How does Ni-Cad Battery perform under different temperature conditions?
The performance of Ni-Cad Battery is affected by temperature changes, which is particularly significant in low and high temperature environments. In a low-temperature environment, the conductivity of the battery decreases and the fluidity of the electrolyte becomes worse, causing the internal reaction rate of the battery to slow down. This can lead to a weakening of the battery's ability to discharge, manifesting as reduced discharge capacity. Under low temperature conditions, the electrochemical reaction in the battery is restricted by temperature, and the migration speed of electrons and ions slows down, thus affecting the overall performance of the battery.

On the contrary, in high temperature environment, the electrolyte fluidity of Ni-Cad Battery increases, which helps to improve the discharge performance of the battery. This is because high temperature promotes the migration of ions in the electrolyte and accelerates the chemical reaction between the positive and negative electrodes. However, high temperature environments also bring a series of challenges. One of the main issues is an increase in self-discharge, which is the rate at which a battery discharges itself when not in use. This can result in a loss of energy from the battery, affecting its cycle life.

In practical applications, the temperature during charging is also a factor that needs to be considered. Charging temperatures that are too high or too low can cause problems. At excessively high temperatures, gas production inside the battery may increase, causing pressure to rise, leading to safety issues. On the contrary, during charging, too low temperature may reduce the fluidity of the electrolyte, restrict the internal reactions of the battery, and affect the charging efficiency.

However, in some special application scenarios, such as extreme high or low temperature environments, some special design measures or other equipment may be required to ensure that the battery can work properly. This may include the use of temperature regulation devices, the use of insulation materials, etc. to improve battery stability and performance.
