Effect of morphology and texture on electrochemical properties of graphite anodes

Three different natural graphite powders (MPG, SPG and HPG) were used to make anode films of lithium-ion batteries by rolling technique. It was found that particle size and particle distribution of graphite, as well as particle orientation in the foil, show great influence on the electrochemical per...

Description
Summary:Three different natural graphite powders (MPG, SPG and HPG) were used to make anode films of lithium-ion batteries by rolling technique. It was found that particle size and particle distribution of graphite, as well as particle orientation in the foil, show great influence on the electrochemical performance of graphite foil anodes. Different X-ray experiments were performed to study the mosaic distributions and coherence lengths of graphite crystallites. This study of the morphology and texture characteristics of anode foils reveals results that pertain to the understanding of electrochemical performance of cells.
