1. What is a lithium ion battery?
It refers to a rechargeable battery that uses lithium ions as a reactive substance. When the battery is discharged to the termination voltage, it can be recharged to return to the state before discharge.
2. How does the lithium ion battery work?
At the time of discharge, lithium in the intercalation compound of lithium and carbon dissolves from the negative electrode to form lithium ions into the electrolytic solution, passes through the electrolytic solution, and is embedded in the positive electrode crystal to form an intercalation compound. Upon charging, the lithium ions embedded in the positive electrode are returned to the electrolyte, and then an intercalation compound is formed on the negative electrode with carbon, and is repeated.
3. What are the advantages of lithium ion batteries compared to nickel/cadmium, nickel/hydrogen, and lead-acid batteries?
High specific energy, low self-discharge rate, good high and low temperature performance and long charge and discharge life.
4. What is the average voltage of the battery?
The average value of the voltage from the start to the end of discharge when the battery is discharged.
5. What is the energy density of the battery?
Refers to the electrical energy contained in the unit volume of the battery.
6. What is the capacity of the battery?
The electric energy that the active substance in the battery participates in the electrochemical reaction is called the capacity of the battery.
7. What is the design capacity of the battery?
The capacity of the battery from the electrochemical theory is referred to as the design capacity based on the amount of active material contained in the battery.
8. What is the rated capacity of the battery?
It means that after the battery is designed, the process of making the battery should be the first one, and the capacity that the battery can reach is called the rated capacity.
9. Working temperature range of lithium ion battery?
Charging -10 - 45 ° C discharge -30 - 55 ° C
10. What is the rate of discharge of the battery?
Refers to the relationship between the discharge current (A) and the rated capacity magnification when discharging.
