摘要： The state of a polysilicon film formed by excimer laser annealing an amorphous silicon film is to be evaluated. When the amorphous silicon film is annealed to form a polysilicon film, linearity or periodicity presents itself in the spatial structure of the film surface of the polysilicon film formed depending on the energy applied to the amorphous silicon during annealing. This linearity or periodicity is processed as an image and represented numerically from the image by exploiting the linearity or periodicity. The state of the polysilicon film is checked based on the numerical results.

摘要： A method of recovering valuable materials from lithium batteries wherein a lithium/transition metal composite oxide is used as a positive electrode active material. In this disposal method, a sheeted positive electrode having a positive electrode active material disposed on a positive electrode collector is immersed in an oxalic acid solution. By virtue of this oxalic acid treatment (step 240), any lithium element contained in the positive electrode active material can be leached into the oxalic acid solution. Using oxygen gas produced by a reaction between the positive electrode active material and oxalic acid, attachments, such as the positive electrode active material, can be self-detached from the positive electrode collector. The transition metal element contained in the positive electrode active material is converted by the oxalic acid treatment to insoluble transition metal compounds (oxalate, oxide, etc.). Thus, though simple means such as filtration (step 244), the leached lithium element can be easily separated from the insoluble transition metal element.
