Use of carbon black as a substitute for acetylene black for pasted dry cells

Acetylene black (AB) is the preferred carbon material due to its desirable properties and characteristics, especially in the case of paperlined cells where no electrolyte reservoir is present. However, in the present study it has been found that carbon black can be substituted for AB in pasted dry cells where an electrolyte reservoir is present in the form of the paste. Comparative studies (discharge behaviour) with a standard market product reveals that equivalent or even better discharge performance/life can be obtained using carbon black as a replacement but with modified and optimized composition of the black mix
