示例性地，如图4所示，电池盖板还包括防爆片400，在盖板本体100上开设有防爆孔102，防爆片400设置于防爆孔102内。在防爆片400上粘贴有防爆片贴膜401。盖板本体100上设置防爆片400，防爆片400采用环形压痕或多个弧形压痕，当电池内部发生异常，电池内部气体的压力超过防爆片400的防爆应力预设值时，会先从防爆片400的压痕处裂开，从而释放出电池内部的气体，防止动力电池爆炸，降低动力电池的安全隐患。
在本实施例的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本实用新型中的具体含义。
在本实施例中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本实施例的描述中，术语“上”、“下”、“右”等方位或位置关系为基于 附图所示的方位或位置关系，仅是为了便于描述和简化操作，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。此外，术语“第一”、“第二”仅仅用于在描述上加以区分，并没有特殊的含义。
