Use carbon-containing nanotube materials to obtain excellent charging efficiency and power storage capacity

Researchers at the Massachusetts Institute of Technology found that the use of carbon-containing nanotube materials in the positive electrode of lithium batteries can achieve far better charging efficiency and storage capacity than the highest-end lithium batteries. The battery electrode assembly uses a stacking technology. The positive electrode is composed of no additives, high density and functionalized multi-walled carbon nanotubes. The negative electrode is lithium titanium oxide. The thickness of the battery electrode is only a few microns.

The energy output per unit weight of the lithium battery is 5 times higher than that of the traditional electrochemical capacitor, the power output is 10 times higher than that of the traditional lithium ion battery, and the cycle life is more than thousands of times, indicating that the carbon nanotube battery has a higher capacity than lithium. Longer battery life.

The new lithium battery is undoubtedly good news for users who use portable electronic products such as smart phones, but this carbon-containing nanotube battery is still in the laboratory research and development stage. The main reason for restricting the popularity of this new type of battery is that the carbon-containing nanotube substrate needs to be soaked in two different battery solutions before making the battery electrode, and this process is extremely time-consuming. The most feasible solution currently proposed is to replace the time-consuming process of immersing in the battery dissolving solution by spraying the carbon nanotube substrate with an alternative substance.

Although this electrode can be used initially for small portable devices, further research will also be used for larger devices such as automobiles. It is believed that this carbon nanotube battery will be available soon, and users of smart phones will no longer worry about the lack of power in the mobile phone.
