Japan Develops Lithium-Ion Batteries That Increase Charging Speed ​​by Over 100 Times
According to media reports, the research team of Japan Bell Chemicals and Aichi University of Technology has developed a lithium-ion battery that has a charging rate that is more than 100 times faster. The use of organic materials independently developed by the battery research team allows the phone to charge only 10 minutes. Researchers are striving for the use of such batteries in portable terminals and electric cars for five years and are expected to dramatically change our lives in the near future.
It is reported that this lithium battery mixes carbon nanotubes into organic molecules known as TOT as a positive electrode material. As the number of electrons is increased and the conduction speed is increased, charging and discharging can be performed more efficiently. The lithium battery with a diameter of 1 cm in button size has been charged for 30 seconds and has been charged and discharged 5,000 times without any deterioration in performance. An electric car that requires a large capacity battery can significantly reduce the charging time if it is used.
Lithium batteries, which are now commonly used, use cobalt oxide in the positive electrode material, and charging of the same size button battery requires several hours. Because it is difficult to obtain a high current, the electric vehicle is equipped with a capacitor so as to instantaneously release a strong current under conditions such as acceleration. The newly developed lithium battery can also achieve high current flow, so no capacitors are required. If the battery is used in an electric vehicle, it can reduce costs and improve acceleration performance. In addition, lithium batteries use organic materials that will not be damaged if bent and stretched instantly. Therefore, it is expected to be applied to electronic paper and biosensors that can be rolled up.
Industry sources pointed out that at present, the development of China's new energy vehicles has entered a large-scale stage and has experienced a blowout. This leads to a period of rapid growth, but charging is still an important bottleneck restricting the development of new energy vehicles. Once lithium batteries are used in the field of electric vehicles, they will overturn the entire new energy automobile industry. Its commercial value should not be underestimated.
As the core element of this super lithium battery, the application prospects of carbon nanotubes have also proved to be very broad. Its super mechanical properties, excellent field emission performance, high hydrogen storage performance, potential chemical properties, etc. make carbon nanotubes Research and preparation has always been a research hotspot in the field of international nanotechnology and new materials. Carbon nanotubes are one of the most highly developed nanomaterials in nanomaterials. In addition to applications in the battery field, carbon nanotubes also have a high potential for applications such as wearable devices, smart homes, supercapacitors, information storage, and sensors.
