Most days, home battery systems store more energy than is consumed. As a result, the storage systems are cycled at high SOC ranges of 50 to 100 percent, which causes increased aging. To reduce the aging, system settings should delay charging the batteries until later in the day.
A case study reveals the most relevant aging stress factors for key applications. The amount of deployed battery energy storage systems (BESS) has been increasing steadily in recent years.
Lithium-ion batteries are widely used in energy-storage systems and electric vehicles and are quickly extending into various other fields. Aging and thermal safety present key challenges to the advancement of batteries. Aging degrades the electrochemical performance of the battery and modifies its thermal safety characteristics.
Current research primarily analyzes the aging condition of batteries in terms of electrochemical performance but lacks in-depth exploration of the evolution of thermal safety and its mechanisms. The thermal safety of aging batteries is influenced by electrode materials, aging paths, and environmental factors.
Reliably predicting battery aging remains a challenging endeavor. Newly developed battery systems are therefore extensively tested by electrically cycling them for months to years. This final validation comes at the end of a streamlined development process in which the longevity of the battery must be ensured at a significantly earlier stage.
But, in general, batteries age faster if they are used. To manage the complexity, it is common practice to split aging into three buckets: calendric, cyclic, and reversible aging: Calendric aging – The gradual degradation of batteries over time, even if they are not used.
