SECONDARY CELL CONTAINING ORGANIC-INORGANIC HYBRID NANOPOROUS MATERIAL AS WATER ADSORBENT

摘要

The present invention is a secondary cell in which an electrode assembly comprising an anode, a cathode and a separation membrane disposed between the anode and the cathode and an electrolyte are included together inside a cell case, the secondary cell comprising, as a water adsorbent, in at least one of the areas selected from the group consisting of the anode, the cathode, the separation membrane, the electrolyte and the inside of the cell case: a first organic-inorganic hybrid nanoporous material which allows at least 70% of the total amount of adsorbed moisture to be desorbed at 150℃ or below and thus can be regenerated; and optionally a second organic-inorganic hybrid nanoporous material which exhibits greater moisture adsorption capacity than moisture desorption capacity when the relative humidity (p/p0) is 0.3 or lower (p0 represents the saturated vapor pressure at an application temperature, and p represents the vapor pressure at the time of adsorption).
