Specific meaning of common technical parameters of 4LR44 battery
Common technical parameters of 4LR44 battery. When choosing a 4LR44 battery, you should select a specific type of 4LR44 battery according to the field of 4LR44 battery application or the recommendations of the lithium battery manufacturer, such as rack UPS or tower UPS for the computer room. What should you do after selecting the type of 4LR44 battery? Then you need more specific parameters.
Let's talk about the parameters that people usually look at when checking 4LR44 battery. I believe that many people have seen and heard a lot about these parameters, so they have a general understanding of their meaning, but they still don't know much about their definitions. Now let the editor of Storage Energy Electric collect and organize their specific meanings for everyone to see. The following definitions are mainly collected from Baidu Encyclopedia.
Battery capacity
Battery capacity is one of the important performance indicators for measuring battery performance. It indicates the amount of electricity discharged by the battery under certain conditions (discharge rate, temperature, termination voltage, etc.) (JS-150D can be used for discharge test), that is, the capacity of the battery, usually in ampere hours (abbreviated as A·H, 1A·h=3600C).
Battery capacity is divided into actual capacity, theoretical capacity and rated capacity according to different conditions. The calculation formula of battery capacity C is C=∫t0It1dt (integrate the current I from t0 to t1), and the battery is divided into positive and negative poles.
Nominal voltage
Nominal voltage is a professional term in physics, which refers to the voltage value corresponding to the nominal working current of the voltage-stabilizing thermistor at +25℃. The most commonly used nominal voltage of the voltage-stabilizing thermistor is 2 volts, and others include 3 volts, 4 volts, 5 volts, 6 volts, etc. The nominal voltage is also an appropriate voltage approximation to indicate or identify a battery, also known as the rated voltage, which can be used to identify the battery type.
The nominal voltage of the battery is an appropriate voltage approximation to indicate or identify a battery, also known as the rated voltage, which can be used to identify the battery type. For example, the open circuit voltage of a lead-acid battery is close to 2.1V, and the nominal voltage is 2.0V. The nominal voltage of zinc-manganese dry batteries is 1.5V, the nominal voltage of nickel-cadmium batteries and nickel-metal hydride batteries is 1.2V, and the nominal voltage of lithium-ion batteries is 3.7V.
In fact, the nominal voltage does not refer to the battery voltage. The actual voltage of the battery changes according to the actual capacity of the battery. The nominal voltage of the same battery in the market may be different in different scenarios or regions, but the battery's voltage does not change.
Battery internal resistance
The internal resistance of a battery refers to the resistance encountered by the current flowing through the battery when the battery is working. It includes ohmic internal resistance and polarization internal resistance. Polarization internal resistance includes electrochemical polarization internal resistance and concentration polarization internal resistance.
For lithium-ion batteries, the battery internal resistance is divided into ohmic internal resistance and polarization internal resistance. Ohmic internal resistance is composed of electrode materials, electrolytes, diaphragm resistance and contact resistance of various parts. Polarization internal resistance refers to the resistance caused by polarization during electrochemical reactions, including resistance caused by electrochemical polarization and concentration polarization.
The actual internal resistance of a lithium-ion battery refers to the resistance encountered by the current flowing through the battery when the battery is working. The internal resistance of the battery is large, and (during normal use of the battery) a large amount of Joule heat will be generated (according to the formula: E=I^2RT), causing the battery temperature to rise, resulting in a decrease in the battery discharge working voltage and a shortened discharge time, which has a serious impact on the battery performance and life.
The precise calculation of the internal resistance of the battery is quite complicated, and it will continue to change during the use of the battery. According to experience, the larger the volume of the lithium-ion battery, the smaller the internal resistance; vice versa.
Self-discharge rate
The self-discharge rate, also known as the charge retention capacity, refers to the ability of the battery to retain the amount of electricity stored in the battery under certain conditions when the battery is in an open circuit state. It is mainly affected by factors such as battery manufacturing process, materials, and storage conditions. It is an important parameter for measuring battery performance.
The size of the self-discharge, that is, the self-discharge rate, is related to the solubility of the positive electrode material in the electrolyte and its instability after heating (easy to self-decompose). The self-discharge of rechargeable batteries is much higher than that of primary batteries. Moreover, the monthly self-discharge rate of the battery is different for different battery types. It generally varies between 10-35%. During storage, the self-discharge is accompanied by an increase in the internal resistance of the battery, which will cause the battery load capacity to decrease. When the discharge current is large, the energy loss changes significantly.
It is not enough to judge the performance of the 4LR44 battery by looking at the value of one of these parameters alone. Other technical parameters should also be referred to to comprehensively evaluate the performance of the selected 4LR44 battery.
