有机溶剂分离法处理废旧锂离子电池 总被引:10,自引:0,他引:10
针对现有废旧锂电池回收钴金属工艺中铝钴分离的问题,采用特定的有机溶剂分离法,使锂电池正极材料中的钴酸锂从铝箔上溶解下来,直接分离钴酸锂和铝箔,铝箔经清洗后直接回收,所用的有机溶剂通过蒸馏方式脱除粘结剂,实现循环使用。该工艺简化废旧锂电池正极材料的回收处理工艺流程,有效地回收钴与铝。 相似文献

Stainless steel foil has properties which are, in many respects, unmatched by alternative thin films. The high strength to
weight ratio and resistance to corrosion and oxidation at elevated temperatures are generally advantageous. The aerospace
and automotive industries have used Type 430 and 304 foil in turbine engine applications. Foil around 2 mils (5.1 × 10-3 cm) thick has been appropriate for the recuperator or heat exchanger and this product has also been used in honeycomb and
truss-core structures. Further, such foil has been employed as a wrap to protect tool steel parts from contamination during
heat treating. A large part of the high cost of producing stainless steel foil by rolling is due to the complicated and expensive
rolling mill and annealing equipment involved. A method will be described which produces (solid) stainless steel foil from
chromized (coated) steel which can be cheaper than the conventional processing stainless steel, such as Type 430, from ingot
to foil. Also, the material is more ductile and less work hardenable during processing to foil and consequently intermediate
annealing treatments are eliminated and scrap losses minimized.

配制了6种不同含镉量(质量分数小于0.02%)的电解电容器用铝箔合金,研究了微量镉对铝箔性能的影响,结果发现,微量镉使铝箔硬度增加,晶粒组织细化,经低压形成 液处理的铝箔随镉含量的增加其电容容量也增加,经高压形成液处理的铝箔添加适量的镉可使电容量达到最佳值. 相似文献
