OXIDIZED CARBON BLACKS AND APPLICATIONS FOR LEAD ACID BATTERIES

Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. The oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100g; and at least one of the followin...

More Information
Summary:Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. The oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100g; and at least one of the following properties:(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;(b) a total oxygen content of at least 3.5 wt.% relative to the total weight of the oxidized carbon black;(c) a total titratable acidic group content of at least 0.5 µmol/m, as determined by Boehm's titration method; and(d) a total titratable acidic group content of at least 0.5 mmol/g, as determined by Boehm's titration method.
