−固体状の第1の前躯体と同じ形態を示し、例えば、小片形状であり、好ましくは、実質的に正方形又は長方形の断面を有し、側面(side)は、約数マイクロメートルのディメンションを有し、厚さは、10nmから1μmの間であり、それらは、合成条件に依存する。
−電流コレクタとして動作するニッケル板(nickel disk)の上に積層された、直径16mm、厚さ130μmのリチウム板(lithium disk)によって形成された負極電極と、
−上記の例によって用意された本発明の材料(80重量%)と、カーボンブラック(10重量%)と、結合剤としての六フッ化ポリビニリデン(polyvinylidene hexafluoride)(10重量%)と、を備え、厚さ20マイクロメートルのアルミニウム電流コレクタの上に堆積される、直径14mm、厚さ25μmの板(disk)によって形成された正極電極と、
−炭酸プロピレン(propylene carbonate)と、炭酸ジメチル(dimethyl carbonate)と、が混合された溶液中のLiPF6塩基(salt-base)(1mol/L)の液体電解質を吸収する、セパレータと、
上記のリチウム蓄電池の最初の充電/放電サイクルに対応する、図7中の曲線Cに示されるように、20℃、C/10の条件において、正電極材料中に存在するリチウムのほとんどは、脱離(extract)されることが可能となる。
