Description
上蓋21を用い、容量が6Ahの電池30を作製した。ダイアフラム2には、厚さ0.6mmのA3003−H14を用い、プレス加工によって皿状の形状とした。スプリッタ18は、厚さ1mmのA3003−H14で作った。また、スプリッタ18の中央にプレス加工により厚さ0.5mmの薄肉部LWを形成した。このとき、薄肉部LWの背面側の外径D2を4mmとし、薄肉部LWの肉は図1のA部に逃がし、ダイアフラム2側に隆起した外径D1を8mmとした。上方への隆起した高さT1をおよそ0.25mmとした。
図5に示した従来例の上蓋20を用いて比較例1の電池を作製した。接続板6に厚さ0.5mmのA3003−H14を用い、接続板6とスプリッタ4とをYAGレーザにより接合した。なお、上蓋20以外は、実施例と同一の構成とした。
上蓋に、図4に示したスプリッタ19を用いて比較例2の電池を作製した。ダイアフラム2側に隆起した外径D1を3.8mm、高さT1をおよそ0.25mm、薄肉部LWの背面側の外径D2を4mm、下方への盛り上がりの高さT2はおよそ0.3mmであった。なお、上蓋以外は、実施例と同一の構成とした。
