STUDY ON THE CARBONIZED PRODUCT OF FURFURALCOHOL RESIN AS ELECTRODE MATERIALS OF LITHIUM ION BATTERIES(I)— TEST AND ANALYSIS OF THE ELEMENTARY COMPOSITION AND STRUCTURAL PARAMETER OF THE CARBONIZED PRODUCT

Furfuralcohol resin was carbonized to make carbon materials. The elements and structure of resin carbon materials were analyzed. Results showed that during the carbonization of furfuralcohol resin C O bond rupture of pentacyclic ring, took place firstly, bringine C H bond rupture. Then a hexacyclic ring system formed as a result of molecular recombination, based on which further dehydrogenation occurred. In the resin carbon materials treated at 620 ℃ the (100) crystal plane diffraction peek appeared evidently, at the same time the (110) and (006) crystal plane diffraction peeks also appeared. It means that the furfuralcohol resin is a type of facility graphitisable material. The specific surface area of the resin carbon declined with the increase of treatment temperature . As compared with the sample treated at 620 ℃, the specific surfaces area of samples treated at 700 ℃ and 1 000 ℃ descended about 11.2 % and 35.2 % respectively. The treating ambience affected the specific surface area of resin carbon material more remarkably. As compared with the sample treated at 700 ℃ in reducing atmosphere, the specific surfaces area of samples treated at 700 ℃ in inert one descended about 61.5 %.
