How Resistance, Temperature, and Charging Behaviors Impact Battery

A battery''s self-discharge rate refers to how a battery loses charge and energy over time, even when the battery is idle or disconnected from a power source. This is a natural phenomenon that varies with battery chemistry and temperature, with rechargeable batteries (e.g. Li-ion and NiMH) discharging much more quickly than non-rechargeable batteries (e.g. alkaline).

Relationship between battery temperature and discharge power [PDF]

6 FAQs about [Relationship between battery temperature and discharge power]

How does temperature affect battery discharge capacity?

When the ambient temperature is higher than 25 °C and lower than 55 °C, the discharge capacity of the battery will increase as the temperature rises. This is due to the increase in the activity of the internal materials of the battery, the faster the deintercalation of lithium ions, as well as the decrease in internal resistance.

How does temperature affect battery power & energy output?

When the temperature decreases, the internal resistance of the battery increases, the electrochemical reaction speed slows down, the internal polarization resistance increases rapidly, and the discharge capacity and discharge platform decrease, which affects the battery power and energy output.

How does temperature affect lithium ion battery discharge?

On the one hand, the decrease in temperature will result in a decrease in the activity of the active electrolyte in the lithium ion battery and an increase in the concentration, which in turn will slow down the deintercalation rate of lithium ions during the discharge process [ 27 ].

How does temperature change in a battery?

It can be seen from the figure that at different discharge rates, the temperature rise of the battery body has the same trend as that of the positive and anode lugs: the temperature rises rapidly in the initial stage of discharge, rises slowly in the middle stage, and rises rapidly again in the later stage of discharging.

How does discharge rate affect battery characteristics?

As a key factor, discharge rate has a great influence on battery characteristics. Therefore, it is particularly important to study the characteristics of LIB at different discharge rates. Battery discharge is the process of converting chemical energy into electrical energy and releasing the energy to the load.

What temperature should a battery be discharged?

The batteries have an operating range of -18°C to 55°C, but are recommended to discharge at 20±2°C. Under the optimal temperature conditions and with a 10Ω load, the battery is expected to reach its cutoff voltage defined at 0.9V in 480 minutes. Figure 2 shows the manufacturer's schematic diagram of discharge under these conditions.
