Description
本発明の主たる目的は、電子伝導性要素と活物質からなる圧縮された3D電極の前述の優位性を包含するリチウム蓄電池を提供することであり、その3D電極は一方で蓄電池セルの大きな容量を維持しながら放電充電時間が短縮されるという優位性を有する。本発明の他の目的は、電極の圧縮または圧延による効率的な生産を可能にする電極の構造を提供することである。
(技術的解決方法)
本発明の目的は以下のリチウム蓄電池により達成され、またそれにより前述の欠点は解消される:容器をもつリチウム蓄電池であって、少なくとも1つのセルを有し、そのセルは、セパレータによって分離される2つの電極と、集電器と、そして有機溶媒中のリチウム塩の溶液から構成される液体電解質と、を有するリチウム蓄電池において、有機結合剤の無いそれぞれの電極が金属製の網、エキスパンドメタルまたは多孔金属箔の形状での多孔性の細長い金属板から形成される集電器の両側の上に押圧される、ことを特徴とするリチウム蓄電池。
既存技術と異なり、個々の電極またはセルは結合剤により箔の上に取り付けられない。電極は直接、そして有機結合剤無しに、集電器の多孔性の細長い金属板の開口の中にフレームのシステムを用いずに押圧される。
セルは相互にボルトにより接続される2つの端末カバーの間で締め付けられる。
このような材料は好適には、リチウムのインターカーレートプロセスを数秒に短縮する可能性のあるナノ寸法の粒子として存在する。
(有利な効果)
本発明に基づくセパレータの優位点は、その総合的熱安定性と有機結合剤のない電極材料が大幅に低い電気抵抗を有し、そして蓄電池の充放電プロセスにおいて放熱量が有意に少ないという事実に基づく安全性である。有機結合剤が無いことは電極の内部形態と共に、リチウムイオンの電極内での高い移動性を提供する。ここに記載された電極構成と材料組成は、従来のセパレータが使用された場合でも充電器の短縮された充放電時間と高い容積容量の獲得を可能にする。
(実施例1)
図1に概略的断面図として示された蓄電池は、容器10を有し、その中に個々の蓄電池セルが端部カバー1a,1bの間に互いに積み重なって配置される。蓄電池セルは一緒にボルト11で締め付けられる。各セルは1つの正電極2a、1つの負電極2bおよびそれら電極間に位置するセパレータ4から構成される。各正電極2aは集電器3aの中に押圧され、そして各負電極2bは集電器3bの中に押圧される。有機結合剤のない各電極の材料は集電器にフレームなしで、しかしいくらかのオーバーハングを有して押圧され、それにより電極は集電器表面の上および下に伸長し、ここで対向する外部電極面の間の最小距離は集電器3a、3bの厚みの少なくとも3倍に等しい。
リチウム蓄電池はセパレータ4で互いに分離される13個の負電極2bと14個の正電極2aからなる。各電極は2x25mmの広さと0.3−0.35mmの厚みを持つ。正電極は重量比80%の約200nmのLFP粒子からなる典型的に寸法2μm以下の小集団の形態を有するLiFePO4(Life Power(登録商標)−P2(LFP))および重量比10%の電子伝導性カーボンおよび重量比10%の圧縮時に結合特性を持つ導電性圧縮性カーボンから構成される。Ketjen Black EC−300Jの商品名で市販されるこのタイプのカーボンは、比表面積800m2/g、比空隙容積310−345ml/100g、殆ど150nm超の団粒寸法、および密度125−145kg/m3を有する。あるいは商品名EC−600JD,EC−330JMAで販売されるカーボンを使用してもよい。カーボンは厚さ0.04mm、最大孔寸法「a」が1.3mmのアルミエキスパンドメタル集電器の上に約25kN/cm2の圧力で圧迫される。代替として、商品名EC−600JD,EC−330JMAが使用された。
リチウム蓄電池がセパレータ4で分離された12個の負電極2bと13個の正電極2aで構成される。セパレータはセラミックパウダーAl2O3と80μmの厚みのグラスファイバーとの混合物から調製された。正電極の活物質はLiCo1/3Mn1/3Ni1/3O2(NMC)であり、負電極の活物質はナノ粒子形態のLi4Ti5O12(LTS)であった。各電極の広さは2x25mmであり、その厚さは0.3−0.35mmであった。蓄電池モジュールの容積は3.25cm3であり、規定容量は162Wh/リットルであった。
本発明の蓄電池は100℃以上の高温で動作可能なリチウム蓄電池の生産に使用可能である。この蓄電池は今日の高電圧システムを伴う鉛−酸蓄電池の代替、即ち自動車、手持ち電動工具、そして携帯型電気および電子製品および装置用に適している。
