원통형 리튬 배터리에는 어떤 유형이 있습니까? 일반적인 원통형 리튬 배터리 모델 소개. Posted by batterymanufactory.com
With the development of lithium battery technology, there are more and more types of cylindrical lithium batteries. Cylindrical lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, and ternary materials. The three material system batteries have different advantages. Let's take a look at the models and specifications of cylindrical lithium batteries.
Cylindrical lithium-ion batteries
are usually represented by five-digit numbers. Counting from the left,
the first and second digits refer to the diameter of the battery, the
third and fourth digits refer to the height of the battery, and the
fifth digit represents a circle. There are many types of cylindrical
lithium batteries, the more common ones are 10400, 14500, 16340, 18650,
21700, 26650, 32650, etc.
1. 10440 battery
The 10440 battery is a lithium-ion battery
with a diameter of 10mm and a height of 44mm. It is the same size as
the AA battery we often call it. The capacity of this battery is
generally small, only a few hundred mAh. It is mainly used in mini
electronic products. Such as flashlights, mini stereos, amplifiers, etc.
2. 14500 battery
The
14500 battery is a lithium-ion battery with a diameter of 14mm and a
height of 50mm. This is also the size of the battery we have always
called the 5th battery. This battery is generally 3.7V or 3.2V, and its
nominal capacity is relatively small, which is smaller than that of the
10440 battery. Larger, generally 1600mAh, with superior discharge
performance, the most important application field is consumer
electronics, such as wireless audio, electric toys, digital cameras,
etc.
3. 16340 battery
The
16340 battery is a lithium-ion battery with a diameter of 16mm and a
height of 34mm. Because of the shorter height of the ruler and the
smaller capacity, it can be used in strong light flashlights, LED
flashlights, headlights, laser lights, lighting fixtures. etc. often
appear.
4. 18650 battery
The
18650 battery is a lithium-ion battery with a diameter of 18mm and a
height of 65mm. Its biggest feature is that it has a very high energy
density, almost reaching 170 Wh/kg, so this battery is a cost-effective
battery. We usually Most of the batteries that are often seen are this
kind of battery, because it is a relatively mature lithium-ion battery,
and the system quality is stable in all aspects. on the appliance.
5. 21700 battery
The
21700 battery is a lithium-ion battery with a diameter of 21mm and a
height of 70mm. Because of its increased volume and increased space
utilization, the energy density of the battery cell and the system can
be improved, and its volumetric energy density is much higher than 18650
type battery is widely used in digital, electric vehicles, balance
cars, solar energy lithium-ion battery street lights, LED lights, power
tools, etc. Manufacturers of this kind of battery mainly include Tesla,
Samsung, Panasonic, BAK, and Dynavolt.
6. 26650 battery
The
26650 battery is a lithium-ion battery with a diameter of 26mm and a
height of 65mm. The nominal voltage is 3.2V and the nominal capacity is
3200mAh. This battery has the characteristics of excellent capacity and
high consistency, and has gradually become a trend to replace the 18650
battery. , In terms of power lithium batteries, many products will
gradually favor this.
