Abstract
An lead-acid battery is described. The battery includes a carbon fiber electrode having a paste containing a novel additive including one or more carbons, organic expanders, and barium sulfate.
Claims19
An electrode comprising a carbonized fiber current collector having a paste with an additive that improves charge acceptance, with the additive having components, the components consisting of:
- an organic expander;
- barium hydroxide;
- and
- ultrafine barium sulfate, with the ultrafine barium sulfate having a particle size range from 0.04 micrometers to 0.8 micrometers and having an amount of nucleation sites greater than a second amount of nucleation sites for a barium sulfate having a particle size range greater than 1 micrometer for a charge acceptance greater than the barium sulfate having the particle size range greater than 1 micrometer.

A lead-acid battery, comprising:
- a carbon fiber current collector having an electrochemically active material and a fiber mat portion, the electrochemically active material having one or more additives, with at least one of the one or more additives having components, the components consisting of:
- an organic expander
- barium hydroxide;
- and
- ultrafine barium sulfate, with the ultrafine barium sulfate having a particle size range from 0.1 microns to 0.8 microns and having an amount of nucleation sites greater than an second amount of nucleation sites for a barium sulfate particle having a particle size range greater than 1 micron for a charge acceptance greater than the barium sulfate particle having a particle size range greater than 1 micron;
- and
- the fiber mat portion having a plurality of carbonized fibers.
