Patent ID: 8043532

Claim:
A composition for electrodes, comprising: about 5 to about 95% by weight of comprising aluminum powder, the aluminum powder having a particle size distribution of about 2.0 or less as expressed by the following Equation (1) Particle size distribution=( D 90 −D 10)/ D 50 Equation (1) wherein D 10 , D 50 , and D 90 represent particle diameters at 10%, 50% and 90% points on an accumulation curve of a particle size distribution when the total weight is 100% D 90 −D 10 is 3.58 μm to 10.42 μm, and having D 50 in the range of about 0.1 μm≦D 50 ≦ about 20 μm; about 3 to about 60% by weight of an organic binder; and the balance of a solvent.
