The present disclosure relates to a method for analyzing an electrode for a battery, which has the advantage of being capable of more easily distinguishing between the constituent materials of the electrode such as the electrode active material, the conductive material, and the pores, by using scanning spreading resistance microscopy.

Battery electrode analysis method

The disclosed relates to a method for preparing an organic zinc catalyst used in the synthesis of a polyalkylene carbonate resin, an organic zinc catalyst provided therefrom, and a method for preparing a polyalkylene carbonate resin using the catalyst. The organic zinc catalyst according to the present disclosure includes a predetermined amount of Zr on the surface through a simple process, and thus can exhibit improved catalytic activity as compared to a conventional catalyst in the polymerization process for preparing a polyalkylene carbonate resin.

Method for preparing organic zinc catalyst, organic zinc catalyst prepared by the method and method for preparing polyalkylene carbonate resin using the catalyst
