David Boden takes a closer look at Carbon atomic number 6, the key to solving the problems of negative plate sulfation.
Carbon black has been used in the negative plates of lead acid batteries for many years. It is used as a component of the expander and the amount used is generally in the range of 0.1% to 0.2% of the negative active material weight.
There has been much speculation over the years about the role of this material but it is generally believed that it gives the pasted, cured plate improved conductivity to . . .
