Recently, Daikin Industries of Japan and Japan's high paper industry jointly developed a high heat resistance technology for lithium batteries for electric vehicles. The new technology does not require a battery cooling system, which reduces the weight of the car while reducing its own power consumption. The distance traveled by one charge can be increased by 30%-40%. It can also prevent battery self-ignition accidents and improve driving safety.

The existing lithium battery for a vehicle generates heat due to a chemical reaction, and when the temperature rises to 45 degrees or more, the power generation performance is lowered, and a cooling system needs to be assembled. During the high temperature season in summer, the whole operation of the cooling system can reduce the efficiency and shorten the driving distance by about 30%.
The new technology uses fluorine compounds instead of flammable electrolyte components, and the new electrolyte can work normally even if the temperature rises to 60 degrees. The insulating materials made from finely processed plant fibers are more resistant to high temperatures than the resin film products currently in common use. The reduction in the expansion ratio allows the heat resistance of the insulating member to be greatly improved; the adhesive used for the electrode is replaced with a highly heat-resistant material, and even if it is heated at a high temperature, it does not appear to be dissolved.
Headband Headphones have good sound field and are comfortable to wear, Bluetooth Headband Headphones can avoid scratching the ear canal; the sound quality of high, medium,and bass are very good, have a good sense of hearing even when playing symphony; The midrange effect of the headphones is thick, pop songs' hearing effect is very contagious, music effect is great.
Advantages:
1: Sound field is good, comfortable to wear.
2: No in-ear, avoid scratching the ear canal.
3: longer time to use, compare to in-ear earphone.
