摘要： Disclosed herein is a prismatic battery having an electrode assembly mounted in a prismatic battery case, wherein an electrolyte injection hole formed in a base plate mounted to an open upper end of the battery case is constructed such that an inside upper end of the electrolyte injection hole is formed in a downward taper (incline) structure, and a metal ball is forcibly inserted into the electrolyte injection hole such that the metal ball is plastically deformed to seal the electrolyte injection hole. The prismatic battery according to the present invention provides high coupling force between the metal ball and the electrolyte injection hole due to the plastic deformation and forced insertion of the metal ball and high sealability of the electrolyte injection hole. Also, the formation of a groove at the upper end of the forcibly inserted metal ball and the generation of cracks at the interface between the metal ball and the inside surface of the electrolyte injection hole are effectively prevented. Consequently, the present invention has the effect of accomplishing high electrolyte sealability.
摘要翻译：本文公开了一种棱柱电池，其具有安装在棱柱形电池壳体中的电极组件，其中形成在安装到电池壳体的敞开的上端的基板中的电解质注入孔被构造成使得电解质注入孔的内部上端形成为向下锥形（倾斜）结构，并且金属球被强制地插入到电解质注入孔中，使得金属球塑性变形以密封电解质注入孔。根据本发明的棱柱形电池由于塑性变形和金属球的强制插入以及电解液注入孔的高密封性而在金属球和电解液注入孔之间提供了高耦合力。此外，有效地防止了在强制插入的金属球的上端形成槽并且在金属球和电解液注入孔的内表面之间的界面处产生裂纹。因此，本发明具有实现高电解质密封性的效果。
