摘要

Cobalt oxides are a promising anode material for lightweight rechargeable lithium-ion batteries. Thus, the low temperature deposition of cobalt oxide is a key-technology for the production of flexible energy storage systems enabling novel application opportunities such as wearables. To satisfy the emerging process requirements the dicobaltatetrahedrane precursor [Co-2(CO)(6)(eta(2)- H-C equivalent to C-(C5H11)-C-n)] was investigated for the low- temperature chemical vapor deposition of cobalt oxides. Oxygen, water vapor and a combination of both were examined as possible co- reactants. In particular, wet oxygen proves to be an appropriate oxidizing agent providing dense and high purity cobalt oxide films within the examined temperature range from 130 degrees C to 250 degrees C. Film growth occurred at temperatures as low as 100 degrees C making this process suitable for the coating of temperature- sensitive and flexible substrates.
