查了一篇锂电文献（英文） ，和大家分享 标题：Carbon nanocoatings on active materialsfor Li-ionbatteries 摘要：Carbon coatings were prepared on various submicrometre-sized particles that can be used as active materials in lithium rechargeable batteries. As a precursor citrate anion was used which, after carbonization at 500–600?C, transforms into a uniform, several-nanometre-thick film that is tightly adhered to the surface of substrate particles. The coatings on Li4Ti5O12 and TiO2 increased significantly the average electron conductivity of cathode composite material,which resulted in a more than 100% increase of reversible capacity at a C/3 rate. Additionally, the coating on TiO2 prevented the gradual deterioration of reversible capacity of this material observed in absence of coating. In cases where due to temperature orat mosphere sensitivity of the substrate, carbon nanocoatings cannot beprepared, we propose the use of conductive polymers. As uccessful wiring using as ulphonated polyaniline is demonstrated on the example of MoS2 nanotubes. [ Last edited by lover668 on 2009-8-27 at 22:04 ] |
