The life of batteries has always been the focus of people’s attention. People often judge the performance of batteries by comparing the life of batteries. But in fact, the life of batteries is affected by many factors. We need to set some conditions in advance to compare the life of different batteries, such as the life of alkaline batteries of different sizes, the life of alkaline batteries of the same size produced by different manufacturers, ETC。, so that the comparison is more fair.
At present, lithium batteries and alkaline batteries are very common and popular batteries on the market. Many people are curious about which battery has a higher life. In fact, these two batteries are completely different types. If we only look at the data, there is no doubt that the life of lithium batteries is much higher than that of alkaline batteries. The service life of lithium batteries is usually 8-15 年, or even up to 20 年, while the service life of alkaline batteries is generally about 4 年. Secondly, lithium batteries can be reused, and their number of cycles can reach 3000-6000 times, or even higher. Alkaline batteries are disposable batteries, and they will fail when the power is used up.
But it cannot be said that lithium batteries are definitely better than alkaline batteries. We must admit that different devices and usage scenarios require different batteries. 例如, in electric cars, people use lithium batteries, while for small electronic devices such as alarm clocks, alkaline batteries are sufficient.
So, what factors affect the life of the battery?
In fact, there are many factors that affect the life of the battery, such as the internal materials of the battery, the capacity of the battery, the way the battery is used, the external environment, the manufacturer of the battery, ETC.
Like lithium batteries, or lithium-ion batteries, the internal materials use substances containing lithium elements, and the battery is charged and discharged by the movement of lithium ions between the positive and negative electrodes, so that the battery can be used many times. Alkaline batteries can only be disposable and have to be thrown away after use.
Moreover, the capacity of the battery has a great impact on the life. Generally speaking, of course, the larger the capacity of the battery, the longer the service life.
此外, the life of the battery is also greatly affected by temperature. In low temperature environments, the life of the battery will be reduced. If you have used an electric car, you will definitely feel that the endurance of electric vehicles in winter is significantly less than in summer.
All of the above factors are determined by the characteristics of the battery itself. In fact, external factors cannot be ignored. 例如, if consumers use the battery improperly, it will also damage the service life of the battery. Frequently completely exhausting the battery before charging, or leaving the battery in the device for a long time without using it, or mixing new and old batteries, ETC。, may reduce the life of the battery.
