C is the first letter of Capacity, which is used to indicate the magnitude of the current when the battery is charged and discharged.
For example, when the rated capacity of the rechargeable battery is 1100 mAh, it means that the discharge time of 1100 mAh (1 C) can last for 1 hour. For example, the discharge time of 200 mA (0.2 C) can last for 5 hours, and the charging can also be calculated according to this comparison.
2, the termination voltage (Cut-offdischargevoltage)
When the battery is discharged, the voltage drops to the lowest operating voltage value at which the battery should not continue to discharge.
Depending on the type of battery and the different discharge conditions, the battery capacity and life requirements are also different, so the specified battery discharge termination voltage is also different.
When the battery is not discharged, the potential difference between the two poles of the battery is called the open circuit voltage.
The open circuit voltage of the battery will vary depending on the material of the positive and negative electrodes of the battery. If the materials of the positive and negative electrodes of the battery are exactly the same, then the open circuit voltage is the same regardless of the size of the battery and how the geometry changes.
4, depth of discharge (DepthofdischargeDOD)The percentage of the battery's discharged capacity as a percentage of its rated capacity during battery use is called the depth of discharge.
The depth of discharge has a deep relationship with the charging life of the secondary battery. When the depth of discharge of the secondary battery is deeper, the charging life is shorter, so deep discharge should be avoided as much as possible during use.
5, overdischarge (Overdischarge)If the battery exceeds the end voltage value of the battery discharge during the discharge process, it may cause the internal pressure of the battery to rise when the discharge continues, and the reversibility of the active materials of the positive and negative electrodes is damaged, so that the capacity of the battery is significantly reduced.
6, overcharge (Overcharge)When the battery is fully charged after charging, if it continues to charge, it may cause the internal pressure of the battery to rise, the battery is deformed, the night is leaking, etc., and the performance of the battery is also significantly reduced and damaged.
The electrical energy released by the average unit volume or mass of the battery.
Generally, in the same volume, the energy density of a lithium-ion battery is 2.5 times that of a nickel-cadmium battery and 1.8 times that of a nickel-hydrogen battery. Therefore, in the case of equal battery capacity, a lithium-ion battery will be more than a nickel-cadmium or nickel-hydrogen battery. Smaller and lighter.
8, self-discharge (Selfdischarge)The battery will cause its power loss due to various reasons, regardless of whether it is used or not.
If calculated in units of one month, the lithium-ion battery self-discharge is about 1% - 2%, and the nickel-hydrogen battery self-discharges about 3% - 5%.
9, charging cycle life (Cyclelife)When the rechargeable battery is repeatedly charged and discharged, the battery capacity gradually decreases to 60%-80% of the initial capacity.
10, memory effect (Memoryeffect)During the charging and discharging process of the battery, many small bubbles are generated on the battery plate. For a long time, these bubbles will reduce the area of ​​the battery plate and indirectly affect the battery capacity.
