Description
本発明における電極の活物質とは、充電反応および放電反応等の電極反応に直接寄与する物質のことであり、電池システムの中心的役割を果たすものである。
前記式(1)で表される繰り返し単位を有する重合体を用いて電極を形成する際に、インピーダンスを低下させる目的で、補助導電材やイオン伝導補助材を混合させることもできる。これらの材料としては、補助導電材としてグラファイト、カーボンブラック、アセチレンブラック等の炭素質微粒子、ポリアニリン、ポリピロール、ポリチオフェン、ポリアセチレン、ポリアセン等の導電性高分子が挙げられ、イオン伝導補助材としては高分子ゲル電解質、高分子固体電解質等が挙げられる。
電極の各構成材料間の結びつきを強めるために、電極材料に結着剤を混合することもできる。このような結着剤としては、ポリテトラフルオロエチレン、ポリフッ化ビニリデン、ビニリデンフルオライド−ヘキサフルオロプロピレン共重合体、ビニリデンフルオライド−テトラフルオロエチレン共重合体、スチレン−ブタジエン共重合ゴム、ポリプロピレン、ポリエチレン、ポリイミド、各種ポリウレタン等の樹脂バインダが挙げられる。
電極反応をより潤滑に行うために、酸化還元反応を助ける触媒を電極材料に混合することもできる。このような触媒としては、ポリアニリン、ポリピロール、ポリチオフェン、ポリアセチレン、ポリアセン等の導電性高分子、ピリジン誘導体、ピロリドン誘導体、ベンズイミダゾール誘導体、ベンゾチアゾール誘導体、アクリジン誘導体等の塩基性化合物、金属イオン錯体等が挙げられる。
負極集電体および正極集電体として、ニッケルやアルミニウム、銅、金、銀、アルミニウム合金、ステンレス、炭素等からなる箔、金属平板、メッシュ状などの形状のものを用いることができる。また、集電体に触媒効果を持たせたり、活物質と集電体とを化学結合させたりしてもよい。一方、セパレータは、上記の正極と負極が短絡しないように接触しない形状や絶縁性を有するものとして、ポリエチレン、ポリプロピレン等からなる多孔質フィルムや不織布などを用いることもできる。
本発明において、電解質は、負極と正極の両極間の荷電担体輸送を行うものであり、一般には20℃で10−5〜10−1S/cmのイオン伝導性を有していることが好ましい。電解質としては、例えば電解質塩を溶剤に溶解した電解液を利用することができる。
本発明において、電池の形状は特に限定されず、従来公知のものを採用することができる。例えば、電極積層体あるいはその巻回体を金属ケース、樹脂ケース、あるいはアルミニウム箔などの金属箔と合成樹脂フィルムからなるラミネートフィルム等によって封止したもの等が挙げられる。またその外観形状としては、円筒型、角型、コイン型、シート型等が挙げられるが、本発明はこれらに限定されるものではない。
電池の製造方法としては特に限定されず、材料に応じて様々な方法を用いることができる。例えば、活物質を含む電極材料に溶剤を加えスラリー状にして電極集電体に塗布し、加熱もしくは常温で溶剤を揮発させ、その後に、セパレータを介して対極を積層し、あるいはさらにこれを巻回して、外装体で包み、電解液を注入して封止する方法がある。スラリー化のための溶剤としては、テトラヒドロフラン、ジエチルエーテルなどのエーテル系溶媒、N−メチルピロリドン等のアミン系溶媒、ベンゼン、トルエン、キシレンなどの芳香族炭化水素系溶媒、ヘキサン、ヘプタンなどの脂肪族炭化水素系溶媒、クロロホルム、ジクロロメタン等のハロゲン系炭化水素系溶媒等が挙げられる。
以下、本発明を実施例により具体的に説明するが、本発明はこれらの実施例に限定されるものではない。
ポリ(2,2,3,3−テトラメチルエチレンニトロキシル)(式(A)で表される化合物)300mg、グラファイト粉末600mg、ポリテトラフルオロエチレン樹脂バインダ100mgを測り採り、メノウ乳鉢を用い10分間混練することにより乾式混合した。なお、ポリ(2,2,3,3−テトラメチルエチレンニトロキシル)の分子量をGPCにより測定した結果、重量平均分子量は8900(ポリスチレン換算)、分散度(重量平均分子量/数平均分子量)は1.82であった。
ポリ(2,2,3,3−テトラメチルエチレンニトロキシル)の代わりにポリ(2,2,3−トリメチル−3−プロピルエチレンニトロキシル)(式(B)で表される重合体)を用いた以外は、実施例1と同様にしてコイン型電池を作製した。このコイン型電池の正極の重さは20mgであった。
ポリ(2,2,3,3−テトラメチルエチレンニトロキシル)の代わりにポリ(2,3−ジメチル−2,3−ジフェニルエチレンニトロキシル)(式(C)で表される重合体)を用いた以外は、実施例1と同様にしてコイン型電池を作製した。このコイン電池の正極の重さは19.1mgであった。
