・ 前記熱処理が2段階で行われる:第一段階は1〜12時間かけて90℃〜150℃の温度で、第二段階は10分〜1時間かけて420℃〜500℃の温度で、窒素もしくはアルゴン雰囲気下または真空下で行われること。
・ リチウム前駆物質は、Li2CO3、LiOH・H2O、LiCl、LiNO3または、例えばリチウムアセチルアセトナート、酢酸リチウム、ステアリン酸リチウム、蟻酸リチウム、しゅう酸リチウム、クエン酸リチウム、乳酸リチウム、酒石酸リチウムまたはピルビン酸リチウムから選択されるカルボン酸のリチウム塩から選ぶことができる。
・ α−V2O5および炭素の水懸濁液を製造し、過酸化水溶液をその中に添加する。過酸化水溶液の添加前または添加後、すなわちゲルが形成される間に、リチウム前駆物質を、α−V2O5および炭素の水懸濁液に添加することができる。そして、この混合物を5分間、強く攪拌する。
・ 反応媒体中のLi前駆物質およびα−V2O5のそれぞれの量は、好ましくは0.1/z mol.l-1<[Li]<11/z mol.l-1;0.1mol.l-1<[V2O5]<1mol.l-1である。zは前駆物質の式単位ごとのリチウム原子数である。
・ 本発明のプロセスで得られた炭素含有または炭素非含有化合物
・ 機械的強度を与えるバインダー
・ 任意の電子伝導性を与える化合物
・ 任意のイオン伝導性を与える化合物
24.0810g(0.88M)のα−V2O5、4.7916g(0.44M)のLi2CO3および3.5gの炭素を150mlの水に添加した。ビーズミルで2時間攪拌後、炭素ならびにLiおよびVの前駆物質から形成される組成物が形成された。次に、前記組成物を、空気中で2時間、90℃で乾燥し、そしてアルゴン雰囲気下で15分間、420℃の処理にかけた。得られた生成物を、今後GliV2O5−420と呼び、それは残留炭素を8%含む。
15分間の処理の420℃を470℃に変えて、例1の製造プロセスを用いた。得られた化合物を、GliV2O5−470aと呼び、それは残留炭素を8%含む。
24.0810g(0.29M)のα−V2O5、4.7916g(0.146M)のLi2CO3および1.49gの炭素を50mlの水に添加した。ビーズミルで2時間攪拌後、炭素ならびにLiおよびVの前駆物質から形成される組成物が形成された。次に、前記組成物を、空気中で2時間、90℃で乾燥し、そしてアルゴン雰囲気下で15分間、470℃の処理にかけた。得られた生成物を、今後GliV2O5−470bと呼び、それは残留炭素を1%含む。
470℃の処理を、30分間、350℃に変えて、例3の製造プロセスを用いた。得られた化合物をGliV2O5−LIV−350と呼ぶ。
1gのV2O5、0.2306gのLiOH・H2Oおよび0.1453gの炭素を15mlの30%過酸化水素水溶液に添加した。炭素ならびにLiおよびVの前駆物質から形成される組成物が数分間で形成された。
水添加なしでミル分散を行い、470℃での処理を15分間に代えて45分間行う以外は、例2の製造プロセスを用いた。得られた化合物を、GliV2O5−BSEC−470と呼び、それは不純物としてのβ−LixV2O5を含む。
X線回折解析
化合物GliV2O5−420、GliV2O5−470aおよびGliV2O5−BSEC−470のX線回折ダイアグラム、ならびに、ビーズミルで2時間攪拌後、炭素およびLiとVの前駆物質から形成され、熱処理の第二段階は行わずに空気中で2時間、90℃で乾燥した組成物のX線回折ダイアグラムを図1に示す。これらのダイアグラムは、炭素含有γ−LiV2O5が15分間の420℃のアニーリングで得られることを示す。さらに、470℃の乾燥混合物は、45分後でさえ、β−LixV2O5タイプの不純物(*)の出現をもたらすので、ミル分散の間の水の使用が、炭素およびLiとVの前駆物質から形成された組成物の反応性を改良できることを示す。その上、比較例6によって作製された炭素およびLiとVの前駆物質から形成された組成物の回折図は、それが炭素(11%)に加えて、式Li1+aV3O8・1H2Oの層状の水和物を含むことを示す。
性能の測定
例3によって製造した化合物GliV2O5−470bおよび例4によって製造した化合物GliV2O5−LIV−350の電気化学性能を、Li/液体電解質(EC+DMC+LiPF6)/GliV2O5−470b型Swagelok(登録商標)式検査用電池を使用して、周囲温度で検査した。正電極として、本発明の化合物にカーボンブラックを5重量%加えた。
