Description
添加剤:新日本理化(株)製N,N’−ジシクロヘキシル−2,6−ナフタレンジカフボサミドNU−110・・・0.05質量部
酸化防止剤:チバ・スペシャルティ・ケミカルズ(株)製、IRGANOX1010・・・0.15質量部
熱安定剤:チバ・スペシャルティ・ケミカルズ(株)製、IRGAFOS168を0.10質量部
これらの混合物を二軸押出機にて供給して300℃で溶融・混練した後、ガット状に押出し、20℃の水槽にて冷却して、チップカッターで3mm長にカットした後、100℃で2時間乾燥する。
(電池部材の作製)
正極シートは、正極活物質としてリン酸鉄リチウム(LiFePO4)100質量部、正極導電助剤としてアセチレンブラック5質量部、正極結着剤として芳香族ポリアミド樹脂5質量部を、プラネタリーミキサーを用いてN−メチル−2−ピロリドン中に分散させた正極スラリーを、アルミ箔上に塗布、乾燥、圧延して作製した。
上記のように作製した正極シートを5cm×4cmに切り出した。このうち、一辺4cm×1cmはタブを接続するための未塗布部であって、正極塗布部は4cm×4cmである。幅5mm、長さ3cm、厚み0.1mmのアルミ製の正極タブを正極未塗布部に長さ1cmで超音波溶接した。
開回路電圧は(株)カスタム社製のデジタルテスターCDM−17Dを用い、正負極間の電池電圧を測定した。電池を25℃±5℃雰囲気下以外の雰囲気下に設置した場合は、25℃±5℃雰囲気下で2時間以上12時間未満放置し、電池温度が一定となった後に開回路電圧を測定した。
寿命特性を下記手順にて試験を行い、寿命容量維持率にて評価した。
充電、放電を1サイクルとし、下記条件を100回繰返し行った。
(100サイクル目の放電容量)/(1サイクル目の放電容量)×100を放電容量維持率とした。放電容量維持率が60%未満を×、60%以上80%未満を○、80%以上の場合を◎とした。
保存特性を下記手順にて試験を行い、保存容量維持率にて評価した。
充電、放電の順に下記条件にて行った。
下記条件にて充電のみを行った。
2サイクル目にて4.2Vまで充電した電池を60℃雰囲気下に28日保存した。
60℃雰囲気下から25℃±5℃雰囲気下へと電池を移し、2時間以上12時間未満放置し、電池温度が一定となった後に下記条件にて放電のみを行った。
(3サイクル目の放電容量)/(1サイクル目の放電容量)=容量維持率とした。
耐熱特性を下記手順にて評価した。
