What kind of low-temperature lithium battery is better?

As the domestic low-temperature cold region is not many, Battery recycling line low-temperature battery manufacturers are not many, but foreign countries such as Russia, the United States, Canada and other Nordic countries, the demand for low-temperature lithium-ion battery is greater. So what is cryogenic lithium-ion battery? Here's how:

Low-temperature lithium-ion batteries mainly include low-temperature lithium polymer,lithium battery welding machine low-temperature 18650 lithium-ion battery and low-temperature lithium iron phosphate battery, each with its own advantages and disadvantages.

low temperature polymer lithium battery

Low temperature li-polymer should be one of the best in low temperature performance,mounting machine especially in the management of smart wearable technology equipment, which is a better advantage than China.

Low temperature polymer lithium battery

Low temperature performance characteristics:

At present, the low-temperature polymer lithium-ion battery of the claw battery can reach the temperature range of the following stages:

In the temperature range of -50℃ to 50℃, the effective discharge capacity can reach more than 75% at 0.2C rate. The effective cycle life is 150 to 200 times.

The effective discharge capacity of 0.2 ° C is more than 85% and that of 0.5 ° C is more than 75% in the temperature range of -40 ~ 60 ° C

In the temperature range of -30℃ to 65℃, the discharge rate is 0.2C, the effective discharge capacity is more than 90%, the discharge rate can reach 2C, and the discharge capacity is more than 75%. Effective cycle life of more than 300 times.

Within the temperature control range of -20 ~ 75 ° C, the 0.2 C discharge can effectively increase the emission environmental capacity by more than 95% , and the 5c discharge can be truly realized, and the emission data capacity can be effectively utilized by more than 65% , effective development of more than 300 times the life of the circulation system.

Due to the complexity and non-uniformity of the use environment, the above basic data will be biased due to specific use.

the advantages of adapting to the space requirement of equipment.

At present, colloidal or solid-state lithium batteries are mainly used in low-temperature li-polymer, and the production process is lamination. Therefore, the low-temperature li-polymer can be more flexible in the design and manufacture of battery capacity and shape, and can be basically customized. Especially in small ultra-thin batteries, it has more advantages. At present, this kind of portable electronic equipment or smart wearable equipment, which is widely used, is the first choice for batteries, especially in extreme cold adventure equipment.

In terms of product weight, calculated by colloidal or solid electrolyte, low-temperature lithium polymer batteries are basically the same as low-temperature lithium iron phosphate batteries, and under the same voltage and capacity, they are lighter than low-temperature 18,650 lithium-ion batteries.

Lithium batteries for electric cars are too expensive. Can lead-acid batteries be used instead of lithium batteries for electric vehicles?

How long will the lithium-ion battery in 1865 last?

The price of 18650 lithium-ion power battery, the capacity of the battery is getting larger and more expensive?
