LiCoO 2薄膜阴极沉积到烧结氧化铝和Si/SiO2衬底上。在800°C下在O2中退火30分钟后，沉积在氧化铝上的膜由具有若干裂纹的大颗粒组成，而沉积在Si衬底上的膜由非常小且均匀的颗粒组成。沉积在Si上的膜表现出改善的电化学性能，如峰值电位发散和倍率性能，超过氧化铝基板电极的那些，这可以归因于颗粒尺寸、表面形貌和集流体的低电阻的差异。© 1999电化学学会。S1099-0062（99）06-030-7。All rights reserved.
An LiCoO2 thin-film cathode was deposited onto sintered alumina and Si/SiO2 substrates. After annealing at 800°C in O2 for 30 min, the film deposited on alumina consisted of large particles with several cracks, whereas the film deposited on the Si substrate was composed of very small and uniform particles. The films deposited on Si showed improved electrochemical properties, such as peak potential divergence and rate capability, over those for the alumina substrate electrode, which can be attributed to differences of the particle size, surface morphology, and the low electrical resistance of the current collector. © 1999 The Electrochemical Society.
