Description
本出願は、2016年10月17日出願の日本出願第2016−203186号に基づく優先権を主張し、前記日本出願に記載された全ての記載内容を援用するものである。
特許文献1及び特許文献2に記載されているように、非水電解質電池用リード線において、絶縁層の一部に架橋層を用いることで熱融着時に封入容器の金属層とリード導体との短絡を防ぐことができる。架橋層としては通常ポリプロピレンの架橋体が使用されている。
本発明の実施形態によれば、成形設備や製品に悪影響を及ぼすことがなく製造できるとともに、封入容器の金属層とリード導体との短絡を発生させることなくリード導体と封入容器との接着性を維持できる非水電解質電池用リード線及びそれを含む非水電解質電池を提供できる。
図1は非水電解質電池の一実施形態を模式的に表す正面図であり、図2は図1のA−A’部における部分断面図である。この非水電解質電池1は、略長方形の封入容器2と、封入容器2の内部から外部に延びるリード導体3を有している。リード導体3と封入容器2とは、第一の絶縁層4bと第二の絶縁層4aを介してシール部9で接続されている。
[絶縁層形成用樹脂組成物の作製]
絶縁層形成用樹脂組成物の調整に用いた化合物を以下に示す。
(樹脂成分)
ランダムポリプロピレン(ランダムPP):ノバテック(登録商標)FX4G(融点130℃、MFR5g/10min)
酸変性ランダムポリプロピレン混合物(酸変性ランダムPP混合物):アドマー(登録商標)QF551(融点135℃、MFR6g/10min)
オレフィン結晶・エチレンブテン・オレフィン結晶ブロックポリマー(CEBC):ダイナロン(登録商標)6200P
エチレンブテン共重合体1:タフマー(登録商標)DF640(融点55℃、MFR6g/10min)
エチレンブテン共重合体2:タフマー(登録商標)DF610(融点55℃、MFR3g/10min)
エチレンプロピレン共重合体:タフマー(登録商標)P280(融点55℃、MFR5g/10min)
エチレンオクテン共重合体:エンゲージ(登録商標)8150(融点55℃、MFR1g/10min)
(架橋助剤)
架橋助剤1:トリアリルイソシアヌレート
架橋助剤2:トリメチロールプロパントリメタクリレート
(酸化防止剤)
酸化防止剤1:イルガノックス(登録商標)1010
酸化防止剤2:イルガノックス(登録商標)1076
上記材料を用い、表1及び表2に示す配合(質量部)で各材料を混合して絶縁層形成用樹脂組成物を得た。得られた樹脂組成物をTダイ法を用いてシート状に成形した。ニップロール方式を用いて、Tダイのダイス厚みを0.05mm、ダイス−冷却ロール間のエアギャップを50mmに設定し、厚み0.05mmの絶縁層を形成した。成膜速度を徐々に上げ、良好にシートを作製可能な成膜速度を測定した。成膜速度10m/min以上を合格値とした。なお成膜時の室温は10℃とし、成膜時の架橋助剤の蒸気発生量を目視で観察した。
得られた絶縁層に120kGyのγ線を照射して架橋させた。
上記架橋した絶縁層シートを定型サイズに切り取り、室温で一定期間保管した。このシートの表面にブリードアウトした架橋助剤の量をATR−IRで定量した。具体的には、架橋助剤に特徴的なピーク(1700cm−1)において、フィルムをそのまま測定した時のピーク高さ(A%)とフィルム表面をエタノールで拭き取ってから測定した時のピーク高さ(B%)を測定し、A−Bが4%となるまでの期間を求めた。4週間以上を合格とした。なお、表中の「なし」は架橋助剤が含まれていないために、特徴的なピークが検出されなかったことを示す。
上記架橋した絶縁層シートの加熱変形残率を評価した。具体的には、シートサンプルをTMA(Thermal Mechanical Analysis)装置に入れ、プローブに0.1MPaの荷重をかけた状態で昇温し、室温での厚みと200℃での厚みを測定した。室温での厚みに対する200℃での厚みの比を加熱変形残率(%)とした。40%以上のものを合格とした。以上の結果を表1及び表2に示す。
