The reason why mobile phone battery life cannot change qualitatively is that it can only rely on the development of lithium-ion batteries, and the improvement rate of lithium batteries is far less than the growth rate of the demand for lithium batteries in smartphones.
I believe many people have this question: "Smartphones are better than previous feature phones, but lithium batteries are not durable. Why can't the battery life of mobile phones break through after so many years of development? We still need One or even two charges a day?
Indeed, after years of development of smartphones, insufficient battery life has become a chronic problem in the industry. Industry insiders pointed out that the key to breaking through the battery life bottleneck lies in the innovation of battery materials.
Smartphone performance improvements highlight battery shortcomings
In the era of feature phones, it was normal for the phone to be on standby for more than ten days, and users could even use it for a week without charging. At present, the lithium battery capacity of most smartphones is several times that of the feature phone era, but users need to charge it once or even twice a day.
The reason is that the development route of smartphones tends to have more and more functions, stronger and stronger performance, and larger and larger screens, resulting in a greatly increased energy consumption of mobile phones.
A survey on the shortcomings of the iPhone by FixYa, a Japanese smartphone user service company, showed that the number one problem was short battery life, with a proportion as high as 35%.
It can be seen that insufficient battery life of smartphones has become the biggest pain point in user experience.
The development of lithium batteries is approaching the zero point
The reason why mobile phone battery life cannot change qualitatively is that it can only rely on the development of lithium-ion batteries, and the improvement rate of lithium batteries is far less than the growth rate of the demand for lithium batteries in smartphones.
At present, the innovation rate of lithium battery materials is very slow, and most of them are improvements in manufacturing processes. As a result, the capacity of lithium batteries can only increase by about 10% every year.
Even Elon Musk and Tesla, who are known for their breakthrough innovations, have only made breakthroughs in battery management and have not made progress in the materials and technology of the battery itself. They still use traditional Panasonic lithium batteries.
In the field of mobile phones, it is even more special. The current trend is thin and light design, which is contradictory to the increase in battery capacity. The current weight-to-capacity ratio of lithium battery materials is about 150mA/g. Without good industrial design, simply increasing the battery capacity will make the appearance of the mobile phone terrible.
