摘要： A negative electrode active material for an electric device according to the present invention includes crystalline metal having a structure in which a size in a perpendicular direction to a crystal slip plane is 500 nm or less. More preferably, the size in the perpendicular direction to the crystal slip plane is controlled to become 100 nm or less. As described above, a thickness in an orientation of the slip plane is controlled to become sufficiently small, and accordingly, micronization of the crystalline metal is suppressed even if breakage occurs from the slip plane taken as a starting point. Hence, a deterioration of a cycle lifetime can be prevented by applying the negative electrode active material for an electric device, which is as described above, or a negative electrode using the same, to an electric device, for example, such as a lithium ion secondary battery.
摘要翻译：根据本发明的用于电子器件的负极活性材料包括具有垂直于晶体滑移面的尺寸为500nm以下的结构的结晶金属。更优选地，将与晶体滑移平面垂直的方向上的尺寸控制在100nm以下。如上所述，控制滑动平面的取向的厚度变得足够小，因此即使从作为起点的滑动面发生断裂，结晶金属的微细化也被抑制。因此，通过将如上所述的电气装置用负极活性物质或使用其的负极活性物质，例如锂离子（例如锂离子）二次电池
