Sci.859 012083DOI 10.1088/1755-1315/859/1/012083 Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
Since then, 12 V lead-acid batteries have been used widely in passenger cars, vans and trucks. Consequently, batteries have become more reliable and more durable with the result that routine/regular maintenance has been largely eliminated.
The lead-acid battery system is designed to perform optimally at ambient temperature (25°C) in terms of capacity and cyclability. However, varying climate zones enforce harsher conditions on automotive lead-acid batteries. Hence, they aged faster and showed lower performance when operated at extremity of the optimum ambient conditions.
Catastrophic failure is attributed to incorrect cell design, poor manufacturing practice, abuse, or misuse. These problems are obvious and, accordingly, have been afforded little discussion. Progressive life-limiting factors encountered with flooded-electrolyte batteries are discussed in detail.
Discharging a battery at high rate causes a compact layer of tiny lead sulfate crystals to form on the surface of the negative plate. Subsequent charging gives rise to an early evolution of hydrogen and thus becomes less efficient. Hydrogen evolution is further exacerbated when a high charging current is used.
The batteries fail due to the progressive accumulation of lead sulfate mainly on the surfaces of the negative plates. The sulfate layer develops to such an extent that the effective surface area of the plate is reduced markedly such that the plate can no longer deliver the high current required by the 42 V profile.
