Stage-n Fe&GICs (n = 2,3) prepared in the standard two-zone method were oxidized galvanostatically in H,SO,. The electrode potential vs. electric quantity curves observed during the treatment and the X-ray powder patterns of the products showed clearly the intercalation of H,SO, into FeCI,-GICs and

The results of this paper have shown that the ternary stage-2 CrO,PH,SO,-graphite intercalation compound is electrochemically formed on the subsequent intercalation of H,SO, into the host stage-5 CrO,-GIG/graphite matrix. In contrast to the binary H,SO,-GIC easily deintercalated upon cathodic reduct
## We present experimental results on stage stability and stage transition in H,SO,-GDICs by X-ray measurements, and electronic energy state by UV/VIS spectrophotometer measurements. From the results of X-ray measurements, it is shown that the changes of stage and d, value are irregular and occur
