Lithium battery specification

The lithium battery specification is a method for explaining a lithium battery. The lithium battery terminal consumer understands the lithium battery specification and the lithium battery manufacturer understands the lithium battery specification has a thickness, inside and outside. Based on the customer experience and the focus of the manufacturer's technology, the lithium battery specifications can be divided into two parts: product type and nominal technical parameters. The following is a description of the 18650 lithium battery configured by Dongguan LARGE Electronics Co., Ltd. for the light curing machine.

First, the product type:

1. Product Name: The common name is “Rechargeable lithium ion battery”. If a certain type of battery has a special purpose, it can be named from the application point of view, such as a photocuring machine lithium battery.

2, model specifications: 18650/2200mAh / 3.7V, of which 2200mAh indicates lithium battery capacity, 3.7V indicates lithium battery voltage, 18650 indicates that the battery appearance is cylindrical, diameter 18mm, height 65mm. Manufacturers sometimes have internal numbers based on their own product series. For example, the internal number of the lithium battery of the curing machine in Dongguan LARGE is 16AQ1159-01.

Second, the product parameters:

The contents and setting sequence of the lithium battery parameters of various manufacturers are not exactly the same, but the basic parameters are all required. The parameters marked by the lithium battery of Dongguan LARGE curing machine have the following contents:

Item Number: 16AQ1159-01

Combination method: ICR18650-1S1P

Nominal voltage: 3.7V

Nominal capacity: 2200mAh

Nominal weight: 4.5g

Standard discharge continuous current: 0.2C

Maximum discharge continuous current: 1C

Working temperature: Charging: 0~45°C

Discharge: -20~60°C

Product size: MAX18.8*18.8*69.5mm

Finished product internal resistance: ≤180mΩ

Protection board: IC-S8261G3J+MOS-AO8810

Protection parameters: overcharge protection voltage / 4.28 ± 0.025V per string

Over-discharge protection voltage 3.0±0.05V

Over-current value: 1.5~2.5A

The above parameters are for reference only, but these parameter items are generally referred to in the lithium battery specification.

From the perspective of the lithium battery specification generation system, the product type is focused on the description of the use angle, emphasizing the needs of consumers, while the product parameters are based on a technical description, emphasizing the pursuit of producers. Lithium battery specifications are actually the same thing. The producer's product parameters are reasonable and true will be transformed into consumers' recognition of this type of product, which is the standard of the consumer's mind. In fact, both types of logos are reflected in the lithium battery specification.
