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
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.
To reduce internal battery resistance, maintain proper charging practices, avoid high discharge rates, and operate the battery within its recommended temperature range. Additionally, ensuring good contact between cell components and using high-quality materials during manufacturing can help reduce resistance.
The internal resistance of a lithium battery can be measured using specialized equipment like battery analyzers or dedicated internal resistance meters. These devices apply a small known current to the battery and measure the voltage drop across it to calculate internal resistance.
If the internal resistance of the battery cell is not provided by the manufacturer, as we’ll see in this article, using the discharge characteristics of the battery cell, we can calculate the internal resistance of the battery cell, for a specific state of charge value.
