What is the difference between 18650 and 18500 18350 lithium battery?

Introduction What is the difference between 18650 and 18500 lithium batteries and 18350 lithium batteries? 18650, 18500 and 18350 lithium batteries are simply different in terms of battery length, they represent respectively

What is the difference between 18650 and 18500 18350 lithium battery?

Lithium batteries 18650, 18500 and 18350 differ only in battery length. They represent 65 mm, 50 mm and 35 mm respectively. These are all cylindrical batteries with a diameter of 18mm.

The 18650 lithium battery is a lithium battery commonly used in electronic products and is often used as the battery core in laptop batteries. The rules for defining its model are: For example, the 18650 type refers to a cylindrical battery with a diameter of 18mm and a length of 65mm.

The diameter of the 18500 lithium battery is 18mm, the length is 50mm, and it is a cylindrical battery.

The diameter of the 18500 lithium battery is 18mm, the length is 35mm, and it is a cylindrical battery.

These batteries with different lengths and the same diameter are suitable for different occasions.

What does 4680 battery mean?

Oxideof lithium-cobalt

Name and identification of the second model of lithium battery

1. The battery logo consists of 3 letters followed by 5 cylindrical numbers or 6 square numbers

2. The first letter indicates the material of the negative electrode of the battery, I indicates lithium-ion with built-in battery, and L indicates lithium. metal electrode or lithium alloy electrode

3. The second letter indicates the battery cathode material, C is a cobalt-based electrode, N is a nickel-based electrode, M is a manganese-based electrode, and V is a vanadium-based electrode< /p>

4. The third letter represents the shape of the battery, R represents the cylindrical battery, L represents the square battery

5. of the cylindrical battery represent respectively the unit of diameter and height of the battery. Height in millimeters

The unit of degree is the tenth of a millimeter when the diameter or height is greater than or equal to 100mm. , a slash must be added between the two dimensions.

Square The six digits of the battery represent the thickness, width and height of the battery respectively, in millimeters if one of the three dimensions is higher or higher. equal to 100 mm, an oblique bar must be added between the dimensions. If any of the three dimensions is less than 1 mm, a slash must be added before that dimension. Add the letter t, and the unit of this dimension is one tenth of a. millimeter.

For example:

ICP083448 indicates that the cathode material of a square secondary lithium-ion battery is cobalt, with a thickness of about 8mm, a width of 'approximately 34 mm and a height of approximately 48 mm.

The 4680 battery is the battery developed by Tesla.

4680 battery refers to the newly launched Panaso brand Tesla series batterynic, named 4680 battery. Ternary lithium polymer batteries are ternary lithium batteries that use lithium-nickel-cobalt-manganese or lithium-nickel-cobalt aluminate as the cathode material.

The volume of 4680 battery cell is 5 times that of 21700. According to the situation category from 18650 to 21700, it is normal for the capacity to increase by 5 times without considering other technical improvements . So Tesla said energy boostFive times (ENERGY5X), to be honest, it's probably about 5 times.

The performance role of ternary lithium batteries

A relatively balanced material in terms of capacity and safety, and which has better cycle performance than normal lithium-cobalt. At first, due to technical reasons, its rated voltage is only 3.5-3.6V, which limits its usage range. With the continuous improvement of the formula and the improvement structurelle, the rated voltage of the battery has reached 3.7V, and its capacity has reached or exceeded the level of the lithium cobalt oxide battery.

CameronSino has focused on battery manufacturing technology for twenty years. It is safe and stable, has no explosion hazard, has strong battery life, long-lasting power, high charge conversion rate, does not heat up, has long life, durable and has production qualifications. The products have passed several certifications domestically and globally. This is a battery brand worth choosing.
