What is the role of the self discharge internal resistance of high-temperature batteries?

The self discharge internal resistance of high-temperature batteries plays an important role in the performance and lifetime of batteries.

High temperature batteries typically operate at temperatures above 60 ° C, which can cause batteries to self discharge faster than batteries operating at lower temperatures. The self-discharge rate of a battery is determined by its internal resistance, which is the resistance to the flow of current within the battery.

High self-discharge rates can be a problem for high-temperature batteries because they can lead to faster loss of charge when not in use. This may result in a decrease in battery capacity and overall performance.

In addition, a high self-discharge rate increases the likelihood of overheating and damage to the battery, especially during prolonged storage or non use. The internal resistance of a battery can affect the rate of heat generation inside the battery, leading to thermal runaway and other safety hazards.

Therefore, managing the self-discharge internal resistance of high-temperature batteries is crucial to maintaining their performance, reliability, and safety. This may involve strategies such as optimizing battery design and materials, implementing effective battery management systems, and monitoring battery temperature and charging status.
