Internal Resistance Increase

Internal resistance, a measure of the opposition to current flow within the battery, rises over time, reducing the efficiency of energy transfer. This increase in internal resistance is often associated with the build-up of degradation products, the growth of passivation layers, and changes in the electrode structure. Higher internal resistance results in increased energy loss during operation, leading to reduced performance and potentially causing thermal issues.

This is particularly relevant during high-current demands, such as acceleration or high-power use.

Thermal Runaway

Thermal runaway is a critical concern in battery technology. It represents a rapid and uncontrolled temperature increase, potentially leading to catastrophic failure. The chain reaction begins when an initial heat source, perhaps due to a manufacturing defect or an internal short circuit, triggers a cascade of events, resulting in a significant temperature rise. This rapid temperature escalation can cause thermal degradation of the battery materials, triggering exothermic reactions, and ultimately leading to a thermal runaway event.
