METHOD FOR PRODUCING THERMAL INSULATION SHEET
According to the present invention, a fiber sheet that has a first surface and a second surface, which are on the reverse side of each other, while having spaces inside, is prepared. The fiber sheet is impregnated with a silica sol solution, which contains liquid glass and ethylene carbonate, so as to fill the spaces with the silica sol solution. The silica sol solution is gelled, while causing the first surface and the second surface of the fiber sheet to have a temperature difference of 50 DEG C or more, thereby forming a silica gel. The silica gel is hydrophobized. Consequently, a thermal insulation sheet is obtained. The thus-obtained thermal insulation sheet is able to have different compression rates at the first surface and at the second surface with respect to a predetermined pressure. In cases where this thermal insulation sheet is arranged between two battery cells, expansion of one battery cell is able to be prevented from affecting the other battery cell.
准备在内部具有空间且具有彼此相反侧的第1面和第2面的纤维片。使包含水玻璃和碳酸亚乙酯的硅溶胶溶液浸渗于纤维片的空间中。在纤维片的第1面和第2面带有50℃以上的温度差的状态下，使硅溶胶溶液凝胶化而形成硅胶。使硅胶疏水化。由此得到绝热片。如上那样得到的绝热片能够使相对于规定的压力的压缩率在第1面和第2面不同。在将该绝热片配置于2个电池单元间的情况下，即使一个电池单元膨胀，也能够防止对另一个电池单元造成影响。
