Abstract
The factors which limit the rate and completeness of the charge and discharge processes of battery systems at low temperature are discussed: low concentration of reactants, low fluidity and relaxation rate of electrolyte, low nucleation and growth rate of reaction products, low ionic- vs. semi-conductivity of reaction products, and low average pore size in the plates. Systems based on water, ammonia and aprotic solvents were reviewed. For the better -40C performers an attempt is made to identify the most important kinetic barrier to improved electrochemical performance of the system. It is noted that definitive experimental information at -40C is still scarce.
