MOLECULAR REBAR® is a performance-enhancing battery additive comprised of discrete carbon nanotubes (dCNT), which are uniformly distributed within negative and/or positive battery pastes via an aqueous dispersion. The addition of MOLECULAR REBAR® simultaneously improves electrical performance and bolsters active-material strength. By providing more efficient charging and structural durability, batteries with MOLECULAR REBAR® are better able to withstand aggressive cycling requirements ― both deep-cycle and partial state-of-charge (PSoC) ― by overcoming deficit charging and suppressing both sulfation and material shedding/growth. The products are easily incorporated into existing pasting lines without changes to mixing, grid preparation, or curing, and have yielded pronounced benefits in commercial batteries at dozens of customer sites in numerous applications around the world. As discussed in the presentation, the following benefits have been found from production trials with MOLECULAR REBAR®: (i) Improved capacity retention with fixed charging protocols with the additive; (ii) Improved CCA duration with the additives in the negative; (iii) Significant improvements in cycle life (15%-80% increase in durability under JIS 8702 cycling protocol); (iv) electric-rickshaw operators, who use flooded tubular batteries, have reported more robust operation, which allows for more vehicle miles driven per day with less watering.
