Abstract
Description
炭酸リチウム、水酸化アルミニウム、酸化チタンおよびリン酸二水素アンモニウムを含んでなる出発物質を、Li1.4Al0.4Ti1.6(PO4)3を製造するために適切な比率で混合した。次いで、混合した材料を白金るつぼ中、700℃で焼成した。次いで、混合相生成物を粉砕し、粒径が約10μm未満となるまでジェットミル加工し、次いで、700℃で第2の焼成を行った。このプロセスによって、NASICON型構造を有するほぼ純粋なLATPが製造されることがわかった。生成物を再び粉砕し、破砕して粗い粉末にし、エタノール中で湿式アトリションミル加工し、約0.3μmの平均粒径を有する生成物を製造した。スリップを調製するために、高品質のキャスティングを製造するスリップを製造するために適切なレベルで、ポリビニルブチラール結合剤、フタル酸ジブチル可塑剤およびPS−236分散剤を添加した。次に、無機固体含有量の約2重量%P2O5の量のリン酸を添加し、さらに混合した。
レーザー切断
次いで、大きい電解質シートを支持体上に配置し、そしてアブレーティブレーザー、3倍波Nd:YVO4レーザーによって所望の仕上げ寸法に切断した。このレーザーは、355nmの波長、50kHzの繰り返し速度、230mm/秒の切断速度および190J/cm2のフルエンスを有した。
Claims (1)
- 少なくとも1つのアブレーティブエッジを有してなる、セラミックリチウムイオン電解質膜であって、約5μm未満の平均粒径を有する粉末を含み、約90%より高い相対密度を有し、約200μm以下の厚さを有し、前記少なくとも1つのアブレーティブエッジが外部エッジである、セラミックリチウムイオン電解質膜。
