What are the reasons why lithium battery life is not long

Lithium battery life is not long, although memory and life are much better than traditional nickel-hydrogen batteries, about 500 charge and discharge will lose about 20%, and activation has not changed significantly. Recently, scientists from the Western Pacific National Laboratory in the United States used a powerful microscope to successfully observe the real-time state of lithium battery charging and discharging, and found the reason for this phenomenon. When the battery is in use, physical pressure will appear, causing the electrode to break. Each charge-discharge cycle will leave traces of lithium outside the electrode. These dead lithium can no longer be used in future charging and will cause a decrease in battery capacity. So the question is, how to deal with this phenomenon? The solution given by the scientists is to look for more stable metals such as magnesium, aluminum or copper to replace, but the performance is not as good as lithium batteries, so they must continue to find answers. In fact, people have never stopped about battery technology. On the one hand, they must find ways to increase battery capacity and charging speed. On the other hand, scientists have been looking for low-power electronic materials. I believe that in the near future, the power consumption problem of mobile phones and other electronic devices will be solved.
