I think many people want to know what type of impact battery we usually use some! If you do not know, you can come next, understand in detail, know some, more stockpile some common sense. The next is this article: "three major wireless audio battery types".
The first: wireless audio batteries using NiMH batteries
Introduction of NiMH battery: NiMH battery is a kind of battery with good performance. NiMH battery is divided into high voltage NiMH battery and low voltage NiMH battery. The positive active substance of NiMH battery is Ni(OH)2 (called NiO electrode), the negative active substance is metal hydride, also called hydrogen storage alloy (the electrode is called hydrogen storage electrode), and the electrolyte is 6 mol/L potassium hydroxide solution. NiMH batteries are increasingly noticed as an important direction for hydrogen energy applications.
NiMH batteries are divided into high-voltage NiMH batteries and low-voltage NiMH batteries. Low-voltage NiMH batteries have the following characteristics: (1) the battery voltage is 1.2 ~ 1.3V, comparable to cadmium nickel batteries; (2) high energy density, more than 1.5 times that of cadmium nickel batteries; (3) can be quickly charged and discharged, low temperature performance is good; (4) can be sealed, strong resistance to overcharge and discharge; (5) no dendritic crystal generation, can prevent short circuit within the battery; (6) safe and reliable no pollution to the environment, no memory effect, etc.
The second: wireless audio batteries using lithium polymer batteries
Lithium polymer batteries (Li-polymer, also known as polymer lithium ion batteries) have various advantages such as high specific energy, miniaturization, ultra-thinness, light weight and high safety. Based on such advantages, Li-polymer batteries can be made into any shape and capacity to meet the needs of various products; and it uses aluminum-plastic packaging, internal problems can be immediately manifested through the outer packaging, even if there are safety hazards, it will not explode, only bulge. In the polymer battery, the electrolyte plays the dual function of diaphragm and electrolyte: on the one hand, it separates the positive and negative materials like a diaphragm so that self-discharge and short circuit do not occur inside the battery, and on the other hand, it conducts lithium ions between the positive and negative electrodes like an electrolyte. Polymer electrolyte not only has good electrical conductivity, but also has the characteristics of light weight, good elasticity and easy film formation which are unique to polymer materials, and it also follows the development trend of light weight, safety, high efficiency and environmental protection of chemical power.
1、No battery leakage problem, its battery does not contain liquid electrolyte inside, using the solid in gel form.
2、It can be made into thin battery: with the capacity of 3.6V 400mAh, its thickness can be as thin as 0.5mm. 3、The battery can be designed into various shapes.
4、The battery can be bent and deformed: the maximum polymer battery can be bent about 90 degrees.
5、Can be made into a single high voltage: liquid electrolyte batteries can only be connected in series with several cells to get high voltage, polymer batteries can be made into multi-layer combination within a single one to achieve high voltage because there is no liquid in itself.
6、Capacity will be double than the same size of lithium-ion batteries.
The third type: wireless audio battery using 18650 lithium batteries
What is 18650 lithium battery ?
18650 means, 18mm in diameter and 65mm in length. And the model number of No.5 battery is 14500, 14mm in diameter and 50mm in length. General 18650 battery is used more in industry, civilian use is rare, common in the laptop battery and high-grade flashlight used more.
The role of 18650 lithium batteries and the use of uses
18650 battery life theory for cycle charging 1000 times. In addition, 18650 battery is widely used in electronic fields because of its good stability in work: commonly used in high-grade flashlight, portable power supply, wireless data transmitter, electric warm clothes and shoes, portable instruments, portable lighting equipment, portable printer, industrial instruments, medical instruments, wireless audio, etc.
