Can supercapacitors replace lithium batteries in mobile phones?

In recent years, due to the strong promotion of renewable energy in various countries, supercapacitors have been a key focus of development in the field of new energy. With the popularization of electric cars, supercapacitors, which were born in the 1970s, have once again appeared in the public eye. It is known that supercapacitors have been used in various types of electric cars in the commercial field and have now been put into commercial use. The commercial field of supercapacitors is still being explored and developed.

In this field of exploration, whether aluminum batteries used in smartphones can be replaced with supercapacitors has attracted widespread attention, and many researchers are now conducting experiments. However, no supercapacitor that can be used on mobile phones has been launched yet. The main reason for this is that supercapacitors have low energy density and have the characteristics of fast charging and fast discharging, similar to pure supercapacitor electric buses, Traveling a certain distance ensures that you can arrive at your destination on time and complete a charging action. The entire charging process does not take a minute, and can be seamlessly connected. For example, in the car type, there is still a lithium battery that is used in conjunction with supercapacitors, which can maximize the guarantee that the car will not suddenly run out of power and stop during the journey, If supercapacitors are used on mobile phones, the same principle applies. Mobile phones cannot always be equipped with chargers or power banks. Therefore, phones that use supercapacitors will take ten minutes to charge for dozens of seconds, perhaps even shorter. If used together with lithium batteries, they may be able to greatly save battery life, but the meaning of their use is not significant.

Another thing is that mobile phones do not have enough space to install like sedan devices. What mobile phones are pursuing now is an ultra-thin body, and the shape of supercapacitors has not yet reached a square shape. It is also impossible for the design of mobile phones to accommodate a single component. Therefore, research and development are needed on the shape of supercapacitors, and the premise of research and development is to occupy how supercapacitors can effectively store electricity on mobile phones, Instead of leveraging the characteristics of fast charging and discharging, such an application environment is not practical at all.

Although supercapacitors have not yet been applied in the mobile phone industry, and there are currently no groundbreaking reports on technological research dominance, with the global promotion of the concept of renewable energy, the commercial field covered by supercapacitors is bound to expand significantly. The demand for lithium batteries in mobile phones is high in the global market, so with the combination of environmental protection and commerce, The use of supercapacitors on mobile phones is still foreseeable in the future.
