Description
本発明の枠内で発見されたのは、全固体蓄電池の製造、とりわけ全固体リチウムイオン蓄電池の製造を、有利には固体電解質を基礎として、およびこれまでのように電極側の一方からではなく行えるということである。したがって固体電解質は、電気化学セルの製造時に機械的支持の役割を担う。
- 酸化物、例えばLi7-xLa3Zr2AlxO12、ここでx=0~0.5、またはLi7La3Zr2-xTaxO12、ここでx=0~0.5、
- リン酸リチウムアルミニウムチタン、例えばLi1+xMxTi2-x(PO4)3、ここでx=0~7およびM=Al(LATP)、Fe、Y、またはGe、
- ジルコン酸リチウムランタン、この場合、追加的にタンタル、アルミニウム、および鉄のドーピングを用いることができる、
- 硫化リンリチウム、この場合、ゲルマニウムおよびセレンをドーピングすることができ、例えばLi7P3S11、Li10P3S12、Li10MxP3-xS12、ここでM=Ge、Seおよびx=0~1、ここでM=AyBz、これに関しA=Si、GeおよびB=Sn、Siならびにここでy=0~0.5およびz=1-y。
LiNiCoAlO2、LiNiCoMnO2(NMC)、LiMn2-xMxO4、ここでM=Ni、Fe、Co、またはRu、およびここでx=0~0.5、ならびにLiCoO2(LCO)である。
V2O5、LiVO3、Li3VO4、およびLi4Ti5O12(LTP)が適している。
前か焼したリン酸リチウムアルミニウムチタン(LATP)粉末を、ボールミル内で粉砕した後(粉砕後の平均粒径、d50<1μm)、一軸ピストンプレス機内で直径11mmのペレットへと加圧する(40kN)。
