Extract

Concurrent with impressive advances in advanced batteries operating at high temperatures such as the Na/Na2 Sx and Li/FeS systems, have been concerns over safety and reliability of such batteries. Accordingly, various efforts have been made to offer alternative high specific energy/power batteries operating at reduced temperatures [ 1, 2, 3 ]. However, since electrode kinetics and mass transport processes in batteries are thermally activated, lower temperature systems often present a compromise between lower power output, and enhanced reliability, safety, and economic factors. Fortunately, lower temperature systems also offer far more flexibility in cell design, allowing geometries with higher electrode surface area than would be feasible with high temperature systems, thereby reducing the necessary current densities for acceptable power output.
