Abstract
Description
まず、電池セル24を加熱する加熱処理を行う。加熱処理では、電池セル24の電池性能に影響を与えない温度(例えば60℃以下)で加熱する。加熱処理によって、電池セル24の表面から水分が除去され、シリコン含有粒子が付着しやすくなる。
次に、電池セル24にシリコン含有粒子を付着させるシリコン付着処理を行う。シリコン付着処理では、浸漬、ポッティング、スプレー等によって、電池セル24の表面にシリコン含有粒子を付着させることができる。本実施形態では、シリコン含有粒子を液体に分散させたシリコン分散液体に電池セル24を浸漬する浸漬処理を行う。
次に、電池セル24の表面に付着したシリコン分散液体からオイルを除去する液体除去処理を行う。本実施形態では、電池セル24を加熱することで、オイルを気化させてシリコン分散液体からオイルを除去している。
本発明は上述の実施形態に限定されることなく、本発明の趣旨を逸脱しない範囲内で、以下のように種々変形可能である。また、上記各実施形態に開示された手段は、実施可能な範囲で適宜組み合わせてもよい。
24 電池セル
24a 電極端子(活電部、金属電極)
24b 電池ケース(導電部、金属ケース)
25 被覆層
Claims (3)
