Why mobile phone performance is getting stronger and better but battery performance has not improved much

In fact, battery technology has advanced, but it is very small. It is currently impossible to make revolutionary changes and popularize. At present, mobile phone batteries on the market are basically lithium batteries, because lithium is a metal with very low potential among all metals. The use of lithium as a negative electrode has a higher rated voltage. Lithium batteries can have a higher energy density and per unit weight. The energy of lithium batteries is more than 5 times that of batteries, and lithium is not a heavy metal, which causes very little pollution to the environment. Its own low power escape rate, light weight and long service life are unmatched by other batteries, and have not been found yet. Batteries that are more suitable for large-area use than lithium batteries. If you want to increase the battery life of your mobile phone, you have to find a way to increase the energy density of the lithium battery, but the energy density has a great relationship with the lithium element itself. On the basis of the unchanged lithium element, the researchers have to constantly replace the electrolysis Liquid and cathode materials can barely increase the battery's endurance a little bit, and the annual improvement is only about 3%. Theoretically speaking, it’s improved by 3% every year. It should have made great progress in the past ten years. But in fact, electronic products have been updated faster. The transistors in the chip are all nanometers. The transistors become smaller and smaller. The ability to solve the problem has been improving, and the computing power of the chip has been getting stronger, so the power consumption is even greater. So it looks like there is no progress in battery technology, but in fact, there has been a lot of progress, but the chip has improved faster, smoothing the progress of battery technology. At the same time, it has been previously reported that graphene batteries are very promising batteries in the future. They can withstand temperatures up to 100 degrees Celsius and down to minus 50 degrees Celsius, and have more stable charge and discharge times than lithium batteries. They can also be placed in a fire. It will not explode, the battery life is stronger than lithium batteries, and it only takes a few minutes to charge, which is perfect.
