To provide an electric storage device that has excellent charging characteristics, particularly at a low temperature. Provided is a nonaqueous solvent-based electric storage device containing as positive electrode active materials, at least one of a lithium nickel aluminum complex oxides and a spinel-type lithium manganese oxide active material having LiMn

There is provided a positive electrode active material for lithium secondary batteries which suppresses gelation when kneaded with a binder resin in producing a positive electrode material and provides excellent coating properties. The positive electrode active material for lithium secondary batteries comprises a lithium composite oxide represented by the following general formula (1) and a Ca atom contained in the lithium composite oxide. When the positive electrode active material is analyzed by X-ray diffraction using CuK radiation as a radiation source, the intensity ratio (b/a) of (b) the diffraction peak at 2=18.70.2 to (a) the diffraction peak at 2=37.40.2 derived from CaO is from 10 to 150.

Provided is a beta-type zeolite which has a high catalytic activity and is not easily deactivated. The beta-type zeolite of the invention has a substantially octahedral shape, has a Si/Al ratio of 5 or more, and is a proton-type zeolite. The Si/Al ratio is preferably 40 or more. This beta-type zeolite is preferably obtained by transforming a raw material beta-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the beta-type zeolite to water vapor, and subjecting the exposed beta-type zeolite to an acid treatment.
