Understanding Alkaline Battery Performance in High-Drain vs. Low
This characteristic is a double-edged sword: while it limits the battery''s efficiency in high-drain applications, it also prolongs the battery''s life in low-drain scenarios.

How does current rate affect the electro-thermal behavior of batteries?
As is already known, current rate as one of the most important parameters of LIB, significantly affects the electro-thermal behaviors of batteries. 19 – 22 A high current rate usually brings about a severe temperature rise, non-uniformity and degradation; therefore, a deteriorated thermal hazard and accelerated aging may be induced.
How does current rate affect battery degradation?
Therefore, nearly all the over-discharged batteries present a linear degradation rate as the over-discharge cycling proceeds, 0.05%/cycle. The impact of current rate on the degradation is revealed by influencing the cycle time, whereby a high current rate usually brings about a shorter cycle time and further accelerates the degradation.
What happens if the temperature of a battery reaches a high value?
When the temperature of the battery reaches a high value, the thermocouple will not work; therefore, the T H will not be recorded after 220.50 °C. The temperature increases at a low rate just before the thermal runaway is induced. After thermal runaway begins (T I = 208 °C), the temperature increases very quickly.
Why do batteries have low internal resistance?
Batteries designed for high-drain applications, such as those used in electric vehicles or power tools, are often engineered specifically to have low internal resistance to optimize performance and efficiency. Managing internal resistance is vital for maximizing battery life and performance. Here are some practical tips:
How does temperature affect lithium ion batteries?
As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
How does internal resistance affect battery performance?
Internal resistance is a crucial factor in the performance of 18650 and 21700 batteries. It refers to the opposition that a battery presents to the flow of current within itself, affecting efficiency, heat generation, and overall performance. Lower internal resistance typically leads to better performance and longer battery life.
