Is the higher the battery capacity the better?

But for the same battery model, the nominal capacity (such as 600mAh) is the same, and the actual measured initial capacity is different: for example, one is 660mAh and the other is 605mAh, then is the 660mAh better than the 605mAh? The actual situation may be higher capacity The reason is that there are more things that add initial capacity in the electrode material, and the things used for electrode stabilization are reduced.As a result, after dozens of cycles of use, batteries with high capacity quickly fail in capacity, while batteries with low capacity are still strong. Many domestic battery cell manufacturers often use this method to obtain high-capacity batteries. However, after half a year of use, the standby time is a mess. Those AA nickel-metal hydride batteries for civilian use (that is, AA batteries) are generally 1400mAh, but they also have The standard ultra-high capacity (1600mAh) is the same. The price of increasing the capacity is sacrificing the cycle life. The manufacturer is not in the context of the modification of battery materials, and it is impossible to truly increase the battery capacity. The same The model of large-capacity spare lithium-ion battery has the same nominal capacity (for example, 600mAh), but the actual measured initial capacity is different. For example, one is 660mAh and the other is 605mAh, so will the 660mAh battery be better than the 605mAh battery? The actual situation is likely to be a battery with a higher capacity, because there are some additional initial capacity in the electrode material, which reduces the stability of the electrode. As a result, the capacity is higher after being used for dozens of times. The battery quickly becomes capacity exhausted, while the lower capacity battery is still strong. Many domestic cell processing manufacturers often use this method to obtain higher-capacity batteries, but the standby time for users after half a year of use is a mess. The AA Ni-MH batteries used (that is, AA batteries) are generally 1400mAh, but they still have standard ultra-high capacity (1600mAh). Many domestic cell processing manufacturers often use this method to obtain higher-capacity batteries, but the standby time for users after half a year of use is a mess. The AA Ni-MH batteries used (that is, AA batteries) are generally 1400mAh, but they still have standard ultra-high capacity (1600mAh). In fact, the principle is the same. The price of increasing capacity is sacrificing cycle life. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
