AI Customer ServiceInternal 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.
For example, a high-performance lithium-ion cell designed for high-rate discharge applications may have an internal resistance of around 50 mΩ, while a lower-performance cell designed for low-rate discharge applications may have an internal resistance of around 200 mΩ.
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.
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
