Each aging mechanism has an impact on the behavior of the battery. The impact can be broken down into two performance parameters: capacity and internal resistance. Batteries lose capacity when they age. For an electric vehicle, losing capacity means the EV cannot drive as far as it used to without stopping for a recharge.
His personal passion is Martial Arts: mixed martial arts, luta livre, grappling, boxing and Brazilian jiu-jitsu. Battery aging is complex, non-linear and influenced by many factors. It is common to split aging into three buckets: calendric, cyclic, and reversible aging.
The aging of lithium-ion batteries is a complex process influenced by various factors. The aging manifests primarily as capacity and power fades . Capacity fade refers to the gradual reduction in the battery’s ability to store and deliver energy, resulting in a shorter usage time.
One reason is that charging a battery with high power raises the temperature, which leads to accelerated aging. Another reason is the increased risk of lithium plating. Besides temperature, charging power, throughput, and depth of discharge, other effects such as phase shifts also accelerate battery aging.
The main drivers of calendric aging are temperature and state of charge (SOC). Overall, at higher temperatures and SOCs batteries age faster. An average decrease of 10°C or 50°F can double a battery’s lifespan as illustrated in Figure 2. However, remember not to operate your batteries at too low temperatures because of lithium plaiting.
Performance degradation is common to all battery technologies. Failure and gradual performance degradation (aging) are the result of complex interrelated phenomena that depend on battery chemistry, design, environment (temperature), and actual operation conditions (discharge rate, charge protocol, depth of discharge, etc.).
Battery aging is complex, non-linear and influenced by many factors. It is common to split aging into three buckets: calendric, cyclic, and reversible aging.
