During this process, ions move between the cathode and the anode.

Higher-quality batteries can withstand a larger number of charging cycles before capacity degradation becomes noticeable. This is because they are designed with materials that have better structural stability and can better accommodate the repeated movement of ions. Additionally, advanced battery management systems in some power banks help optimize the charging process, reducing the wear on the battery and extending its lifespan.

It's important to note that factors such as temperature, charging speed, and usage patterns can also influence the longevity of a power bank. High temperatures can accelerate the aging process of the battery, while fast charging can generate more heat and put additional stress on the battery. Using the power bank within its recommended temperature range and avoiding extreme conditions can help prolong its lifespan.

Therefore, investing in power banks with superior battery technology can result in a longer lifespan.
