Description
現在、自動車の電化は著しく促進されていて、この場合、特に、リチウムイオンバッテリーが研究の焦点となっている。消費者にとって魅力的であるためには、電気自動車に使用するためのバッテリーは、長い寿命(>10年)を保証しなければならない。これは、セル電圧及び放電時に放出されるエネルギーが10年後でもなお、出発値の約≧90%であるのが好ましいことを意味する。特に、いわゆる高エネルギー材料、例えば高エネルギーNCM(LiMO2:Li2MnO3、式中M=ニッケル(Ni)、コバルト(Co)、マンガン(Mn))の場合に、この要求はいまだに満たされていない。このHE−NCMは、今まで高い初期電圧を提供しているが、寿命の経過において電圧状態の明らかな損失(Voltage Fade)が容量の低下(Capacity Fade)を伴って現れる。従って、この基本的に極めて魅力的な材料のHE−NCMは今までは商業的な利用にとって適していない。
本発明の主題は、電気化学的エネルギー貯蔵装置用の、特にリチウムセル用の、遷移金属酸化物を基礎とする第1のリチウム化可能な活物質を含む粒子を備えた電極、特にカソードにおいて、
− この粒子又は
− この粒子を含む基体に、
少なくとも部分的に、リチウムイオン伝導性でかつ少なくとも1種のレドックス活性元素を含む機能層が設けられている、電極、特にカソードである。
− Ni、Co、Mn及びNb塩+Na2CO3+NH4OH(キレート生成剤)
− 50℃ 水浴 12時間
− LiOHと混合
− 焼成及び液体N2中で急冷。
− 遷移金属酸化物を基礎とする、少なくとも1種の第1のリチウム化可能な活物質を含む粒子を準備する工程;
− この粒子を、リチウムイオン伝導性でありかつレドックス活性元素を含む機能層で被覆する工程;
− 導電性添加物及び結合剤を添加する工程;
− 機能層を備えた粒子、導電性添加物及び結合剤からなる群からなる成分を乾式プレスするか、又は機能層を備えた粒子、導電性添加物及び結合剤からなる群からなる成分を溶媒、特にN−メチル−2−ピロリドン中に分散させる工程;
− こうして得られた分散物を金属支持体、特にアルミ箔に塗工する、特にブレード塗布する工程;及び
− 場合により分散物を乾燥する工程(単一粒子被覆、single particle coating)。
− 遷移金属酸化物を基礎とする、少なくとも1種の第1のリチウム化可能な活物質を含む粒子を準備する工程;
− 導電性添加物及び結合剤を添加する工程;
− 粒子、導電性添加物及び結合剤からなる群からなる成分を乾式プレスするか、又は粒子、導電性添加物及び結合剤からなる群からなる成分を溶媒、特にN−メチル−2−ピロリドン中に分散させる工程;
− 粒子を含む基体を形成するために、こうして得られた分散物を金属支持体、特にアルミ箔に塗工する、特にブレード塗布する工程;
− 場合により、この分散物を乾燥する工程;
− この基体を、リチウムイオン伝導性でありかつレドックス活性元素を含む機能層で被覆する工程(積層体被覆)。
本発明を次に添付の図面を用いて例示的に詳細に説明する。
