With the progress of technology and the expansion of demand, the electronic tag is also getting more and more well known. The volume is getting smaller based on a range of different applications, so the battery will become smaller and smaller.
So the electronic tag is now increasingly use button batteries, often selecting button batteries 3V lithium manganese button battery. Currently, produce this button battery manufacturers are beyond count in China. Button battery divided by chemical composition have: carbon, alkaline, zinc silver oxide, zinc - air, lithium manganese, nickel-cadmium rechargeable button cell batteries, nickel-metal hydride rechargeable button batteries etc. If the shape is single and laminated distinguish. Detailed speaking carbon button battery is the cheapest, basic is a little expensive, but have good discharge effect. The following will share with everyone lithium manganese button battery knowledge.
Lithium manganese disposable button battery rated voltage is 3V, termination voltage is 2V, typical working current is in 0.1-0.2mA. It uses the chemical properties are very stable manganese dioxide as the cathode material, with very high energy lithium metal as cathode material, with the electrolyte, so as to achieve discharge effect. The average annual reduction in capacity is not more than 2%, long storage life. The battery adopts a sealing structure, safe use. At present the various manufacturers, because the production process differences, and the battery raw material is different, so the price is different, generally speaking, Chinese production battery is worse than Japanese battery, but now the gap is more and more small, the Chinese battery and battery performance is very close to Japan. Why Chinese and Japanese battery, Chinese battery and battery performance will have very big difference? First, production process, quality control is the key reason, second, the different of battery raw material is quite large.
Technology question is the core secret for every manufacturer, also be each manufacturer's foothold, in this point, we can not known, but the problem of raw materials can be analysed, can be judged. Button battery core material also will affect the battery properties (that is, to exclude negative material is not sufficient condition, at present a lot of manufacturers from a profit point of view, reduce the poles of a battery raw materials, resulting in lack of battery power, is really hateful, it is not within our description) mainly have sealing rubber ring, manganese powder, separator and battery shell.
Sealing rubber ring, directly influence whether the battery leakage, and a battery storage performance, a sealing rubber ring is easy to aging, once aging, the leakage problems will emerge, in China, the sealing rubber ring is still a big gap with other countries. Manganese powder purity on the battery performance is great, impure manganese powder is able to lead to discharge not balance, inadequate capacity of such a phenomenon, it needs to look at the powder purity provided by metal powder suppliers. The diaphragm is an important raw material for placed level stability, diaphragm density is too thin, can fast discharge. Too much, may not put out of power. The battery shell is a good guarantee of battery electric conductivity. Currently the common battery shell has stainless steel and stainless iron on the market, wherein different materials on the battery also have very big difference.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
The Evolution and Impact of Abamectin and Emamectin Benzoate in Pest Control
Abamectin and its derivative, emamectin benzoate, have emerged as pivotal substances in the realm of pest control, offering a broad-spectrum efficacy against various pests while maintaining a favorable environmental profile. As the agricultural industry continues to evolve, these compounds have adapted to meet the growing challenges of pest resistance, expanding their market applications and maintaining cost-effectiveness despite rising production costs.
