Abstract
Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. In some embodiments, the oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m2/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100 g; and a volatile content of at least 5.5 wt. % relative to the total weight of the oxidized carbon black, as determined by weight loss at 950° C.
