Description
おいて、形状がコイン形であることを特徴とする。
加えて、電池の組立後にリフローハンダ付け実装工程のような高温に加熱される工程を経ると、このような高温に加熱される工程が存在しない通常の場合と比すると、かえって電池の2サイクル目以降の放電特性が良好となる。
従来の非水系電解液二次電池では高温に加熱されるようなことは電池劣化の原因となるために避けるべきであるとされているのに対し、本発明の非水系電解液電池ではかえって2サイクル目以降の放電特性が良好となる。
正極活物質としてリチウムモリブデン酸化物(Li2MoO3)の粉末90質量%に対し導電剤としてカーボン10質量%をよく混合し、この混合物に結着剤5質量%を添加してよく混練し、粉砕・整粒して正極合剤を作成した。そして、この正極合剤を5トン/cm2の圧力により加圧成形して、直径2mm、厚み1.0mmの円筒状の正極を作成し、250℃で熱処理することにより正極に含まれる水分を除去して使用した。
負極にアルミニウム−ステンレススチールからなるクラッド材を使用し、このクラッド材のアルミニウム金属側の上にガラス繊維不織布からなるセパレータを設置し、そのセパレータに対して電解液を4mg注入した。この上に、上記のようにして作製した正極を置き、ガスケットを介してステンレス鋼製の正極缶を被せ、かしめることにより厚み1.4mm、外形4mmの電池とした。このときの電解液は、プロピレンカーボネートとジエチレングリコールジメチルエーテルとを体積比が50:50で、LiN(CF3SO2)2を1Mとなるように添加したものを用いた。このようにして作製した電池を以下「A1」と称する。
上記の方法で作成したA1、A2、A3の電池に対して、240℃のリフローハンダ付け工程を行わなかった「リフローなし」電池と、240℃のリフローハンダ付け工程を2回行った「240℃リフロー」電池について以下の充放電条件でサイクル試験を行った。
充電条件:電池電圧3Vとなるまで20μAの定電流で充電。
その後、3Vの定電圧で30時間充電。
放電条件:20μAの定電流で電池電圧が2Vとなるまで放電。
