In this research, we investigate how temperature variations and cycling impact the state of charge (SOC) degradation of Li-ion and lead-acid batteries over an extended period and the other system components performances.
Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs)—lead–acid batteries are made from abundant low-cost materials and nonflammable water-based electrolyte, while manufacturing practices that operate at 99% recycling rates substantially minimize environmental impact .
Capacity degradation is the main failure mode of lead–acid batteries. Therefore, it is equivalent to predict the battery life and the change in battery residual capacity in the cycle. The definition of SOH is shown in Equation (1): where Ct is the actual capacity, C0 is nominal capacity.
The technical challenges facing lead–acid batteries are a consequence of the complex interplay of electrochemical and chemical processes that occur at multiple length scales. Atomic-scale insight into the processes that are taking place at electrodes will provide the path toward increased efficiency, lifetime, and capacity of lead–acid batteries.
Availability, safety and reliability issues—low specific energy, self-discharge and aging—continue to plague the lead-acid battery industry, 1 – 6 which lacks a consistent and effective approach to monitor and predict performance and aging across all battery types and configurations.
Implementation of battery management systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life. Perhaps the best prospect for the unutilized potential of lead–acid batteries is electric grid storage, for which the future market is estimated to be on the order of trillions of dollars.
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.
Accidental inclusion of LIBs in lead battery recycling has proven hazardous, and better safety and recyclinge protocols are needed. The technical challenges facing lead–acid batteries are a consequence of the complex interplay of electrochemical and chemical processes that occur at multiple length scales.
