collector and a positive electrode mixture layer that coats the current collector. The positive electrode mixture layer includes a positive electrode active material, an electrically conductive material, and a binder, and the positive electrode active material is constituted by hollow-structure secondary particles formed by the aggregation of a plurality of primary particles of a lithium transition metal oxide and has a through hole penetrating from outside to a hollow portion. In addition, a particle porosity A1 of the positive electrode active material satisfies 2.0(%)≦A1≦70(%). Furthermore, a DBP absorption A2 of the positive electrode active material satisfies 23 (mL/100 g)≦A2. Moreover, the tap density A3 of the positive electrode active material satisfies 1.0 (g/mL)≦A3≦1.9 (g/mL).

    摘要: A photoelectric conversion material is obtained through easy processing from a substance containing silicon oxide, which is inexpensive, imposes no burden on the environment, and is stable, as a component. This material can be used in a photocell and a secondary photocell. Any of synthetic quartz, fused quartz glass, soda-lime glass, non-alkali glass, and borosilicate glass, which are compositions containing silicon oxide, is pulverized, immersed in an aqueous solution of halogen acid, washed with water, and dried. The resultant material is deposited on an electrode plate and this electrode plate is placed in water where an appropriate electrolyte is mixed. This electrode plate is electrically connected to an opposite electrode to provide a photoelectrode. The material may be enclosed in a container, mixed with an organic electrolyte, having an extraction electrode and an opposite electrode, to provide a photocell.
