Flexible ceramic current collecting layer film green body
The invention discloses a flexible ceramic current collecting layer film green body. Slurry is subjected to tape casting and drying to obtain the product. The slurry comprises 48-65 parts by weight ofraw material powder, 7-21 parts by weight of a toughening agent, 0.1-5 parts by weight of a sintering aid, 1-10 parts by weight of a dispersing agent, 3-8 parts by weight of a binder, 10-20 parts byweight of a plasticizer, 0.5-2.5 parts by weight of a defoaming agent and 50-75 parts by weight of water. wherein the raw material powder is metal oxide and/or metal salt of corresponding metal elements in metal oxide forming the ceramic current collecting layer, and the dosage ratio of the metal elements in the raw material powder is the same as that of the corresponding metal elements in the ceramic current collecting layer; or the raw material powder is powder obtained by crushing a corresponding perovskite phase or spinel phase formed by metal oxide in the ceramic current collecting layer.The film green body has the characteristics of being good in flexibility and easy to cut and is suitable for being installed in a solid oxide fuel cell/electrolytic cell (SOFC/SOEC) to be used as a current collecting layer.
本发明公开了一种柔性陶瓷集流层薄膜生坯，由浆料经流延并干燥而得，所述浆料包括48‑65重量份的原料粉体、7‑21重量份的增韧剂、0.1‑5重量份的助烧剂、1‑10重量份的分散剂、3‑8重量份的粘结剂、10‑20重量份的增塑剂、0.5‑2.5重量份的脱泡剂、和50‑75重量份的水；其中，所述原料粉体为形成陶瓷集流层的金属氧化物中相应金属元素的金属氧化物和/或金属盐，并且所述原料粉体中各金属元素的用量比与陶瓷集流层中相应金属元素的用量比相同；或者所述原料粉体为陶瓷集流层中金属氧化物所形成的相应钙钛矿相或尖晶石相粉碎后的粉体；该薄膜生坯具有柔韧性好、易于剪裁的特点，适宜安装在固体氧化物燃料电池/电解池(SOFC/SOEC)中用作集流层。
