What is the capacity of lithium battery tape?

1. What is the capacity of lithium battery tape?

LithiumBattery TapeThe capacity of can be divided into additional capacity and actual capacity. Battery extra power refers to the amount of power that should be discharged regularly or under certain discharge conditions when designing and manufacturing batteries. Lithium-ion ordinary battery at room temperature constant current (1C) constant voltage (4.2V) charging conditions for 3h. The actual capacity of the battery refers to the actual power of the battery discharged under certain discharge conditions, which is mainly affected by the discharge rate and temperature (strictly speaking, the battery capacity should indicate the charging and discharging conditions). Common capacity units are: mAh and Ah = 1000mAh).

2. What is the battery internal resistance?

Lithium battery tape refers to the current resistance flowing through the battery when the battery is working. It consists of ohmic internal resistance and internal resistance. The high internal resistance of the battery will cause the voltage drop of the battery discharge operation and shorten the discharge time. The internal resistance is mainly affected by the data, manufacturing process and structure of the battery. It is an important parameter to measure the performance of the battery.

3. What is the open circuit voltage?

Refers to the potential difference between the positive and negative electrodes of the battery when the battery is in a non-working state, that is, when no current flows through the circuit. Generally, the open circuit voltage of lithium ion is about 4.1-4.2V after full charge, and about 3.0V after discharge. The lithium battery tape can judge the charging state of the battery through the open circuit voltage of the battery.

4. What is the working voltage?

Also known as terminal voltage, it refers to the potential difference between the positive and negative electrodes of the lithium battery tape when the battery is working, that is, when the current in the circuit expires. In the battery discharge working state, when the current flows through the battery, there is no need to overcome the resistance caused by the internal resistance of the battery, so the working voltage is always lower than the open battery, and the opposite is true when charging. The discharge voltage of lithium ion is about 3.6V

5. What is the discharge channel?

The lithium battery tape discharge channel is to stop constant voltage charging when the voltage is 4.2V and the current is less than 0.01C, then stand for 10 minutes, and discharge to 3.6V at any discharge current. It is an important measure of battery quality.

What is the (charge/discharge) rate?

Refers to the current value required by the lithium battery tape battery to discharge its extra capacity within a specified time. The data value is equal to a multiple of the extra capacity of the battery, usually expressed by the letter C. For example, the nominal extra capacity of the battery is 1C(1 rate) at 600 mA, 0.5c at 300 mA, 10C at 6a(600 mA), and so on.

7. What is the self-discharge rate?

Also known as charging sustainability, it refers to the sustainability of the battery under certain conditions when the lithium battery tape is in an open circuit state. Mainly affected by the battery manufacturing process, data, storage conditions and other factors. It is an important parameter to measure the performance of the battery.

8. What is internal pressure?

Refers to lithiumBattery TapeThe internal pressure is caused by the gas generated during the charging and discharging of the sealed battery, and is mainly affected by the battery data, manufacturing process, battery structure and other factors. The main reason is that the moisture in the battery and the gas generated by the differentiation of the organic solution accumulate in the battery.
