Queensland University of Science and Technology (QUT) in Australia is developing a new generation of super capacitors. In the future, you may not find huge batteries in electric cars, because the batteries will be placed on the walls, roof, doors, covers, floor and other places.

At that time, super capacitors were used in cars lithium battery The super capacitor has the advantages of ultra fast charging speed, ultra long service life, lighter weight, safety, etc. The killer is that it can instantly absorb or release extremely high energy, and the charging time is only a few minutes, while the lithium battery electric car at that time takes a few hours.

However, its fatal disadvantage at that time was that its energy density was very low, so how could the university make a breakthrough in the research and development of the new generation of super capacitors by improving the energy density. They said that the new generation of farad capacitor can store more energy than lithium battery. In the future, one vehicle will choose this type Farad capacitor A fully charged car can run 500 kilometers.

The team expects to apply it to cars within 5 years. It is worth mentioning that this battery is expected to be applied to smart phones.

whatever Super capacitor manufacturer The discharge current is called leakage current, which affects the self discharge of supercapacitor unit. Super capacitor module Similar to some secondary battery skills, the voltage of the supercapacitor also needs to be balanced when it is used in series. Because the supercapacitor has leakage current, the size of the internal parallel resistance determines the voltage distribution on the supercapacitor units in series. When the voltage of the supercapacitor is stable, the voltage of each unit will change with the leakage current, not with the capacitance. The larger the leakage current, the smaller the additional voltage. On the contrary, the smaller the leakage current, the higher the additional voltage.

Super capacitors are mainly discussed in China, Japan, South Korea, France, Germany, Canada and the United States. From the perspective of production planning and technical level, Asia is temporarily ahead.
