摘要 |
Compacted carbon that is useful in the electrode of an alkali metal/carbon electrochemical cell of improved capacity is selected from the group consisting of: (a) coke having the following properties (i) an x-ray density of at least 2.00 g per cubic centimetre (ii) a closed porosity of no greater than 5% and (iii) an open porosity of no greater than 47% and (b) graphite having the following properties (i) an x-ray density of at least 2.20 g per cubic centimetre (ii) a closed porosity or no greater than 5% and (iii) an open porosity of no greater than 25%. Also claimed are: (A) an electrode of an alkali metal/carbon electrochemical cell of improved capacity comprising (I) compacted carbon as described above consisting of coke or graphite as described above and (II) a binder; and (B) an alkali metal/carbon electrochemical cell comprising (I) an electrode comprising a binder and a compacted carbon selected from the coke or graphite described above; (II) a non-aqueous electrolytic solution comprising an organic aprotic solvent and an electrolytically conductive salt of an alkali metal; and (III) a counter electrode. |
