Internal resistance dynamics reliably capture usage pattern and ambient temperature. Accurately predicting the lifetime of lithium-ion batteries in the early stage is critical for faster battery production, tuning the production line, and predictive maintenance of energy storage systems and battery-powered devices.
Internal resistance is one of the limiting factors for the output power of lithium-ion batteries. When the internal resistance of the battery is high, the current passing through the battery will result in a significant voltage drop, leading to a reduction in the battery’s output power. b. Internal resistance leads to self-discharge in batteries.
Internal resistance is one of a few key characteristics that define a lithium ion cell’s performance. A cell’s power density, dissipation, efficiency, and state of health (SoH) all depend on its internal resistance. However, a cell’s internal resistance is anything but a single, unvarying value.
Temperature plays a substantial role in influencing internal resistance. Generally, higher temperatures lead to lower internal resistance. To enhance the performance of lithium-ion cells/batteries, various measures can be employed to reduce internal resistance. Here are some common methods: 1. Optimization of Battery Materials
Conclusions This paper performed a data-driven analysis of battery internal resistance and modeled the internal resistance dynamics of lithium-ion batteries. The analysis demonstrates that battery internal resistance dynamics strongly correlate with the capacity for actual usage conditions even at the early stage of cycling.
However, the internal resistance behaves differently at different temperatures. It was shown that as the temperature increases to room temperature, the resistance of 26665 (LiFePO4) lithium-ion battery exponentially decreases and then increases again . The relation is expressed in Eq. (2).
