The present invention has as its object the provision of a surface-treated sheet for an alkaline secondary battery, which has gas evolution suppressing effect and also has resistance to an alkaline electrolyte solution. A surface-treated sheet 100 of the present invention for an alkaline secondary battery has a base material 10, and a metal layer 20 formed on at least one side of the base material 10. The metal layer 20 includes an alloy layer 20M that contains Ni and Zn, the alloy layer includes a first region 20A in which a proportion of Ni is 60% to 85% based on a total content of Ni and Zn, and the first region 20A has a thickness of 0.15 μm or greater.

Provided are an easy-to-handle primary battery capable of spontaneous power generation and a moisture sensor including the same. The primary battery includes a separator that is disposed between a negative electrode and negative electrode current collector (a negative electrode) and a positive electrode and positive electrode current collector (a positive electrode), and sucks up electrolyte solution by the capillary phenomenon with an exposed portion of the separator 5 exposed from battery casings.

A novel conversion-type rechargeable battery is constructed, the battery using selenium as the cathode material. Preferably, the selenium is coated over the surface of the pores in a mesoporous ion collector such as carbon. A salt of zinc having an organic ion with polar function group is used with the battery, allowing the solvent of the battery to be either organic or aqueous.
