PowerGenix claims its nickel-zinc chemistry offers a number of advantages over lead-acid batteries.

PowerGenix announced on July 31 that it has entered into an innovation contract with PSA Peugeot Citroën Automobiles of France for evaluation of the supplier's nickel-zinc batteries as a replacement for lead-acid types in stop-start vehicles. Stop-start technology already has been widely deployed in Europe, where 70% of all vehicles sold by 2017 are expected to carry the system as a standard feature, according to PowerGenix. It says lead-acid batteries, the most common battery choice, are low-cost, easily available, and relatively safe. Ni-Zn batteries, with higher energy density and higher charge acceptance, could be an alternative choice offering a sustained fuel-economy improvement. PSA and PowerGenix will work closely together to verify several aspects of performance improvements, including high sustained charge acceptance, weight savings, and service life improvements for use in stop-start vehicle applications. The two companies also will investigate battery sizing, cost projections, in-service life evaluation, and safety analysis of the batteries, with tests performed under wide temperature ranges. At completion of the contract term, PowerGenix Ni-Zn batteries are expected to be fully tailored for Peugeot and ready for successful integration into vehicles.
