摘要: The electrochemical and thermal stability of were studied before after coating. Different to conventional coating material such as or AlPO4, the layer was not detected clearly by TEM analysis, indicating that nanoparticles effectively reacted with surface impurities . coated sample showed similar capacity at a low C rate condition. However, capability significantly improved effect. It is associated decrease impedance because can act major barrier for overall cell performances in high cycling. In DSC profile charged sample, exothermic peaks shifted temperatures heat generation reduced coating, reaction between electrode electrolyte sucessfully suppressed nanoparticle
