Charging for a few hours, can only play for a long time, the battery of the smart phone allows the little friends to vomit countless; charging one night, can only run about 100 kilometers, which makes many people who want to buy electric cars stop and stop... If a battery is charged The time is short, the cruising range is beyond your imagination, are you looking forward to it?
Supercapacitor batteries have entered people's field of vision. Supercapacitor battery is a new energy storage device that stores energy through polarized electrolyte. It generally uses activated carbon electrode material, which has high energy density and fast charging speed. A few days ago, some media reported that a foreign university developed a super-capacitor battery. This battery can be charged for a few seconds and the battery life can reach one week.
In addition to short charging time and long battery life, there are many advantages of super capacitor batteries. The lead-acid batteries and lithium batteries that we use now are lossy when used. When used for a period of time, the battery life will be greatly shortened, and the super-capacitor battery will not react chemically during charging and discharging, and there is almost no loss. Therefore, the cycle life is very long and can be recycled hundreds of thousands of times. Because it does not chemically react, supercapacitor batteries produce almost no pollution during production, use, and disassembly, and are more environmentally friendly than conventional batteries. In addition, the super capacitor battery also has the advantages of high energy conversion rate, strong discharge capacity, good ultra-low temperature characteristics, and convenient detection. Some insiders believe that super capacitor batteries will replace traditional batteries such as lithium batteries, becoming the first choice for electric vehicles and smart phone batteries .
However, supercapacitor batteries are not perfect, and it is still difficult to shake the market position of traditional batteries. Because the supercapacitor battery has a strong discharge capacity, it hides the risk of "energy burst". It is not only difficult to store electricity, but also may leak current, which has potential safety hazards. Supercapacitor batteries are not resistant to high temperatures, and excessive temperatures can affect normal use. In addition, the high cost has become a "blocker" for the large-scale commercial use of super capacitor batteries.
Both enterprises and consumers are turning their attention to batteries with short charging time and long battery life. There is no doubt that super capacitor batteries have the potential in this respect. As technology matures, the large-scale commercial use of supercapacitor batteries will not be too far away.
