Why the innovative technology to improve the battery of smartphones has not appeared

　　Imagine that if the mobile phone is not limited by power, then the CPU will no longer be limited due to power consumption. Mobile phones will be made thinner and thinner, and mobile phone manufacturers will have more bold innovation attempts. But why hasn't cell phone batteries made substantial progress over the years?

　　Batteries have become the most important bottleneck restricting the development of mobile phones. Modern smartphone batteries account for 40% of the volume of mobile phones, and the lack of power still bothers us, and mobile phones are still charged every day.

　　Imagine that if the mobile phone is not limited by power, then the CPU will no longer be limited due to power consumption. Mobile phones will be made thinner and thinner, and mobile phone manufacturers will have more bold innovation attempts.

　　But why hasn't cell phone batteries made substantial progress over the years?

　　After the capacity of mobile phone batteries is increased to 3000mAh, it is difficult to improve. Prior to this, the main battery development originated from the use of new materials. When the material is converted from nickel to metal lithium, the battery life of consumer electronics products is extremely large. Extended. Professor John Goodey, the father of lithium iron phosphate and an important scientist in the development of modern batteries, said that current research is mainly focused on improving the life of lithium batteries. "The periodic table of the elements is very limited," Goodyef said, so progress and promotion have become increasingly difficult.

　　At present, lithium batteries are still the most suitable choice for mobile phones. They are safe, light in weight, and strong in memory. The current methods to increase the battery capacity of mobile phones are mainly to increase the density of lithium batteries and increase the volume of the battery, but this is not a long-term solution. The density of lithium batteries is close to its theoretical maximum density.

　　In short, the periodic table of the elements has become a bottleneck in the improvement of mobile phone batteries. People have not been able to find a more suitable element than lithium to replace it.

　　However, in order to solve the pain points of power, mobile phone manufacturers have used all the tricks that can be used, such as dynamically adjusting the core operating frequency of the SoC, PSR self-refresh, Nega negative liquid crystal, co-processor, fast charging technology, 10nm or higher process Cpu and so on.
