What are the outstanding advantages and problems of lead-acid batteries?

Lead-acid batteries have been one of the most commonly used batteries for humans in the past 100 years. This is important because of several outstanding advantages: 1) Low cost: only 0.6~0.7 rmb/Wh; 2) Simple preparation process: The investment in preparation equipment and workshops is small, much smaller than that of lithium batteries; 3) relatively safe: the possibility of explosive combustion is very low; 4) strong environmental adaptability: it has a wide working range, and the performance varies with temperature The change is not as drastic as the lithium battery, and the requirements for the temperature control system are lower; 5) Easy to recycle: It is easier to recycle the active materials from the used lead-acid battery; 6) The technology is mature, stable and reliable: technology with more than 100 years of history , The relevant experience is rich and it is worth relying on. However, traditional lead-acid batteries have always had their outstanding problems: 1) Life problems: Traditionally, only a few hundred times of life; 2) High-power working problems: Under the high-rate working conditions of 0.5C or more, 'sulfate' will occur. The phenomenon of “decay and acceleration” is also the root cause of the poor life of lead-acid batteries; 3) The energy density is not high: only 20~40Wh/kg, so most of the occasions with higher energy density choose lithium batteries This is also an important reason for the strong rise of lithium batteries in recent years; 4) Recycling: Although the recycling of lead-acid batteries is not difficult, the recycling mechanism is not sound and the people’s environmental awareness is not strong, leading to the recycling of lead-acid batteries. There are many irregular phenomena, which cause waste of resources and pollution of the environment. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
