Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

Compared to advanced lead-acid batteries, the PbC batteries: Support higher [10-20x] charge acceptance and faster recharge [5-10x] in partial state-of-charge (PSOC) applications; Offer an 4x increase in cycle life in 100% depth-of-discharge applications; and. Axion is working with the railroad on its $8B Crescent Corridor project.
