Effect of ZnCl2Doping on the Structure and Properties of Carbonized Phenolic Resin Material

Abstract

Abstract: The influence of ZnCl₂doping on the structure and properties of carbonized phenolic resin material was investigated in detail. The structure and electrochemical properties of the carbonaceous material were measured by means of XRD, SEM, BETand Raman analyses, respectively. The results show that after doping ZnCl₂, the crystallinic size and distance between layers become larger, the partical size also tends to be uniform, the apertures and specific surface area of the product tend to be uniform, the apertures and specific and specific surface area of the product are obviousely increased. Moreover, the product size and internal aperture are alLIn nano-level range. By using this carbonaceous product as the electrode material, the reversible discharge capacity of the battery can reach 745mA·h/g.
