ELEKTRODE AUS KOHLENSTOFFASERN FÜR SEKUNDÄRBATTERIE

摘要

The carbon fibers present a mean lattice surface spacing (d002) not less than 0.36 nm, preferably 0.38 nm, at a crystallite size such that the mean height (Lc) lies in the range 0.7 nm to 0.3 nm and the mean width (La) lies in the range 2 nm to 6 nm, and it presents total porosity lying in the range 10% to 30%. The electrode is preferably a rayon-precursor carbon cloth and it constitutes the anode (10) of a secondary cell having a cathode (20) which includes lithium enabling lithium ions to be inserted and de-inserted, and an electrolyte (30).
