Battery internal resistance is the opposition to the flow of current within the battery. For many years, batteries were often assumed to be ideal voltage sources. In simple terms, this means that the battery would always provide a constant voltage regardless of the load connected to it.
One approach to calculating internal resistance involves the voltage drop method. Start by measuring the open-circuit voltage of the battery. Then, apply a known load (a resistor or device with a general resistance) to draw current from the battery. Measure the voltage across the battery terminals while the load is connected and drawing current.
The greater the internal resistance, the more significant the voltage drop. To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery’s internal resistance.
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.
