Disclosed herein is a battery module constructed in a structure in which a plurality of plate-shaped battery cells are stacked one on another. The battery module has attachment members interposed between the battery cells to prevent the battery cells from sliding due to external impacts and also to absorb the external impacts. The battery cells are securely attached to each other by the coupling between the attachment members, such as female- and male-type Velcro tapes. Consequently, the sliding of the battery cells due to external impacts is effectively prevented. Also, the female- and male-type Velcro tapes are elastically deformed, when the external impacts are applied to the battery cells, to absorb the external impacts. In addition, it is possible for a coolant, such as air, to pass through the coupled Velcro tapes by virtue of the structural characteristics of the female- and male-type Velcro tapes. Consequently, the cooling efficiency of the battery module is improved. Furthermore, the long-term use of the female- and male-type Velcro tapes is secured without the reduction of the attachment strength thereof, and therefore, the stacked structure of the battery module is stably maintained.

A window cavity is made on back face of basal body of diamond coat through chemical corrosion, microprocessing or other method in order to expose inner surface, which is contacted to basal body before window cavity is made. Pressure is applied to the coat by using pressure oil through window cavity. The coat is deformed under action of even load. Based on Pascal law and theory of plate and shell, theoretical model of inner expand and bubbling method for detecting adhesive strength of coat is deduced, and calculating program is converted from the said model. Thus, testing the deformation of diamond coat and relevant pressure can calculate out adhesive strength of diamond coat. The method calculates strength with accuracy without limit of shape of basal body and magnitude of intensity.
