What does ICR mean in battery cell? Such as: ICR18650. . . . .

ICR is a 3.7V ICR18650 rechargeable lithium-ion cylindrical battery

Among them:

I: Lithium takes the letter I in English

R: cylindrical type

Lithium ion batteries are divided into different types of positive materials such as: lithium manganate (IMR 3.6V), Lithium Cobalt Oxide (3.7V/3.8V ICR), Lithium Nickel Cobalt Manganate (commonly known as Ternary, 3.6V NCR), Lithium Iron Phosphate (3.2V V IFR), lithium titanate (2.3V/2.4V LTO) and other material system batteries, Battery cells of different material systems have different voltage platforms, safety factors, number of cycles, energy density ratios, operating temperatures, etc.

What is an IMR battery and how is it different from lithium batteries? I hope friends who know can explain it.

INR means: lith batteryium-ion in ternary material;

ICR means: lithium-ion battery in lithium cobalt oxide material;

Two They are all lithium-ion batteries with a voltage of 3 .7V, but the hardware system is different, such as common 18650 lithium-ion battery; ICR is a 3.7VICR18650 cylindrical rechargeable lithium-ion battery;

Among them:

I: Lithium takes the letter I in English.

C: Lithium cobalt oxide takes the letter C.

R: Cylindrical type.

Lithium-ion electronics are divided into different types of positive materials such as: lithium manganate (3.6 VIMR), lithium cobalt oxide (3.7 V/3, 8VICR), lithium-nickel-cobalt manganate (commonly known as ternary, 3.6 VNCR), lithium iron phosphate (3.2 VIFR), lithium titanate (2.3 V/2.4 VLTO ) and other battery cells with various material systems. The voltage platform, the safety factor, the number of cycles and thensity of batteries with different material systems. ratio, operating temperature, etc. are different. Ternary lithium battery is a type of lithium battery. Another type such as Panasonic NCR18650 is lithium cobalt oxide battery.

There is no difference between a lithium-lithium manganate battery and a lithium battery. IMR is a lithium manganate battery, which is a lithium battery cathode material.

Lithium batteries generally come in two shapes: cylindrical and square. The internal structure of the battery is a spiral winding structure, with very thin, highly permeable polyethylene film insulating material separated between the positive and negative electrodes.

The positive electrode comprises a current collector composed of lithium-cobalt oxide (or lithium-nickel-cobalt manganate, lithium manganate, lithium phosphateiron and lithium, etc.) and aluminum foil. The negative electrode consists of a current collector made of graphitized carbon material and copper foil. The battery is filled with an organic electrolyte solution.

In addition, a safety valve and PTC element (used in some cylindrical types) are installed to protect the battery from damage under abnormal conditions and output short circuits.

Detailed information

Original lithiumThe battery has a very low self-discharge and can be stored for 3 years. The effect will be better if stored in the refrigerator. It is a good idea to store primary lithium batteries in a low temperature location.

Lithium-ion batteries can be stored for more than six months at 20°C, because their self-discharge rate is very low and most of their capacity can berestored.

Lithium batteries have a self-discharge phenomenon. If the battery voltage is stored below 3.6V for a long time, the battery will overdischarge and damage the internal structure of the battery, thereby reducing the battery capacity. life. Therefore, lithium batteries stored for a long time need to be recharged every 3 to 6 months, that is, they should be charged at a voltage of 3.8 to 3.9 V (the Optimal storage voltage of lithium batteries is approximately 3.85 V) and do not recharge them. be fully charged.

Lithium batteries have a wide application temperature range. They can still be used outdoors during the northern winter, but their capacity will be significantly reduced if returned to room temperature, the capacity can be restored. Lithium-ion batteries cannot be recharged and recharging is veryvery dangerous. Other considerations, equivalent to lithium-ion batteries.
