Talk about the difference between lithium battery and storage battery.

Difference between the battery and lithium-ion battery; Prices vary. Lithium-ion batteries are expensive; Safety performance. High battery safety; Use time is different. The service time of a lithium-ion battery is relatively long.; Lithium-ion batteries are better than batteries. Although most electric vehicles now use batteries because of price problems, lithium-ion batteries can completely replace lead-acid batteries.

Failure classification and cause analysis of lithium battery.

Failure classification and cause analysis of lithium battery.

1、 Capacity decay failure
During the standard cycle life test, the discharge capacity shall not be less than 90% of the initial capacity when the number of cycles reaches 500. Or when the number of cycles reaches 1000, the discharge capacity shall not be less than 80% of the initial capacity. If the capacity drops sharply within the range of standard cycles, it belongs to capacity attenuation failure.

Difference between 26650 lithium batteries and 18650 lithium batteries?

The battery life of the 18650 lithium-ion battery and 26650 lithium-ion battery must be different because the two models are named after size, 18650, that is, straight 18mm and height 65mm. From this point of view, 26650 must have a larger volume ratio than 18650, so there is a larger space-filling material to achieve a larger capacity. At present, the capacity of 18650 is 220026003100mah, while the capacity of 26650 is generally 40004204500mah, The lead-in endurance will be longer.

What are the reasons for the bulging of lithium batteries in electric vehicles?

Battery is the core component of electric vehicle. The word "lithium ion battery" is familiar to motorists. In recent years, the phenomenon of battery bulging is common, which makes many consumers very distressed. Because once there are individual battery bulges in a group of batteries, the whole group of batteries must be replaced.

How does the charger judge the charging condition of the lithium battery?

General chargers are constant current charging. Smart lithium-ion battery chargers usually take some time rather than immediately determining whether the battery has just been fully charged.

What effect does the overcharge of lithium batteries have on performance?

1) In the polarization phase, the voltage of the battery rises rapidly after the current is applied due to the existence of polarization, and the temperature of the battery decreases at this time;

2) After 240s, the battery enters the stage of stable temperature rise, in which the battery temperature rises at the rate of 0.05 ℃ /min;

3) During the temperature stabilization phase, the battery temperature will continue to rise, but the battery temperature will not rise.

18650 lithium battery pack with large internal resistance or small internal resistance?

Is the internal resistance of 18650 battery pack large or small? Resistance indicates the resistance of a circuit element to current transmission. The unit is Ohm. The internal resistance of 18650 battery pack is related to the capacity and type of battery. Generally speaking, the larger the capacity, the smaller the internal resistance. For batteries with the same capacity, the internal resistance of the multiple type is smaller than that of the capacity type. The internal resistance of a typical lithium battery pack is only a few milliohms.

We should choose 18650 Lithium ion battery pack with large internal resistance or small?

In a lithium-ion battery, the lithium ions move from one pole to another, and the factors that hinder the movement of the ions together form the internal resistance of the lithium-ion battery.  The important part includes the physical resistance of conductive parts;  Intrinsic impedance of electrochemical materials such as motor materials, diaphragms and electrolytes;  There is a temporary increase in the battery internal current through the movement of lithium ion obstruction;  These three parts together constitute the main body of internal resistance.
