The first part of electronic products, especially laptops and mobile phones, that fail is often the battery. This is no coincidence, but is determined by the characteristics of the battery itself and the environment in which it is used.
The life of batteries is limited, which is closely related to the chemical properties and physical structure of batteries. Lithium-ion batteries, as the most common batteries for electronic products, work on the principle that lithium ions move back and forth between the positive and negative electrodes to generate current. As the number of charge and discharge times increases, lithium ions gradually cannot completely return to the positive electrode, causing the battery capacity to decrease and eventually fail to work properly.
In addition to the characteristics of the battery itself, the usage environment will also accelerate battery aging. Environmental factors such as high temperature, humidity, and vibration will damage the battery and accelerate its aging. Laptops and mobile phones are often placed in high temperature environments, such as in a car under direct sunlight, or placed in pockets, where they come into contact with human body heat, causing the battery temperature to rise and accelerating aging.
In addition, frequent charging and discharging will also accelerate battery aging. Modern people are increasingly dependent on electronic products, and their mobile phones and laptops are used almost non-stop. Frequent charging and discharging will intensify the chemical reaction inside the battery and accelerate the decline of battery capacity.
Finally, the production process and quality of the battery are also important factors affecting the battery life. Some low-quality batteries have defects in internal materials and production processes, which are more likely to have problems, resulting in a shorter battery life.
In short, the damage of electronic product batteries is the result of the combined effect of multiple factors, including the characteristics of the battery itself, as well as the influence of the usage environment and usage habits.
In order to extend the life of electronic product batteries, we should try to avoid placing electronic products in high temperature environments, avoid frequent charging and discharging, choose high-quality batteries, and perform battery maintenance regularly.
