摘要：

Two types of activated carbon tablets (AC tablets) were prepared and characterized by adsorption methods for electric double-layer capacitors. The tablets were prepared from either the activation or carbonization of molded mixtures comprising phenolic resin-based activated carbon powders and phenolic resins. The specific surface area of the tablets (a) prepared from activation was 2010 m2g-1 and the bulk density was 0.45 gcm -3. The area of tablets (b) from carbonization was 1400 m 2g-1 with a yield of 83% (weight of obtained tablets/weight of molded mixtures). The capacitance of the capacitors with tablets (a) showed 7.3-12.5 F/(cm3 of AC tablets). The reliability of the capacitors with AC tablets (a) and (b) was improved in comparison with that of capacitors with polarizable electrodes comprising activated carbon powders and binders. © 1990 The Chemical Society of Japan.
