Patent ID: 7445870

Claim:
An organic electrolyte cell comprising: a positive electrode comprised of an electrode substrate and an active material layer formed thereon, a negative electrode comprised of an electrode substrate and an active material layer formed thereon, and an organic solvent solution prepared by dissolving a salt in an aprotic organic solvent, said organic solvent solution present between the active material layers of the positive electrode and the negative electrode facing each other, wherein the active material layer of each positive and negative electrode is made from the same insoluble and non-fusible substrate that contains a polyacene skeletal structure having an atomic ratio of hydrogen atoms/carbon atoms in a range from 0.50 to 0.05, has a thickness in a range from 0.01 to 16 μm, and contains particles of which 80% by weight fall in a range from 0.5 to 6 μm of the particle size distribution, wherein the value of τ, the product R·C of an impedance R(Ω) and a capacity C(F), is set in a range from 0.00002 to 0.05.
