All batteries age and the effects manifest themselves in diminished capacity, increased internal resistance and elevated self-discharge. A new battery (Figure 1) delivers (or should deliver) 100 percent capacity; an aged unit (Figure 2) may hold only 20 percent. In our example, the capacity loss is illustrated by placing rocks in the container.
In , the effect of current rate on the aging is analyzed cycling the battery at different current rates. Anyway, even if the tests are performed in a climatic chamber at 25 °C, the temperature of the battery cell is not controlled and will change with the current rate due to its internal losses.
A new battery (Figure 1) delivers (or should deliver) 100 percent capacity; an aged unit (Figure 2) may hold only 20 percent. In our example, the capacity loss is illustrated by placing rocks in the container. Capacity is represented by a liquid with no obstruction. The battery delivers full runtime. Capacity loss is illustrated as “rock-content.”
Lithium-ion batteries are constantly degrading—even when they’re not in use—simply as a consequence of time and thermodynamics. This is referred to as calendar aging Battery calendar aging is the effects of time on battery health.
Battery calendar aging is the effects of time on battery health. Batteries degrade over time, even when they are not cycled, especially while under high temperature and/or high voltage conditions. Overall battery longevity is determined by a combination of cycle aging and calendar aging effects.
In any case, according to the particular aging mechanism the battery can decrease its capacity (capacity fade) and/or increases its internal resistance (power fade). Furthermore, the aging mechanisms can differ for different kind of lithium ion battery chemistries , .
